-The Solaris Porting Layer (SPL) is a Linux kernel module which provides
-many of the Solaris kernel APIs. This shim layer makes it possible to
-run Solaris kernel code in the Linux kernel with relatively minimal
-modification. This can be particularly useful when you want to track
-upstream Solaris development closely and do not want the overhead of
-maintaining a large patch which converts Solaris primitives to Linux
-primitives.
-
-To build packages for your distribution:
-
- $ ./configure
- $ make pkg
-
-If you are building directly from the git tree and not an officially
-released tarball you will need to generate the configure script.
-This can be done by executing the autogen.sh script after installing
-the GNU autotools for your distribution.
-
-To copy the kernel code inside your kernel source tree for builtin
-compilation:
-
- $ ./configure --enable-linux-builtin --with-linux=/usr/src/linux-...
- $ ./copy-builtin /usr/src/linux-...
-
-The SPL comes with an automated test suite called SPLAT. The test suite
-is implemented in two parts. There is a kernel module which contains
-the tests and a user space utility which controls which tests are run.
-To run the full test suite:
-
- $ sudo insmod ./module/splat/splat.ko
- $ sudo ./cmd/splat --all
-
-Full documentation for building, configuring, testing, and using the
-SPL can be found at: <http://zfsonlinux.org>

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

+## dummy dependencies for each header file. Too bad gcc doesn't do
+## this for us directly.

+
+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.
+
+Fine tuning of the installation directories:

+ --with-config=CONFIG Config file 'kernel|user|all|srpm'
+ --with-linux=PATH Path to kernel source
+ --with-linux-obj=PATH Path to kernel build objects
+
+Some influential environment variables:
+ CC C compiler command
+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

+# For projects using AC_CONFIG_AUX_DIR([foo]), Autoconf sets
+# $ac_aux_dir to '$srcdir/foo'. In other projects, it is set to
+# '$srcdir', '$srcdir/..', or '$srcdir/../..'.
+#
+# Of course, Automake must honor this variable whenever it calls a
+# tool from the auxiliary directory. The problem is that $srcdir (and
+# therefore $ac_aux_dir as well) can be either absolute or relative,
+# depending on how configure is run. This is pretty annoying, since
+# it makes $ac_aux_dir quite unusable in subdirectories: in the top
+# source directory, any form will work fine, but in subdirectories a
+# relative path needs to be adjusted first.
+#
+# $ac_aux_dir/missing
+# fails when called from a subdirectory if $ac_aux_dir is relative
+# $top_srcdir/$ac_aux_dir/missing
+# fails if $ac_aux_dir is absolute,
+# fails when called from a subdirectory in a VPATH build with
+# a relative $ac_aux_dir
+#
+# The reason of the latter failure is that $top_srcdir and $ac_aux_dir
+# are both prefixed by $srcdir. In an in-source build this is usually
+# harmless because $srcdir is '.', but things will broke when you
+# start a VPATH build or use an absolute $srcdir.
+#
+# So we could use something similar to $top_srcdir/$ac_aux_dir/missing,
+# iff we strip the leading $srcdir from $ac_aux_dir. That would be:
+# am_aux_dir='\$(top_srcdir)/'`expr "$ac_aux_dir" : "$srcdir//*\(.*\)"`
+# and then we would define $MISSING as
+# MISSING="\${SHELL} $am_aux_dir/missing"
+# This will work as long as MISSING is not called from configure, because
+# unfortunately $(top_srcdir) has no meaning in configure.
+# However there are other variables, like CC, which are often used in
+# configure, and could therefore not use this "fixed" $ac_aux_dir.
+#
+# Another solution, used here, is to always expand $ac_aux_dir to an
+# absolute PATH. The drawback is that using absolute paths prevent a
+# configured tree to be moved without reconfiguration.

-#
-# vdev_id: udev helper to generate user-friendly names for JBOD disks
-#
-# This script parses the file /etc/zfs/vdev_id.conf to map a
-# physical path in a storage topology to a channel name. The
-# channel name is combined with a disk enclosure slot number to
-# create an alias that reflects the physical location of the drive.
-# This is particularly helpful when it comes to tasks like replacing
-# failed drives. Slot numbers may also be re-mapped in case the
-# default numbering is unsatisfactory. The drive aliases will be
-# created as symbolic links in /dev/disk/by-vdev.
-#
-# The currently supported topologies are sas_direct and sas_switch.
-# A multipath mode is supported in which dm-mpath devices are
-# handled by examining the first-listed running component disk. In
-# multipath mode the configuration file should contain a channel
-# definition with the same name for each path to a given enclosure.
-#
-# The alias keyword provides a simple way to map already-existing
-# device symlinks to more convenient names. It is suitable for
-# small, static configurations or for sites that have some automated
-# way to generate the mapping file.
-#
-#
-# Some example configuration files are given below.

- * ZFS Fault Injector
- *
- * This userland component takes a set of options and uses libzpool to translate
- * from a user-visible object type and name to an internal representation.
- * There are two basic types of faults: device faults and data faults.
- *
- *
- * DEVICE FAULTS
- *
- * Errors can be injected into a particular vdev using the '-d' option. This
- * option takes a path or vdev GUID to uniquely identify the device within a
- * pool. There are two types of errors that can be injected, EIO and ENXIO,
- * that can be controlled through the '-e' option. The default is ENXIO. For
- * EIO failures, any attempt to read data from the device will return EIO, but
- * subsequent attempt to reopen the device will succeed. For ENXIO failures,
- * any attempt to read from the device will return EIO, but any attempt to
- * reopen the device will also return ENXIO.
- * For label faults, the -L option must be specified. This allows faults
- * to be injected into either the nvlist, uberblock, pad1, or pad2 region
- * of all the labels for the specified device.
- *
- * This form of the command looks like:
- *
- * zinject -d device [-e errno] [-L <uber | nvlist | pad1 | pad2>] pool
- *
- *
- * DATA FAULTS
- *
- * We begin with a tuple of the form:
- *
- * <type,level,range,object>
- *
- * type A string describing the type of data to target. Each type
- * implicitly describes how to interpret 'object'. Currently,
- * the following values are supported:
- *
- * data User data for a file
- * dnode Dnode for a file or directory
- *
- * The following MOS objects are special. Instead of injecting
- * errors on a particular object or blkid, we inject errors across
- * all objects of the given type.
- *
- * mos Any data in the MOS
- * mosdir object directory
- * config pool configuration
- * bpobj blkptr list
- * spacemap spacemap
- * metaslab metaslab
- * errlog persistent error log
- *
- * level Object level. Defaults to '0', not applicable to all types. If
- * a range is given, this corresponds to the indirect block
- * corresponding to the specific range.
- *
- * range A numerical range [start,end) within the object. Defaults to
- * the full size of the file.
- *
- * object A string describing the logical location of the object. For
- * files and directories (currently the only supported types),
- * this is the path of the object on disk.
- *
- * This is translated, via libzpool, into the following internal representation:
- *
- * <type,objset,object,level,range>
- *
- * These types should be self-explanatory. This tuple is then passed to the
- * kernel via a special ioctl() to initiate fault injection for the given
- * object. Note that 'type' is not strictly necessary for fault injection, but
- * is used when translating existing faults into a human-readable string.
- *
- *
- * The command itself takes one of the forms:
- *
- * zinject
- * zinject <-a | -u pool>
- * zinject -c <id|all>
- * zinject [-q] <-t type> [-f freq] [-u] [-a] [-m] [-e errno] [-l level]
- * [-r range] <object>
- * zinject [-f freq] [-a] [-m] [-u] -b objset:object:level:start:end pool
- *
- * With no arguments, the command prints all currently registered injection
- * handlers, with their numeric identifiers.
- *
- * The '-c' option will clear the given handler, or all handlers if 'all' is
- * specified.
- *
- * The '-e' option takes a string describing the errno to simulate. This must
- * be either 'io' or 'checksum'. In most cases this will result in the same
- * behavior, but RAID-Z will produce a different set of ereports for this
- * situation.
- *
- * The '-a', '-u', and '-m' flags toggle internal flush behavior. If '-a' is
- * specified, then the ARC cache is flushed appropriately. If '-u' is
- * specified, then the underlying SPA is unloaded. Either of these flags can be
- * specified independently of any other handlers. The '-m' flag automatically
- * does an unmount and remount of the underlying dataset to aid in flushing the
- * cache.
- *
- * The '-f' flag controls the frequency of errors injected, expressed as a
- * integer percentage between 1 and 100. The default is 100.
- *
- * The this form is responsible for actually injecting the handler into the
- * framework. It takes the arguments described above, translates them to the
- * internal tuple using libzpool, and then issues an ioctl() to register the
- * handler.
- *
- * The final form can target a specific bookmark, regardless of whether a
- * human-readable interface has been designed. It allows developers to specify
- * a particular block by number.

- * Functions to convert between a list of vdevs and an nvlist representing the
- * configuration. Each entry in the list can be one of:
- *
- * Device vdevs
- * disk=(path=..., devid=...)
- * file=(path=...)
- *
- * Group vdevs
- * raidz[1|2]=(...)
- * mirror=(...)
- *
- * Hot spares
- *
- * While the underlying implementation supports it, group vdevs cannot contain
- * other group vdevs. All userland verification of devices is contained within
- * this file. If successful, the nvlist returned can be passed directly to the
- * kernel; we've done as much verification as possible in userland.
- *
- * Hot spares are a special case, and passed down as an array of disk vdevs, at
- * the same level as the root of the vdev tree.
- *
- * The only function exported by this file is 'make_root_vdev'. The
- * function performs several passes:
- *
- * 1. Construct the vdev specification. Performs syntax validation and
- * makes sure each device is valid.
- * 2. Check for devices in use. Using libblkid to make sure that no
- * devices are also in use. Some can be overridden using the 'force'
- * flag, others cannot.
- * 3. Check for replication errors if the 'force' flag is not specified.
- * validates that the replication level is consistent across the
- * entire pool.
- * 4. Call libzfs to label any whole disks with an EFI label.

-/*
- * The objective of this program is to provide a DMU/ZAP/SPA stress test
- * that runs entirely in userland, is easy to use, and easy to extend.
- *
- * The overall design of the ztest program is as follows:
- *
- * (1) For each major functional area (e.g. adding vdevs to a pool,
- * creating and destroying datasets, reading and writing objects, etc)
- * we have a simple routine to test that functionality. These
- * individual routines do not have to do anything "stressful".
- *
- * (2) We turn these simple functionality tests into a stress test by
- * running them all in parallel, with as many threads as desired,
- * and spread across as many datasets, objects, and vdevs as desired.
- *
- * (3) While all this is happening, we inject faults into the pool to
- * verify that self-healing data really works.
- *
- * (4) Every time we open a dataset, we change its checksum and compression
- * functions. Thus even individual objects vary from block to block
- * in which checksum they use and whether they're compressed.
- *
- * (5) To verify that we never lose on-disk consistency after a crash,
- * we run the entire test in a child of the main process.
- * At random times, the child self-immolates with a SIGKILL.
- * This is the software equivalent of pulling the power cord.
- * The parent then runs the test again, using the existing
- * storage pool, as many times as desired. If backwards compatibility
- * testing is enabled ztest will sometimes run the "older" version
- * of ztest after a SIGKILL.
- *
- * (6) To verify that we don't have future leaks or temporal incursions,
- * many of the functional tests record the transaction group number
- * as part of their data. When reading old data, they verify that
- * the transaction group number is less than the current, open txg.
- * If you add a new test, please do this if applicable.
- *
- * (7) Threads are created with a reduced stack size, for sanity checking.
- * Therefore, it's important not to allocate huge buffers on the stack.
- *
- * When run with no arguments, ztest runs for about five minutes and
- * produces no output if successful. To get a little bit of information,
- * specify -V. To get more information, specify -VV, and so on.
- *
- * To turn this into an overnight stress test, use -T to specify run time.
- *
- * You can ask more more vdevs [-v], datasets [-d], or threads [-t]
- * to increase the pool capacity, fanout, and overall stress level.
- *
- * Use the -k option to set the desired frequency of kills.
- *
- * When ztest invokes itself it passes all relevant information through a
- * temporary file which is mmap-ed in the child process. This allows shared
- * memory to survive the exec syscall. The ztest_shared_hdr_t struct is always
- * stored at offset 0 of this file and contains information on the size and
- * number of shared structures in the file. The information stored in this file
- * must remain backwards compatible with older versions of ztest so that
- * ztest can invoke them during backwards compatibility testing (-B).

+Usage: $0 [OPTION]... [VAR=VALUE]...
+
+To assign environment variables (e.g., CC, CFLAGS...), specify them as
+VAR=VALUE. See below for descriptions of some of the useful variables.
+
+Defaults for the options are specified in brackets.
+
+Configuration:
+ -h, --help display this help and exit
+ --help=short display options specific to this package
+ --help=recursive display the short help of all the included packages
+ -V, --version display version information and exit
+ -q, --quiet, --silent do not print \`checking ...' messages
+ --cache-file=FILE cache test results in FILE [disabled]
+ -C, --config-cache alias for \`--cache-file=config.cache'
+ -n, --no-create do not create output files
+ --srcdir=DIR find the sources in DIR [configure dir or \`..']
+
+Installation directories:
+ --prefix=PREFIX install architecture-independent files in PREFIX
+ [$ac_default_prefix]
+ --exec-prefix=EPREFIX install architecture-dependent files in EPREFIX
+ [PREFIX]
+
+By default, \`make install' will install all the files in
+\`$ac_default_prefix/bin', \`$ac_default_prefix/lib' etc. You can specify
+an installation prefix other than \`$ac_default_prefix' using \`--prefix',
+for instance \`--prefix=\$HOME'.
+
+For better control, use the options below.

+ CFLAGS C compiler flags
+ LDFLAGS linker flags, e.g. -L<lib dir> if you have libraries in a
+ nonstandard directory <lib dir>
+ LIBS libraries to pass to the linker, e.g. -l<library>
+ CPPFLAGS (Objective) C/C++ preprocessor flags, e.g. -I<include dir> if
+ you have headers in a nonstandard directory <include dir>
+ CPP C preprocessor
+ CCAS assembler compiler command (defaults to CC)
+ CCASFLAGS assembler compiler flags (defaults to CFLAGS)
+
+Use these variables to override the choices made by `configure' or to help
+it to find libraries and programs with nonstandard names/locations.

-DESCRIPTION
- These script were written with the primary intention of being portable and
- usable on as many systems as possible.
-
- This is, in practice, usually not possible. But the intention is there.
- And it is a good one.
-
- They have been tested successfully on:
-
- * Debian GNU/Linux Wheezy
- * Debian GNU/Linux Jessie
- * Ubuntu Trusty
- * CentOS 6.0
- * CentOS 6.6
- * Gentoo
-
-SUPPORT
- If you find that they don't work for your platform, please report this
- at the ZFS On Linux issue tracker at https://github.com/zfsonlinux/zfs/issues.
-
- Please include:
-
- * Distribution name
- * Distribution version
- * Where to find an install CD image
- * Architecture
-
- If you have code to share that fixes the problem, that is much better.
- But please remember to try your best keep portability in mind. If you
- suspect that what you're writing/modifying won't work on anything else
- than your distribution, please make sure to put that code in appropriate
- if/else/fi code.
-
- It currently MUST be bash (or fully compatible) for this to work.
-
- If you're making your own distribution and you want the scripts to
- work on that, the biggest problem you'll (probably) have is the part
- at the beginning of the "zfs-functions.in" file which sets up the
- logging output.
-
-INSTALLING INIT SCRIPT LINKS
- To setup the init script links in /etc/rc?.d manually on a Debian GNU/Linux
- (or derived) system, run the following commands (the order is important!):
-
- update-rc.d zfs-import start 07 S . stop 07 0 1 6 .
- update-rc.d zfs-mount start 02 2 3 4 5 . stop 06 0 1 6 .
- update-rc.d zfs-zed start 07 2 3 4 5 . stop 08 0 1 6 .
- update-rc.d zfs-share start 27 2 3 4 5 . stop 05 0 1 6 .
-
- To do the same on RedHat, Fedora and/or CentOS:
-
- chkconfig zfs-import
- chkconfig zfs-mount
- chkconfig zfs-zed
- chkconfig zfs-share
-
- On Gentoo:
-
- rc-update add zfs-import boot
- rc-update add zfs-mount boot
- rc-update add zfs-zed default
- rc-update add zfs-share default
-
- The idea here is to make sure all of the ZFS filesystems, including possibly
- separate datasets like /var, are mounted before anything else is started.
-
- Then, ZED, which depends on /var, can be started. It will consume and act
- on events that occurred before it started. ZED may also play a role in
- sharing filesystems in the future, so it is important to start before the
- 'share' service.
-
- Finally, we share filesystems configured with the share\* property.
-# This is a script with common functions etc used by zfs-import, zfs-mount,
-# zfs-share and zfs-zed.
-#
-# It is _NOT_ to be called independently
-#
-# Released under the 2-clause BSD license.
-#
-# The original script that acted as a template for this script came from
-# the Debian GNU/Linux kFreeBSD ZFS packages (which did not include a
-# licensing stansa) in the commit dated Mar 24, 2011:
-# https://github.com/zfsonlinux/pkg-zfs/commit/80a3ae582b59c0250d7912ba794dca9e669e605a

- *
- * This is an addition to the zfs device driver to add, modify and remove SMB
- * shares using the 'net share' command that comes with Samba.
- *
- * TESTING
- * Make sure that samba listens to 'localhost' (127.0.0.1) and that the options
- * 'usershare max shares' and 'usershare owner only' have been rewied/set
- * accordingly (see zfs(8) for information).
- *
- * Once configuration in samba have been done, test that this
- * works with the following three commands (in this case, my ZFS
- * filesystem is called 'share/Test1'):
- *
- * (root)# net -U root -S 127.0.0.1 usershare add Test1 /share/Test1 \
- * "Comment: /share/Test1" "Everyone:F"
- * (root)# net usershare list | grep -i test
- * (root)# net -U root -S 127.0.0.1 usershare delete Test1
- *
- * The first command will create a user share that gives everyone full access.
- * To limit the access below that, use normal UNIX commands (chmod, chown etc).

- *
- * KSTAT_FLAG_VAR_SIZE:

- * The size of the kstat you are creating will vary over time.
- * For example, you may want to use the kstat mechanism to
- * export a linked list. NOTE: The kstat framework does not
- * manage the data section, so all variable-size kstats must be
- * virtual kstats. Moreover, variable-size kstats MUST employ
- * kstat data locking to prevent data-size races with kstat
- * clients. See the section on "kstat snapshot" for details.
- *
- * KSTAT_FLAG_WRITABLE:
- *
- * Makes the kstat's data section writable by root.
- * The ks_snapshot routine (see below) does not need to check for
- * this; permission checking is handled in the kstat driver.
- *
- * KSTAT_FLAG_PERSISTENT:
- *
- * Indicates that this kstat is to be persistent over time.
- * For persistent kstats, kstat_delete() simply marks the
- * kstat as dormant; a subsequent kstat_create() reactivates
- * the kstat. This feature is provided so that statistics
- * are not lost across driver close/open (e.g., raw disk I/O
- * on a disk with no mounted partitions.)
- * NOTE: Persistent kstats cannot be virtual, since ks_data
- * points to garbage as soon as the driver goes away.
- *
- * The following flags are maintained by the kstat framework:
- *
- * KSTAT_FLAG_DORMANT:
- *
- * For persistent kstats, indicates that the kstat is in the
- * dormant state (e.g., the corresponding device is closed).
- *
- * KSTAT_FLAG_INVALID:
- *
- * This flag is set when a kstat is in a transitional state,
- * e.g. between kstat_create() and kstat_install().
- * kstat clients must not attempt to access the kstat's data

- * Dynamic update support
- *
- * The kstat mechanism allows for an optional ks_update function to update
- * kstat data. This is useful for drivers where the underlying device
- * keeps cheap hardware stats, but extraction is expensive. Instead of
- * constantly keeping the kstat data section up to date, you can supply a
- * ks_update function which updates the kstat's data section on demand.
- * To take advantage of this feature, simply set the ks_update field before
- * calling kstat_install().
- *
- * The ks_update function, if supplied, must have the following structure:
- *
- * int
- * foo_kstat_update(kstat_t *ksp, int rw)
- * {
- * if (rw == KSTAT_WRITE) {
- * ... update the native stats from ksp->ks_data;
- * return EACCES if you don't support this
- * } else {
- * ... update ksp->ks_data from the native stats
- * }
- * }
- *
- * The ks_update return codes are: 0 for success, EACCES if you don't allow
- * KSTAT_WRITE, and EIO for any other type of error.
- *
- * In general, the ks_update function may need to refer to provider-private
- * data; for example, it may need a pointer to the provider's raw statistics.
- * The ks_private field is available for this purpose. Its use is entirely
- * at the provider's discretion.
- *
- * All variable-size kstats MUST supply a ks_update routine, which computes
- * and sets ks_data_size (and ks_ndata if that is meaningful), since these
- * are needed to perform kstat snapshots (see below).
- *
- * No kstat locking should be done inside the ks_update routine. The caller
- * will already be holding the kstat's ks_lock (to ensure consistent data).

-
-/*
- * Kstat snapshot
- *
- * In order to get a consistent view of a kstat's data, clients must obey
- * the kstat's locking strategy. However, these clients may need to perform
- * operations on the data which could cause a fault (e.g. copyout()), or
- * operations which are simply expensive. Doing so could cause deadlock
- * (e.g. if you're holding a disk's kstat lock which is ultimately required
- * to resolve a copyout() fault), performance degradation (since the providers'
- * activity is serialized at the kstat lock), device timing problems, etc.
- *
- * To avoid these problems, kstat data is provided via snapshots. Taking
- * a snapshot is a simple process: allocate a wired-down kernel buffer,
- * acquire the kstat's data lock, copy the data into the buffer ("take the
- * snapshot"), and release the lock. This ensures that the kstat's data lock
- * will be held as briefly as possible, and that no faults will occur while
- * the lock is held.
- *
- * Normally, the snapshot is taken by default_kstat_snapshot(), which
- * timestamps the data (sets ks_snaptime), copies it, and does a little
- * massaging to deal with incomplete transactions on i/o kstats. However,
- * this routine only works for kstats with contiguous data (the typical case).
- * If you create a kstat whose data is, say, a linked list, you must provide
- * your own ks_snapshot routine. The routine you supply must have the
- * following prototype (replace "foo" with something appropriate):
- *
- * int foo_kstat_snapshot(kstat_t *ksp, void *buf, int rw);
- *
- * The minimal snapshot routine -- one which copies contiguous data that
- * doesn't need any massaging -- would be this:
- *
- * ksp->ks_snaptime = gethrtime();
- * if (rw == KSTAT_WRITE)
- * bcopy(buf, ksp->ks_data, ksp->ks_data_size);
- * else
- * bcopy(ksp->ks_data, buf, ksp->ks_data_size);
- * return (0);
- *
- * A more illuminating example is taking a snapshot of a linked list:
- *
- * ksp->ks_snaptime = gethrtime();
- * if (rw == KSTAT_WRITE)
- * return (EACCES); ... See below ...
- * for (foo = first_foo; foo; foo = foo->next) {
- * bcopy((char *) foo, (char *) buf, sizeof (struct foo));
- * buf = ((struct foo *) buf) + 1;
- * }
- * return (0);
- *
- * In the example above, we have decided that we don't want to allow
- * KSTAT_WRITE access, so we return EACCES if this is attempted.
- *
- * The key points are:
- *
- * (1) ks_snaptime must be set (via gethrtime()) to timestamp the data.
- * (2) Data gets copied from the kstat to the buffer on KSTAT_READ,
- * and from the buffer to the kstat on KSTAT_WRITE.
- * (3) ks_snapshot return values are: 0 for success, EACCES if you
- * don't allow KSTAT_WRITE, and EIO for any other type of error.
- *
- * Named kstats (see section on "Named statistics" below) containing long
- * strings (KSTAT_DATA_STRING) need special handling. The kstat driver
- * assumes that all strings are copied into the buffer after the array of
- * named kstats, and the pointers (KSTAT_NAMED_STR_PTR()) are updated to point
- * into the copy within the buffer. The default snapshot routine does this,
- * but overriding routines should contain at least the following:
- *
- * if (rw == KSTAT_READ) {
- * kstat_named_t *knp = buf;
- * char *end = knp + ksp->ks_ndata;
- * uint_t i;
- *
- * ... Do the regular copy ...
- * bcopy(ksp->ks_data, buf, sizeof (kstat_named_t) * ksp->ks_ndata);
- *
- * for (i = 0; i < ksp->ks_ndata; i++, knp++) {
- * if (knp[i].data_type == KSTAT_DATA_STRING &&
- * KSTAT_NAMED_STR_PTR(knp) != NULL) {
- * bcopy(KSTAT_NAMED_STR_PTR(knp), end,
- * KSTAT_NAMED_STR_BUFLEN(knp));
- * KSTAT_NAMED_STR_PTR(knp) = end;
- * end += KSTAT_NAMED_STR_BUFLEN(knp);

- * of "active" time. Queue length statistics are kept as a
- * running sum of the product of queue length and elapsed time
- * at that length -- i.e., a Riemann sum for queue length

- *
- * At each change of state (entry or exit from the queue),
- * we add the elapsed time (since the previous state change)
- * to the active time if the queue length was non-zero during
- * that interval; and we add the product of the elapsed time
- * times the queue length to the running length*time sum.
- *
- * This method is generalizable to measuring residency
- * in any defined system: instead of queue lengths, think
- * of "outstanding RPC calls to server X".
- *
- * A large number of I/O subsystems have at least two basic
- * "lists" of transactions they manage: one for transactions
- * that have been accepted for processing but for which processing
- * has yet to begin, and one for transactions which are actively
- * being processed (but not done). For this reason, two cumulative
- * time statistics are defined here: wait (pre-service) time,
- * and run (service) time.
- *
- * All times are 64-bit nanoseconds (hrtime_t), as returned by
- * gethrtime().
- *
- * The units of cumulative busy time are accumulated nanoseconds.
- * The units of cumulative length*time products are elapsed time
- * times queue length.
- *
- * Updates to the fields below are performed implicitly by calls to
- * these five functions:
- *
- * kstat_waitq_enter()
- * kstat_waitq_exit()
- * kstat_runq_enter()
- * kstat_runq_exit()
- *
- * kstat_waitq_to_runq() (see below)
- * kstat_runq_back_to_waitq() (see below)
- *
- * Since kstat_waitq_exit() is typically followed immediately
- * by kstat_runq_enter(), there is a single kstat_waitq_to_runq()
- * function which performs both operations. This is a performance
- * win since only one timestamp is required.
- *
- * In some instances, it may be necessary to move a request from
- * the run queue back to the wait queue, e.g. for write throttling.
- * For these situations, call kstat_runq_back_to_waitq().
- *

- * Adding and deleting kstats.
- *
- * The typical sequence to add a kstat is:
- *
- * ksp = kstat_create(module, instance, name, class, type, ndata, flags);
- * if (ksp) {
- * ... provider initialization, if necessary
- * kstat_install(ksp);
- * }
- *
- * There are three logically distinct steps here:
- *
- * Step 1: System Initialization (kstat_create)
- *
- * kstat_create() performs system initialization. kstat_create()
- * allocates memory for the entire kstat (header plus data), initializes
- * all header fields, initializes the data section to all zeroes, assigns
- * a unique KID, and puts the kstat onto the system's kstat chain.
- * The returned kstat is marked invalid (KSTAT_FLAG_INVALID is set),
- * because the provider (caller) has not yet had a chance to initialize
- * the data section.
- *
- * By default, kstats are exported to all zones on the system. A kstat may be
- * created via kstat_create_zone() to specify a zone to which the statistics
- * should be exported. kstat_zone_add() may be used to specify additional
- * zones to which the statistics are to be exported.
- *
- * Step 2: Provider Initialization
- *
- * The provider performs any necessary initialization of the data section,
- * e.g. setting the name fields in a KSTAT_TYPE_NAMED. Virtual kstats set
- * the ks_data field at this time. The provider may also set the ks_update,
- * ks_snapshot, ks_private, and ks_lock fields if necessary.
- *
- * Step 3: Installation (kstat_install)
- *
- * Once the kstat is completely initialized, kstat_install() clears the
- * INVALID flag, thus making the kstat accessible to the outside world.
- * kstat_install() also clears the DORMANT flag for persistent kstats.
- *
- * Removing a kstat from the system
- *
- * kstat_delete(ksp) removes ksp from the kstat chain and frees all
- * associated system resources. NOTE: When you call kstat_delete(),
- * you must NOT be holding that kstat's ks_lock. Otherwise, you may
- * deadlock with a kstat reader.
- *
- * Persistent kstats
- *
- * From the provider's point of view, persistence is transparent. The only
- * difference between ephemeral (normal) kstats and persistent kstats
- * is that you pass KSTAT_FLAG_PERSISTENT to kstat_create(). Magically,
- * this has the effect of making your data visible even when you're
- * not home. Persistence is important to tools like iostat, which want
- * to get a meaningful picture of disk activity. Without persistence,
- * raw disk i/o statistics could never accumulate: they would come and
- * go with each open/close of the raw device.
- *
- * The magic of persistence works by slightly altering the behavior of
- * kstat_create() and kstat_delete(). The first call to kstat_create()
- * creates a new kstat, as usual. However, kstat_delete() does not
- * actually delete the kstat: it performs one final update of the data
- * (i.e., calls the ks_update routine), marks the kstat as dormant, and
- * sets the ks_lock, ks_update, ks_private, and ks_snapshot fields back
- * to their default values (since they might otherwise point to garbage,
- * e.g. if the provider is going away). kstat clients can still access
- * the dormant kstat just like a live kstat; they just continue to see
- * the final data values as long as the kstat remains dormant.
- * All subsequent kstat_create() calls simply find the already-existing,
- * dormant kstat and return a pointer to it, without altering any fields.
- * The provider then performs its usual initialization sequence, and
- * calls kstat_install(). kstat_install() uses the old data values to
- * initialize the native data (i.e., ks_update is called with KSTAT_WRITE),
- * thus making it seem like you were never gone.

- * The interface consists of the following sequence of functions:

- * changelist_gather()
- * changelist_prefix()
- * < change property >
- * changelist_postfix()
- * changelist_free()
- *
- * Other interfaces:
- *
- * changelist_remove() - remove a node from a gathered list
- * changelist_rename() - renames all datasets appropriately when doing a rename
- * changelist_unshare() - unshares all the nodes in a given changelist
- * changelist_haszonedchild() - check if there is any child exported to
- * a local zone

- * home
- * |
- * +----+----+
- * | |
- * v v ws
- * bar baz |
- * | |
- * v v
- * @yesterday ----> foo
- *
- * In order to construct this graph, we have to walk every dataset in the pool,

- * parent. The parent only keeps track of the number of clones.
- *
- * In the normal case (without clones) this would be rather expensive. To avoid
- * unnecessary computation, we first try a walk of the subtree hierarchy
- * starting from the initial node. At each dataset, we construct a node in the
- * graph and an edge leading from its parent. If we don't see any snapshots
- * with a non-zero clone count, then we are finished.
- *
- * If we do find a cloned snapshot, then we finish the walk of the current
- * subtree, but indicate that we need to do a complete walk. We then perform a
- * global walk of all datasets, avoiding the subtree we already processed.
- *
- * At the end of this, we'll end up with a directed graph of all relevant (and
- * possible some irrelevant) datasets in the system. We need to both find our
- * limiting subgraph and determine a safe ordering in which to destroy the
- * datasets. We do a topological ordering of our graph starting at our target
- * dataset, and then walk the results in reverse.
- *
- * It's possible for the graph to have cycles if, for example, the user renames
- * a clone to be the parent of its origin snapshot. The user can request to
- * generate an error in this case, or ignore the cycle and continue.
- *
- * When removing datasets, we want to destroy the snapshots in chronological
- * order (because this is the most efficient method). In order to accomplish
- * this, we store the creation transaction group with each vertex and keep each
- * vertex's edges sorted according to this value. The topological sort will
- * automatically walk the snapshots in the correct order.

- * LibZFS_Core (lzc) is intended to replace most functionality in libzfs.
- * It has the following characteristics:
- *
- * - Thread Safe. libzfs_core is accessible concurrently from multiple
- * threads. This is accomplished primarily by avoiding global data
- * (e.g. caching). Since it's thread-safe, there is no reason for a
- * process to have multiple libzfs "instances". Therefore, we store
- * our few pieces of data (e.g. the file descriptor) in global
- * variables. The fd is reference-counted so that the libzfs_core
- * library can be "initialized" multiple times (e.g. by different
- * consumers within the same process).
- *
- * - Committed Interface. The libzfs_core interface will be committed,
- * therefore consumers can compile against it and be confident that
- * their code will continue to work on future releases of this code.
- * Currently, the interface is Evolving (not Committed), but we intend
- * to commit to it once it is more complete and we determine that it
- * meets the needs of all consumers.
- *
- * - Programmatic Error Handling. libzfs_core communicates errors with
- * defined error numbers, and doesn't print anything to stdout/stderr.
- *
- * - Thin Layer. libzfs_core is a thin layer, marshaling arguments
- * to/from the kernel ioctls. There is generally a 1:1 correspondence
- * between libzfs_core functions and ioctls to /dev/zfs.
- *
- * - Clear Atomicity. Because libzfs_core functions are generally 1:1
- * with kernel ioctls, and kernel ioctls are general atomic, each
- * libzfs_core function is atomic. For example, creating multiple
- * snapshots with a single call to lzc_snapshot() is atomic -- it
- * can't fail with only some of the requested snapshots created, even
- * in the event of power loss or system crash.
- *
- * - Continued libzfs Support. Some higher-level operations (e.g.
- * support for "zfs send -R") are too complicated to fit the scope of
- * libzfs_core. This functionality will continue to live in libzfs.
- * Where appropriate, libzfs will use the underlying atomic operations
- * of libzfs_core. For example, libzfs may implement "zfs send -R |
- * zfs receive" by using individual "send one snapshot", rename,
- * destroy, and "receive one snapshot" operations in libzfs_core.
- * /sbin/zfs and /zbin/zpool will link with both libzfs and
- * libzfs_core. Other consumers should aim to use only libzfs_core,
- * since that will be the supported, stable interface going forwards.

-.TH cstyle 1 "28 March 2005"
-.SH NAME
-.I cstyle
-\- check for some common stylistic errors in C source files
-.SH SYNOPSIS
-\fBcstyle [-chpvCP] [-o constructs] [file...]\fP
-.LP
-.SH DESCRIPTION
-.IX "OS-Net build tools" "cstyle" "" "\fBcstyle\fP"
-.LP
-.I cstyle
-inspects C source files (*.c and *.h) for common sylistic errors. It
-attempts to check for the cstyle documented in
-\fIhttp://www.cis.upenn.edu/~lee/06cse480/data/cstyle.ms.pdf\fP.
-Note that there is much in that document that
-.I cannot
-be checked for; just because your code is \fBcstyle(1)\fP clean does not
-mean that you've followed Sun's C style. \fICaveat emptor\fP.
-.LP
-.SH OPTIONS
-.LP
-The following options are supported:
-.TP 4
-.B \-c
-Check continuation line indentation inside of functions. Sun's C style
-states that all statements must be indented to an appropriate tab stop,
-and any continuation lines after them must be indented \fIexactly\fP four
-spaces from the start line. This option enables a series of checks
-designed to find contination line problems within functions only. The
-checks have some limitations; see CONTINUATION CHECKING, below.
-.LP
-.TP 4
-.B \-h
-Performs heuristic checks that are sometimes wrong. Not generally used.
-.LP
-.TP 4
-.B \-p
-Performs some of the more picky checks. Includes ANSI #else and #endif
-rules, and tries to detect spaces after casts. Used as part of the
-putback checks.
-.LP
-.TP 4
-.B \-v
-Verbose output; includes the text of the line of error, and, for
-\fB-c\fP, the first statement in the current continuation block.
-.LP
-.TP 4
-.B \-C
-Ignore errors in header comments (i.e. block comments starting in the
-first column). Not generally used.
-.LP
-.TP 4
-.B \-P
-Check for use of non-POSIX types. Historically, types like "u_int" and
-"u_long" were used, but they are now deprecated in favor of the POSIX
-types uint_t, ulong_t, etc. This detects any use of the deprecated
-types. Used as part of the putback checks.
-.LP
-.TP 4
-.B \-o \fIconstructs\fP
-Allow a comma-seperated list of additional constructs. Available
-constructs include:
-.LP
-.TP 10
-.B doxygen
-Allow doxygen-style block comments (\fB/**\fP and \fB/*!\fP)
-.LP
-.TP 10
-.B splint
-Allow splint-style lint comments (\fB/*@...@*/\fP)
-.LP
-.SH NOTES
-.LP
-The cstyle rule for the OS/Net consolidation is that all new files must
-be \fB-pP\fP clean. For existing files, the following invocations are
-run against both the old and new files:
-.LP
-.TP 4
-\fBcstyle file\fB
-.LP
-.TP 4
-\fBcstyle -p file\fB
-.LP
-.TP 4
-\fBcstyle -pP file\fB
-.LP
-If the old file gave no errors for one of the invocations, the new file
-must also give no errors. This way, files can only become more clean.
-.LP
-.SH CONTINUATION CHECKING
-.LP
-The continuation checker is a resonably simple state machine that knows
-something about how C is layed out, and can match parenthesis, etc. over
-multiple lines. It does have some limitations:
-.LP
-.TP 4
-.B 1.
-Preprocessor macros which cause unmatched parenthesis will confuse the
-checker for that line. To fix this, you'll need to make sure that each
-branch of the #if statement has balanced parenthesis.
-.LP
-.TP 4
-.B 2.
-Some \fBcpp\fP macros do not require ;s after them. Any such macros
-*must* be ALL_CAPS; any lower case letters will cause bad output.
-.LP
-The bad output will generally be corrected after the next \fB;\fP,
-\fB{\fP, or \fB}\fP.
-.LP
-Some continuation error messages deserve some additional explanation
-.LP
-.TP 4
-.B
-multiple statements continued over multiple lines
-A multi-line statement which is not broken at statement
-boundries. For example:
-.RS 4
-.HP 4
-if (this_is_a_long_variable == another_variable) a =
-.br
-b + c;
-.LP
-Will trigger this error. Instead, do:
-.HP 8
-if (this_is_a_long_variable == another_variable)
-.br
-a = b + c;
-.RE
-.LP
-.TP 4
-.B
-empty if/for/while body not on its own line
-For visibility, empty bodies for if, for, and while statements should be
-on their own line. For example:
-.RS 4
-.HP 4
-while (do_something(&x) == 0);
-.LP
-Will trigger this error. Instead, do:
-.HP 8
-while (do_something(&x) == 0)
-.br
-;
-.RE

-.TH ztest 1 "2009 NOV 01" "ZFS on Linux" "User Commands"
-
-.SH NAME
-\fBztest\fR \- was written by the ZFS Developers as a ZFS unit test.
-.SH SYNOPSIS
-.LP
-.BI "ztest <options>"
-.SH DESCRIPTION
-.LP
-This manual page documents briefly the \fBztest\fR command.
-.LP
-\fBztest\fR was written by the ZFS Developers as a ZFS unit test. The
-tool was developed in tandem with the ZFS functionality and was
-executed nightly as one of the many regression test against the daily
-build. As features were added to ZFS, unit tests were also added to
-\fBztest\fR. In addition, a separate test development team wrote and
-executed more functional and stress tests.
-.LP
-By default \fBztest\fR runs for ten minutes and uses block files
-(stored in /tmp) to create pools rather than using physical disks.
-Block files afford \fBztest\fR its flexibility to play around with
-zpool components without requiring large hardware configurations.
-However, storing the block files in /tmp may not work for you if you
-have a small tmp directory.
-.LP
-By default is non-verbose. This is why entering the command above will
-result in \fBztest\fR quietly executing for 5 minutes. The -V option
-can be used to increase the verbosity of the tool. Adding multiple -V
-option is allowed and the more you add the more chatty \fBztest\fR
-becomes.
-.LP
-After the \fBztest\fR run completes, you should notice many ztest.*
-files lying around. Once the run completes you can safely remove these
-files. Note that you shouldn't remove these files during a run. You
-can re-use these files in your next \fBztest\fR run by using the -E
-option.

-.IP
-ztest -f / -V -T 120
-
-.SH "ENVIRONMENT VARIABLES"
-.TP
-.B "ZFS_STACK_SIZE=stacksize"
-Limit the default stack size to \fBstacksize\fR bytes for the purpose of
-detecting and debugging kernel stack overflows. For x86_64 platforms this
-value should be set as follows to simulate these platforms: \fB8192\fR
-(Linux), \fB20480\fR (Illumos), \fB16384\fR (FreeBSD).
-
-In practice you may need to set these value slightly higher because
-differences in stack usage between kernel and user space can lead to spurious
-stack overflows (especially when debugging is enabled). The specified value
-will be rounded up to a floor of PTHREAD_STACK_MIN which is the minimum stack
-required for a NULL procedure in user space.
-
-By default the stack size is limited to 256K.

-.SH NAME
-vdev_id.conf \- Configuration file for vdev_id
-.SH DESCRIPTION
-.I vdev_id.conf
-is the configuration file for
-.BR vdev_id (8).
-It controls the default behavior of
-.BR vdev_id (8)
-while it is mapping a disk device name to an alias.
-.PP
-The
-.I vdev_id.conf
-file uses a simple format consisting of a keyword followed by one or
-more values on a single line. Any line not beginning with a recognized
-keyword is ignored. Comments may optionally begin with a hash
-character.
-
-The following keywords and values are used.
-.TP
-\fIalias\fR <name> <devlink>
-Maps a device link in the /dev directory hierarchy to a new device
-name. The udev rule defining the device link must have run prior to
-.BR vdev_id (8).
-A defined alias takes precedence over a topology-derived name, but the
-two naming methods can otherwise coexist. For example, one might name
-drives in a JBOD with the sas_direct topology while naming an internal
-L2ARC device with an alias.
-
-\fIname\fR - the name of the link to the device that will by created in
-/dev/disk/by-vdev.
-
-\fIdevlink\fR - the name of the device link that has already been
-defined by udev. This may be an absolute path or the base filename.
-
-.TP
-\fIchannel\fR [pci_slot] <port> <name>
-Maps a physical path to a channel name (typically representing a single
-disk enclosure).
-
-\fIpci_slot\fR - specifies the PCI SLOT of the HBA
-hosting the disk enclosure being mapped, as found in the output of
-.BR lspci (8).
-This argument is not used in sas_switch mode.
-
-\fIport\fR - specifies the numeric identifier of the HBA or SAS switch port
-connected to the disk enclosure being mapped.
-
-\fIname\fR - specifies the name of the channel.
-
-.TP
-\fIslot\fR <old> <new> [channel]
-Maps a disk slot number as reported by the operating system to an
-alternative slot number. If the \fIchannel\fR parameter is specified
-then the mapping is only applied to slots in the named channel,
-otherwise the mapping is applied to all channels. The first-specified
-\fIslot\fR rule that can match a slot takes precedence. Therefore a
-channel-specific mapping for a given slot should generally appear before
-a generic mapping for the same slot. In this way a custom mapping may
-be applied to a particular channel and a default mapping applied to the
-others.
-
-.TP
-\fImultipath\fR <yes|no>
-Specifies whether
-.BR vdev_id (8)
-will handle only dm-multipath devices. If set to "yes" then
-.BR vdev_id (8)
-will examine the first running component disk of a dm-multipath
-device as listed by the
-.BR multipath (8)
-command to determine the physical path.
-.TP
-\fItopology\fR <sas_direct|sas_switch>
-Identifies a physical topology that governs how physical paths are
-mapped to channels.
-
-\fIsas_direct\fR - in this mode a channel is uniquely identified by
-a PCI slot and a HBA port number
-
-\fIsas_switch\fR - in this mode a channel is uniquely identified by
-a SAS switch port number
-
-.TP
-\fIphys_per_port\fR <num>
-Specifies the number of PHY devices associated with a SAS HBA port or SAS
-switch port.
-.BR vdev_id (8)
-internally uses this value to determine which HBA or switch port a
-device is connected to. The default is 4.
-
-.TP
-\fIslot\fR <bay|phy|id|lun>
-Specifies from which element of a SAS identifier the slot number is
-taken. The default is bay.
-
-\fIbay\fR - read the slot number from the bay identifier.
-
-\fIphy\fR - read the slot number from the phy identifier.
-
-\fIid\fR - use the scsi id as the slot number.
-
-\fIlun\fR - use the scsi lun as the slot number.

-\fBzfs_free_leak_on_eio\fR (int)
-.ad
-.RS 12n
-If destroy encounters an EIO while reading metadata (e.g. indirect
-blocks), space referenced by the missing metadata can not be freed.
-Normally this causes the background destroy to become "stalled", as
-it is unable to make forward progress. While in this stalled state,
-all remaining space to free from the error-encountering filesystem is
-"temporarily leaked". Set this flag to cause it to ignore the EIO,
-permanently leak the space from indirect blocks that can not be read,
-and continue to free everything else that it can.
-
-The default, "stalling" behavior is useful if the storage partially
-fails (i.e. some but not all i/os fail), and then later recovers. In
-this case, we will be able to continue pool operations while it is
-partially failed, and when it recovers, we can continue to free the
-space, with no leaks. However, note that this case is actually
-fairly rare.
-
-Typically pools either (a) fail completely (but perhaps temporarily,
-e.g. a top-level vdev going offline), or (b) have localized,
-permanent errors (e.g. disk returns the wrong data due to bit flip or
-firmware bug). In case (a), this setting does not matter because the
-pool will be suspended and the sync thread will not be able to make
-forward progress regardless. In case (b), because the error is
-permanent, the best we can do is leak the minimum amount of space,
-which is what setting this flag will do. Therefore, it is reasonable
-for this flag to normally be set, but we chose the more conservative
-approach of not setting it, so that there is no possibility of
-leaking space in the "partial temporary" failure case.

-.SH ZFS I/O SCHEDULER
-ZFS issues I/O operations to leaf vdevs to satisfy and complete I/Os.
-The I/O scheduler determines when and in what order those operations are
-issued. The I/O scheduler divides operations into five I/O classes
-prioritized in the following order: sync read, sync write, async read,
-async write, and scrub/resilver. Each queue defines the minimum and
-maximum number of concurrent operations that may be issued to the
-device. In addition, the device has an aggregate maximum,
-\fBzfs_vdev_max_active\fR. Note that the sum of the per-queue minimums
-must not exceed the aggregate maximum. If the sum of the per-queue
-maximums exceeds the aggregate maximum, then the number of active I/Os
-may reach \fBzfs_vdev_max_active\fR, in which case no further I/Os will
-be issued regardless of whether all per-queue minimums have been met.
-.sp
-For many physical devices, throughput increases with the number of
-concurrent operations, but latency typically suffers. Further, physical
-devices typically have a limit at which more concurrent operations have no
-effect on throughput or can actually cause it to decrease.
-.sp
-The scheduler selects the next operation to issue by first looking for an
-I/O class whose minimum has not been satisfied. Once all are satisfied and
-the aggregate maximum has not been hit, the scheduler looks for classes
-whose maximum has not been satisfied. Iteration through the I/O classes is
-done in the order specified above. No further operations are issued if the
-aggregate maximum number of concurrent operations has been hit or if there
-are no operations queued for an I/O class that has not hit its maximum.
-Every time an I/O is queued or an operation completes, the I/O scheduler
-looks for new operations to issue.
-.sp
-In general, smaller max_active's will lead to lower latency of synchronous
-operations. Larger max_active's may lead to higher overall throughput,
-depending on underlying storage.
-.sp
-The ratio of the queues' max_actives determines the balance of performance
-between reads, writes, and scrubs. E.g., increasing
-\fBzfs_vdev_scrub_max_active\fR will cause the scrub or resilver to complete
-more quickly, but reads and writes to have higher latency and lower throughput.
-.sp
-All I/O classes have a fixed maximum number of outstanding operations
-except for the async write class. Asynchronous writes represent the data
-that is committed to stable storage during the syncing stage for
-transaction groups. Transaction groups enter the syncing state
-periodically so the number of queued async writes will quickly burst up
-and then bleed down to zero. Rather than servicing them as quickly as
-possible, the I/O scheduler changes the maximum number of active async
-write I/Os according to the amount of dirty data in the pool. Since
-both throughput and latency typically increase with the number of
-concurrent operations issued to physical devices, reducing the
-burstiness in the number of concurrent operations also stabilizes the
-response time of operations from other -- and in particular synchronous
--- queues. In broad strokes, the I/O scheduler will issue more
-concurrent operations from the async write queue as there's more dirty
-data in the pool.
-.sp
-Async Writes
-.sp
-The number of concurrent operations issued for the async write I/O class
-follows a piece-wise linear function defined by a few adjustable points.
-.nf
-
- | o---------| <-- zfs_vdev_async_write_max_active
- ^ | /^ |
- | | / | |
-active | / | |
- I/O | / | |
-count | / | |

- | |
- | `-- zfs_vdev_async_write_active_max_dirty_percent
- `--------- zfs_vdev_async_write_active_min_dirty_percent
-
-.fi
-Until the amount of dirty data exceeds a minimum percentage of the dirty
-data allowed in the pool, the I/O scheduler will limit the number of
-concurrent operations to the minimum. As that threshold is crossed, the
-number of concurrent operations issued increases linearly to the maximum at
-the specified maximum percentage of the dirty data allowed in the pool.
-.sp
-Ideally, the amount of dirty data on a busy pool will stay in the sloped
-part of the function between \fBzfs_vdev_async_write_active_min_dirty_percent\fR
-and \fBzfs_vdev_async_write_active_max_dirty_percent\fR. If it exceeds the
-maximum percentage, this indicates that the rate of incoming data is
-greater than the rate that the backend storage can handle. In this case, we
-must further throttle incoming writes, as described in the next section.
-
-.SH ZFS TRANSACTION DELAY
-We delay transactions when we've determined that the backend storage
-isn't able to accommodate the rate of incoming writes.
-.sp
-If there is already a transaction waiting, we delay relative to when
-that transaction will finish waiting. This way the calculated delay time
-is independent of the number of threads concurrently executing
-transactions.
-.sp
-If we are the only waiter, wait relative to when the transaction
-started, rather than the current time. This credits the transaction for
-"time already served", e.g. reading indirect blocks.
-.sp
-The minimum time for a transaction to take is calculated as:
-.nf
- min_time = zfs_delay_scale * (dirty - min) / (max - dirty)
- min_time is then capped at 100 milliseconds.
-.fi
-.sp
-The delay has two degrees of freedom that can be adjusted via tunables. The
-percentage of dirty data at which we start to delay is defined by
-\fBzfs_delay_min_dirty_percent\fR. This should typically be at or above
-\fBzfs_vdev_async_write_active_max_dirty_percent\fR so that we only start to
-delay after writing at full speed has failed to keep up with the incoming write
-rate. The scale of the curve is defined by \fBzfs_delay_scale\fR. Roughly speaking,
-this variable determines the amount of delay at the midpoint of the curve.

-.fi
-.sp
-Note that since the delay is added to the outstanding time remaining on the
-most recent transaction, the delay is effectively the inverse of IOPS.
-Here the midpoint of 500us translates to 2000 IOPS. The shape of the curve
-was chosen such that small changes in the amount of accumulated dirty data
-in the first 3/4 of the curve yield relatively small differences in the
-amount of delay.
-.sp
-The effects can be easier to understand when the amount of delay is
-represented on a log scale:
-.sp
-.nf

- +--------------------------------------------------------------+
- 0% <- zfs_dirty_data_max -> 100%
-.fi
-.sp
-Note here that only as the amount of dirty data approaches its limit does
-the delay start to increase rapidly. The goal of a properly tuned system
-should be to keep the amount of dirty data out of that range by first
-ensuring that the appropriate limits are set for the I/O scheduler to reach
-optimal throughput on the backend storage, and then by changing the value
-of \fBzfs_delay_scale\fR to increase the steepness of the curve.

-.TH ZPOOL-FEATURES 5 "Aug 27, 2013"
-.SH NAME
-zpool\-features \- ZFS pool feature descriptions
-.SH DESCRIPTION
-.sp
-.LP
-ZFS pool on\-disk format versions are specified via "features" which replace
-the old on\-disk format numbers (the last supported on\-disk format number is
-28). To enable a feature on a pool use the \fBupgrade\fR subcommand of the
-\fBzpool\fR(8) command, or set the \fBfeature@\fR\fIfeature_name\fR property
-to \fBenabled\fR.
-.sp
-.LP
-The pool format does not affect file system version compatibility or the ability
-to send file systems between pools.
-.sp
-.LP
-Since most features can be enabled independently of each other the on\-disk
-format of the pool is specified by the set of all features marked as
-\fBactive\fR on the pool. If the pool was created by another software version
-this set may include unsupported features.
-.SS "Identifying features"
-.sp
-.LP
-Every feature has a guid of the form \fIcom.example:feature_name\fR. The reverse
-DNS name ensures that the feature's guid is unique across all ZFS
-implementations. When unsupported features are encountered on a pool they will
-be identified by their guids. Refer to the documentation for the ZFS
-implementation that created the pool for information about those features.
-.sp
-.LP
-Each supported feature also has a short name. By convention a feature's short
-name is the portion of its guid which follows the ':' (e.g.
-\fIcom.example:feature_name\fR would have the short name \fIfeature_name\fR),
-however a feature's short name may differ across ZFS implementations if
-following the convention would result in name conflicts.
-.SS "Feature states"
-.sp
-.LP
-Features can be in one of three states:
-.sp
-.ne 2
-.na
-\fB\fBactive\fR\fR
-.ad
-.RS 12n
-This feature's on\-disk format changes are in effect on the pool. Support for
-this feature is required to import the pool in read\-write mode. If this
-feature is not read-only compatible, support is also required to import the pool
-in read\-only mode (see "Read\-only compatibility").
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fBenabled\fR\fR
-.ad
-.RS 12n
-An administrator has marked this feature as enabled on the pool, but the
-feature's on\-disk format changes have not been made yet. The pool can still be
-imported by software that does not support this feature, but changes may be made
-to the on\-disk format at any time which will move the feature to the
-\fBactive\fR state. Some features may support returning to the \fBenabled\fR
-state after becoming \fBactive\fR. See feature\-specific documentation for
-details.
-.RE
-
-.sp
-.ne 2
-.na
-\fBdisabled\fR
-.ad
-.RS 12n
-This feature's on\-disk format changes have not been made and will not be made
-unless an administrator moves the feature to the \fBenabled\fR state. Features
-cannot be disabled once they have been enabled.
-.RE
-
-.sp
-.LP
-The state of supported features is exposed through pool properties of the form
-\fIfeature@short_name\fR.
-.SS "Read\-only compatibility"
-.sp
-.LP
-Some features may make on\-disk format changes that do not interfere with other
-software's ability to read from the pool. These features are referred to as
-"read\-only compatible". If all unsupported features on a pool are read\-only
-compatible, the pool can be imported in read\-only mode by setting the
-\fBreadonly\fR property during import (see \fBzpool\fR(8) for details on
-importing pools).
-.SS "Unsupported features"
-.sp
-.LP
-For each unsupported feature enabled on an imported pool a pool property
-named \fIunsupported@feature_guid\fR will indicate why the import was allowed
-despite the unsupported feature. Possible values for this property are:
-
-.sp
-.ne 2
-.na
-\fB\fBinactive\fR\fR
-.ad
-.RS 12n
-The feature is in the \fBenabled\fR state and therefore the pool's on\-disk
-format is still compatible with software that does not support this feature.
-.RE
-
-.sp
-.ne 2
-.na
-\fB\fBreadonly\fR\fR
-.ad
-.RS 12n
-The feature is read\-only compatible and the pool has been imported in
-read\-only mode.
-.RE
-
-.SS "Feature dependencies"
-.sp
-.LP
-Some features depend on other features being enabled in order to function
-properly. Enabling a feature will automatically enable any features it
-depends on.
-.SH FEATURES
-.sp
-.LP
-The following features are supported on this system:
-.sp

-.ad
-.RS 4n
-.TS
-l l .
-GUID com.delphix:async_destroy
-READ\-ONLY COMPATIBLE yes
-DEPENDENCIES none
-.TE
-
-Destroying a file system requires traversing all of its data in order to
-return its used space to the pool. Without \fBasync_destroy\fR the file system
-is not fully removed until all space has been reclaimed. If the destroy
-operation is interrupted by a reboot or power outage the next attempt to open
-the pool will need to complete the destroy operation synchronously.
-
-When \fBasync_destroy\fR is enabled the file system's data will be reclaimed
-by a background process, allowing the destroy operation to complete without
-traversing the entire file system. The background process is able to resume
-interrupted destroys after the pool has been opened, eliminating the need
-to finish interrupted destroys as part of the open operation. The amount
-of space remaining to be reclaimed by the background process is available
-through the \fBfreeing\fR property.

-.ad
-.RS 4n
-.TS
-l l .
-GUID com.delphix:empty_bpobj
-READ\-ONLY COMPATIBLE yes
-DEPENDENCIES none
-.TE
-
-This feature increases the performance of creating and using a large
-number of snapshots of a single filesystem or volume, and also reduces
-the disk space required.
-
-When there are many snapshots, each snapshot uses many Block Pointer
-Objects (bpobj's) to track blocks associated with that snapshot.
-However, in common use cases, most of these bpobj's are empty. This
-feature allows us to create each bpobj on-demand, thus eliminating the
-empty bpobjs.
-
-This feature is \fBactive\fR while there are any filesystems, volumes,
-or snapshots which were created after enabling this feature.
-.RE

-DEPENDENCIES extensible_dataset
-.TE
-
-This feature enables filesystem and snapshot limits. These limits can be used
-to control how many filesystems and/or snapshots can be created at the point in
-the tree on which the limits are set.
-
-This feature is \fBactive\fR once either of the limit properties has been
-set on a dataset. Once activated the feature is never deactivated.

-GUID org.illumos:lz4_compress
-READ\-ONLY COMPATIBLE no
-DEPENDENCIES none
-.TE
-
-\fBlz4\fR is a high-performance real-time compression algorithm that
-features significantly faster compression and decompression as well as a
-higher compression ratio than the older \fBlzjb\fR compression.
-Typically, \fBlz4\fR compression is approximately 50% faster on
-compressible data and 200% faster on incompressible data than
-\fBlzjb\fR. It is also approximately 80% faster on decompression, while
-giving approximately 10% better compression ratio.
-
-When the \fBlz4_compress\fR feature is set to \fBenabled\fR, the
-administrator can turn on \fBlz4\fR compression on any dataset on the
-pool using the \fBzfs\fR(8) command. Please note that doing so will
-immediately activate the \fBlz4_compress\fR feature on the underlying
-pool using the \fBzfs\fR(1M) command. Also, all newly written metadata
-will be compressed with \fBlz4\fR algorithm. Since this feature is not
-read-only compatible, this operation will render the pool unimportable
-on systems without support for the \fBlz4_compress\fR feature. Booting
-off of \fBlz4\fR-compressed root pools is supported.
-
-This feature becomes \fBactive\fR as soon as it is enabled and will
-never return to being \fBenabled\fB.

-
-This features allows ZFS to maintain more information about how free space
-is organized within the pool. If this feature is \fBenabled\fR, ZFS will
-set this feature to \fBactive\fR when a new space map object is created or
-an existing space map is upgraded to the new format. Once the feature is
-\fBactive\fR, it will remain in that state until the pool is destroyed.

-READ\-ONLY COMPATIBLE no
-DEPENDENCIES enabled_txg
-.TE
-
-This feature improves performance of incremental sends ("zfs send -i")
-and receives for objects with many holes. The most common case of
-hole-filled objects is zvols.
-
-An incremental send stream from snapshot \fBA\fR to snapshot \fBB\fR
-contains information about every block that changed between \fBA\fR and
-\fBB\fR. Blocks which did not change between those snapshots can be
-identified and omitted from the stream using a piece of metadata called
-the 'block birth time', but birth times are not recorded for holes (blocks
-filled only with zeroes). Since holes created after \fBA\fR cannot be
-distinguished from holes created before \fBA\fR, information about every
-hole in the entire filesystem or zvol is included in the send stream.
-
-For workloads where holes are rare this is not a problem. However, when
-incrementally replicating filesystems or zvols with many holes (for
-example a zvol formatted with another filesystem) a lot of time will
-be spent sending and receiving unnecessary information about holes that
-already exist on the receiving side.
-
-Once the \fBhole_birth\fR feature has been enabled the block birth times
-of all new holes will be recorded. Incremental sends between snapshots
-created after this feature is enabled will use this new metadata to avoid
-sending information about holes that already exist on the receiving side.
-
-This feature becomes \fBactive\fR as soon as it is enabled and will
-never return to being \fBenabled\fB.

-
-This feature improves the performance and compression ratio of
-highly-compressible blocks. Blocks whose contents can compress to 112 bytes
-or smaller can take advantage of this feature.
-
-When this feature is enabled, the contents of highly-compressible blocks are
-stored in the block "pointer" itself (a misnomer in this case, as it contains
-the compresseed data, rather than a pointer to its location on disk). Thus
-the space of the block (one sector, typically 512 bytes or 4KB) is saved,
-and no additional i/o is needed to read and write the data block.

-
-.SH SYNOPSIS
-.LP
-.BI "fsck.zfs [" "options" "] <" "dataset" ">"
-
-.SH DESCRIPTION
-.LP
-\fBfsck.zfs\fR is a shell stub that does nothing and always returns
-true. It is installed by ZoL because some Linux distributions expect
-a fsck helper for all filesystems.
-
-.SH OPTIONS
-.HP
-All \fIoptions\fR and the \fIdataset\fR are ignored.
-
-.SH "NOTES"
-.LP
-ZFS datasets are checked by running \fBzpool scrub\fR on the
-containing pool. An individual ZFS dataset is never checked
-independently of its pool, which is unlike a regular filesystem.
-
-.SH "BUGS"
-.LP
-On some systems, if the \fIdataset\fR is in a degraded pool, then it
-might be appropriate for \fBfsck.zfs\fR to return exit code 4 to
-indicate an uncorrected filesystem error.
-.LP
-Similarly, if the \fIdataset\fR is in a faulted pool and has a legacy
-/etc/fstab record, then \fBfsck.zfs\fR should return exit code 8 to
-indicate a fatal operational error.

-
-.SH DESCRIPTION
-.BR mount.zfs
-is part of the zfsutils package for Linux. It is a helper program that
-is usually invoked by the
-.BR mount (8)
-or
-.BR zfs (8)
-commands to mount a ZFS dataset.
-
-All
-.I options
-are handled according to the FILESYSTEM INDEPENDENT MOUNT OPTIONS
-section in the
-.BR mount (8)
-manual, except for those described below.
-
-The
-.I dataset
-parameter is a ZFS filesystem name, as output by the
-.B "zfs list -H -o name
-command. This parameter never has a leading slash character and is
-not a device name.
-
-The
-.I mountpoint
-parameter is the path name of a directory.

-.SH SYNOPSIS
-.LP
-.nf
-\fBvdev_id\fR <-d dev> [-c config_file] [-g sas_direct|sas_switch]
- [-m] [-p phys_per_port]
-\fBvdev_id\fR -h
-.fi
-.SH DESCRIPTION
-The \fBvdev_id\fR command is a udev helper which parses the file
-.BR /etc/zfs/vdev_id.conf (5)
-to map a physical path in a storage topology to a channel name. The
-channel name is combined with a disk enclosure slot number to create an
-alias that reflects the physical location of the drive. This is
-particularly helpful when it comes to tasks like replacing failed
-drives. Slot numbers may also be re-mapped in case the default
-numbering is unsatisfactory. The drive aliases will be created as
-symbolic links in /dev/disk/by-vdev.
-
-The currently supported topologies are sas_direct and sas_switch. A
-multipath mode is supported in which dm-mpath devices are handled by
-examining the first-listed running component disk as reported by the
-.BR multipath (8)
-command. In multipath mode the configuration file should contain a
-channel definition with the same name for each path to a given
-enclosure.
-
-.BR vdev_id
-also supports creating aliases based on existing udev links in the /dev
-hierarchy using the \fIalias\fR configuration file keyword. See the
-.BR vdev_id.conf (5)
-man page for details.
-
-.SH OPTIONS
-.TP
-\fB\-c\fR <config_file>
-Specifies the path to an alternate configuration file. The default is
-/etc/zfs/vdev_id.conf.
-.TP
-\fB\-d\fR <device>
-This is the only mandatory argument. Specifies the name of a device
-in /dev, i.e. "sda".
-.TP
-\fB\-g\fR <sas_direct|sas_switch>
-Identifies a physical topology that governs how physical paths are
-mapped to channels.
-
-\fIsas_direct\fR - in this mode a channel is uniquely identified by
-a PCI slot and a HBA port number
-
-\fIsas_switch\fR - in this mode a channel is uniquely identified by
-a SAS switch port number
-.TP
-\fB\-m\fR
-Specifies that
-.BR vdev_id (8)
-will handle only dm-multipath devices. If set to "yes" then
-.BR vdev_id (8)
-will examine the first running component disk of a dm-multipath
-device as listed by the
-.BR multipath (8)
-command to determine the physical path.
-.TP
-\fB\-p\fR <phys_per_port>
-Specifies the number of PHY devices associated with a SAS HBA port or SAS
-switch port.
-.BR vdev_id (8)
-internally uses this value to determine which HBA or switch port a
-device is connected to. The default is 4.
-.TP

-.SH "DESCRIPTION"
-The \fBzdb\fR utility displays information about a ZFS pool useful for
-debugging and performs some amount of consistency checking. It is a not a
-general purpose tool and options (and facilities) may change. This is neither
-a fsck(8) nor an fsdb(8) utility.
-
-.P
-The output of this command in general reflects the on-disk structure of a ZFS
-pool, and is inherently unstable. The precise output of most invocations is
-not documented, a knowledge of ZFS internals is assumed.
-
-.P
-If the \fIdataset\fR argument does not contain any \fB/\fR or \fB@\fR
-characters, it is interpreted as a pool name. The root dataset can be
-specified as \fIpool\fB/\fR (pool name followed by a slash).
-
-.P
-When operating on an imported and active pool it is possible, though unlikely,
-that zdb may interpret inconsistent pool data and behave erratically.

-
-.SH ZEVENTS
-.PP
-A zevent is comprised of a list of nvpairs (name/value pairs). Each zevent
-contains an EID (Event IDentifier) that uniquely identifies it throughout
-the lifetime of the loaded ZFS kernel module; this EID is a monotonically
-increasing integer that resets to 1 each time the kernel module is loaded.
-Each zevent also contains a class string that identifies the type of event.
-For brevity, a subclass string is defined that omits the leading components
-of the class string. Additional nvpairs exist to provide event details.
-.PP
-The kernel maintains a list of recent zevents that can be viewed (along with
-their associated lists of nvpairs) using the "\fBzpool events \-v\fR" command.
-
-.SH CONFIGURATION
-.PP
-ZEDLETs to be invoked in response to zevents are located in the
-\fIenabled-zedlets\fR directory. These can be symlinked or copied from the
-\fIinstalled-zedlets\fR directory; symlinks allow for automatic updates
-from the installed ZEDLETs, whereas copies preserve local modifications.
-As a security measure, ZEDLETs must be owned by root. They must have
-execute permissions for the user, but they must not have write permissions
-for group or other. Dotfiles are ignored.
-.PP
-ZEDLETs are named after the zevent class for which they should be invoked.
-In particular, a ZEDLET will be invoked for a given zevent if either its
-class or subclass string is a prefix of its filename (and is followed by
-a non-alphabetic character). As a special case, the prefix "all" matches
-all zevents. Multiple ZEDLETs may be invoked for a given zevent.
-
-.SH ZEDLETS
-.PP
-ZEDLETs are executables invoked by the ZED in response to a given zevent.
-They should be written under the presumption they can be invoked concurrently,
-and they should use appropriate locking to access any shared resources.
-Common variables used by ZEDLETs can be stored in the default rc file which
-is sourced by scripts; these variables should be prefixed with "ZED_".
-.PP
-The zevent nvpairs are passed to ZEDLETs as environment variables.
-Each nvpair name is converted to an environment variable in the following
-manner: 1) it is prefixed with "ZEVENT_", 2) it is converted to uppercase,
-and 3) each non-alphanumeric character is converted to an underscore.
-Some additional environment variables have been defined to present certain
-nvpair values in a more convenient form. An incomplete list of zevent
-environment variables is as follows:
-.TP
-.B
-ZEVENT_EID
-The Event IDentifier.
-.TP
-.B
-ZEVENT_CLASS
-The zevent class string.
-.TP
-.B
-ZEVENT_SUBCLASS
-The zevent subclass string.
-.TP
-.B
-ZEVENT_TIME
-The time at which the zevent was posted as
-"\fIseconds\fR\ \fInanoseconds\fR" since the Epoch.
-.TP
-.B
-ZEVENT_TIME_SECS
-The \fIseconds\fR component of ZEVENT_TIME.
-.TP
-.B
-ZEVENT_TIME_NSECS
-The \fInanoseconds\fR component of ZEVENT_TIME.
-.TP
-.B
-ZEVENT_TIME_STRING
-An almost-RFC3339-compliant string for ZEVENT_TIME.
-.PP
-Additionally, the following ZED & ZFS variables are defined:
-.TP
-.B
-ZED_PID
-The daemon's process ID.
-.TP
-.B
-ZED_ZEDLET_DIR
-The daemon's current \fIenabled-zedlets\fR directory.
-.TP
-.B
-ZFS_ALIAS
-The ZFS alias (\fIname-version-release\fR) string used to build the daemon.
-.TP
-.B
-ZFS_VERSION
-The ZFS version used to build the daemon.
-.TP
-.B
-ZFS_RELEASE
-The ZFS release used to build the daemon.
-.PP
-ZEDLETs may need to call other ZFS commands. The installation paths of
-the following executables are defined: \fBZDB\fR, \fBZED\fR, \fBZFS\fR,
-\fBZINJECT\fR, and \fBZPOOL\fR. These variables can be overridden in the
-rc file if needed.
-
-.SH FILES
-.\" .TP
-.\" @sysconfdir@/zfs/zed.conf
-.\" The default configuration file for the daemon.
-.TP
-.I @sysconfdir@/zfs/zed.d
-The default directory for enabled ZEDLETs.

-.TP
-.I @libexecdir@/zfs/zed.d

-.TP
-.I @runstatedir@/zed.pid
-The default file containing the daemon's process ID.
-.TP
-.I @runstatedir@/zed.state

-
-.SH SIGNALS
-.TP
-.B HUP
-Reconfigure the daemon and rescan the directory for enabled ZEDLETs.
-.TP
-.B TERM
-Terminate the daemon.
-
-.SH NOTES
-.PP
-\fBZED\fR requires root privileges.
-.\" Do not taunt zed.
-
-.SH BUGS
-.PP
-Events are processed synchronously by a single thread. This can delay the
-processing of simultaneous zevents.
-.PP
-There is no maximum timeout for ZEDLET execution. Consequently, a misbehaving
-ZEDLET can delay the processing of subsequent zevents.
-.PP
-The ownership and permissions of the \fIenabled-zedlets\fR directory (along
-with all parent directories) are not checked. If any of these directories
-are improperly owned or permissioned, an unprivileged user could insert a
-ZEDLET to be executed as root. The requirement that ZEDLETs be owned by
-root mitigates this to some extent.
-.PP
-ZEDLETs are unable to return state/status information to the kernel.
-.PP
-Some zevent nvpair types are not handled. These are denoted by zevent
-environment variables having a "_NOT_IMPLEMENTED_" value.
-.PP
-Internationalization support via gettext has not been added.
-.PP
-The configuration file is not yet implemented.
-.PP
-The diagnosis engine is not yet implemented.

-.SH DESCRIPTION
-.LP
-The \fBzfs\fR command configures \fBZFS\fR datasets within a \fBZFS\fR storage pool, as described in \fBzpool\fR(8). A dataset is identified by a unique path within the \fBZFS\fR namespace. For example:
-.sp
-.in +2
-.nf
-pool/{filesystem,volume,snapshot}
-.fi
-.in -2
-.sp
-
-.sp
-.LP
-where the maximum length of a dataset name is \fBMAXNAMELEN\fR (256 bytes).
-.sp
-.LP
-A dataset can be one of the following:
-.sp
-.ne 2
-.mk
-.na
-\fB\fIfile system\fR\fR
-.ad
-.sp .6
-.RS 4n
-A \fBZFS\fR dataset of type \fBfilesystem\fR can be mounted within the standard system namespace and behaves like other file systems. While \fBZFS\fR file systems are designed to be \fBPOSIX\fR compliant, known issues exist that prevent compliance in some cases. Applications that depend on standards conformance might fail due to nonstandard behavior when checking file system free space.
-.RE
-
-.sp
-.ne 2
-.mk
-.na
-\fB\fIvolume\fR\fR
-.ad
-.sp .6
-.RS 4n
-A logical volume exported as a raw or block device. This type of dataset should only be used under special circumstances. File systems are typically used in most environments.
-.RE

-.sp

-\fB\fIsnapshot\fR\fR
-.ad
-.sp .6
-.RS 4n

-.RE
-
-.SS "ZFS File System Hierarchy"
-.LP
-A \fBZFS\fR storage pool is a logical collection of devices that provide space for datasets. A storage pool is also the root of the \fBZFS\fR file system hierarchy.
-.sp
-.LP
-The root of the pool can be accessed as a file system, such as mounting and unmounting, taking snapshots, and setting properties. The physical storage characteristics, however, are managed by the \fBzpool\fR(8) command.
-.sp
-.LP
-See \fBzpool\fR(8) for more information on creating and administering pools.
-.SS "Snapshots"
-.LP
-A snapshot is a read-only copy of a file system or volume. Snapshots can be created extremely quickly, and initially consume no additional space within the pool. As data within the active dataset changes, the snapshot consumes more data than would otherwise be shared with the active dataset.
-.sp
-.LP
-Snapshots can have arbitrary names. Snapshots of volumes can be cloned or rolled back. Visibility is determined by the \fBsnapdev\fR property of the parent volume.
-.sp
-.LP
-File system snapshots can be accessed under the \fB\&.zfs/snapshot\fR directory in the root of the file system. Snapshots are automatically mounted on demand and may be unmounted at regular intervals. The visibility of the \fB\&.zfs\fR directory can be controlled by the \fBsnapdir\fR property.
-.SS "Bookmarks"
-.LP
-A bookmark is like a snapshot, a read-only copy of a file system or volume. Bookmarks can be created extremely quickly, compared to snapshots, and they consume no additional space within the pool. Bookmarks can also have arbitrary names, much like snapshots.
-.sp
-.LP
-Unlike snapshots, bookmarks can not be accessed through the filesystem in any way. From a storage standpoint a bookmark just provides a way to reference when a snapshot was created as a distinct object. Bookmarks are initially tied to a snapshot, not the filesystem/volume, and they will survive if the snapshot itself is destroyed. Since they are very light weight there's little incentive to destroy them.
-.SS "Clones"
-.LP
-A clone is a writable volume or file system whose initial contents are the same as another dataset. As with snapshots, creating a clone is nearly instantaneous, and initially consumes no additional space.
-.sp
-.LP
-Clones can only be created from a snapshot. When a snapshot is cloned, it creates an implicit dependency between the parent and child. Even though the clone is created somewhere else in the dataset hierarchy, the original snapshot cannot be destroyed as long as a clone exists. The \fBorigin\fR property exposes this dependency, and the \fBdestroy\fR command lists any such dependencies, if they exist.
-.sp
-.LP
-The clone parent-child dependency relationship can be reversed by using the \fBpromote\fR subcommand. This causes the "origin" file system to become a clone of the specified file system, which makes it possible to destroy the file system that the clone was created from.
-.SS "Mount Points"
-.LP
-Creating a \fBZFS\fR file system is a simple operation, so the number of file systems per system is likely to be numerous. To cope with this, \fBZFS\fR automatically manages mounting and unmounting file systems without the need to edit the \fB/etc/fstab\fR file. All automatically managed file systems are mounted by \fBZFS\fR at boot time.
-.sp
-.LP
-By default, file systems are mounted under \fB/\fIpath\fR\fR, where \fIpath\fR is the name of the file system in the \fBZFS\fR namespace. Directories are created and destroyed as needed.
-.sp
-.LP
-A file system can also have a mount point set in the \fBmountpoint\fR property. This directory is created as needed, and \fBZFS\fR automatically mounts the file system when the \fBzfs mount -a\fR command is invoked (without editing \fB/etc/fstab\fR). The \fBmountpoint\fR property can be inherited, so if \fBpool/home\fR has a mount point of \fB/export/stuff\fR, then \fBpool/home/user\fR automatically inherits a mount point of \fB/export/stuff/user\fR.
-.sp
-.LP
-A file system \fBmountpoint\fR property of \fBnone\fR prevents the file system from being mounted.
-.sp
-.LP
-If needed, \fBZFS\fR file systems can also be managed with traditional tools (\fBmount\fR, \fBumount\fR, \fB/etc/fstab\fR). If a file system's mount point is set to \fBlegacy\fR, \fBZFS\fR makes no attempt to manage the file system, and the administrator is responsible for mounting and unmounting the file system.
-.SS "Deduplication"
-.LP
-Deduplication is the process for removing redundant data at the block-level, reducing the total amount of data stored. If a file system has the \fBdedup\fR property enabled, duplicate data blocks are removed synchronously. The result is that only unique data is stored and common components are shared among files.
-.sp
-\fBWARNING: DO NOT ENABLE DEDUPLICATION UNLESS YOU NEED IT AND KNOW EXACTLY WHAT YOU ARE DOING!\fR
-.sp
-Deduplicating data is a very resource-intensive operation. It is generally recommended that you have \fIat least\fR 1.25 GB of RAM per 1 TB of storage when you enable deduplication. But calculating the exact requirenments is a somewhat complicated affair. Please see the \fBOracle Dedup Guide\fR for more information..
-.sp
-Enabling deduplication on an improperly-designed system will result in extreme performance issues (extremely slow filesystem and snapshot deletions etc.) and can potentially lead to data loss (i.e. unimportable pool due to memory exhaustion) if your system is not built for this purpose. Deduplication affects the processing power (CPU), disks (and the controller) as well as primary (real) memory.
-.sp
-Before creating a pool with deduplication enabled, ensure that you have planned your hardware requirements appropriately and implemented appropriate recovery practices, such as regular backups.
-.sp
-Unless necessary, deduplication should NOT be enabled on a system. Instead, consider using \fIcompression=lz4\fR, as a less resource-intensive alternative.
-.SS "Native Properties"
-.LP
-Properties are divided into two types, native properties and user-defined (or "user") properties. Native properties either export internal statistics or control \fBZFS\fR behavior. In addition, native properties are either editable or read-only. User properties have no effect on \fBZFS\fR behavior, but you can use them to annotate datasets in a way that is meaningful in your environment. For more information about user properties, see the "User Properties" section, below.
-.sp
-.LP
-Every dataset has a set of properties that export statistics about the dataset as well as control various behaviors. Properties are inherited from the parent unless overridden by the child. Some properties apply only to certain types of datasets (file systems, volumes, or snapshots).
-.sp
-.LP
-The values of numeric properties can be specified using human-readable suffixes (for example, \fBk\fR, \fBKB\fR, \fBM\fR, \fBGb\fR, and so forth, up to \fBZ\fR for zettabyte). The following are all valid (and equal) specifications:
-.sp
-.in +2
-.nf
-1536M, 1.5g, 1.50GB
-.fi
-.in -2
-.sp
-
-.sp
-.LP
-The values of non-numeric properties are case sensitive and must be lowercase, except for \fBmountpoint\fR, \fBsharenfs\fR, and \fBsharesmb\fR.
-.sp
-.LP
-The following native properties consist of read-only statistics about the dataset. These properties can be neither set, nor inherited. Native properties apply to all dataset types unless otherwise noted.

-.sp
-When snapshots (see the "Snapshots" section) are created, their space is initially shared between the snapshot and the file system, and possibly with previous snapshots.

-Controls how \fBACL\fR entries are inherited when files and directories are created. A file system with an \fBaclinherit\fR property of \fBdiscard\fR does not inherit any \fBACL\fR entries.

-The reservation is kept equal to the volume's logical size to prevent unexpected behavior for consumers. Without the reservation, the volume could run out of space, resulting in undefined behavior or data corruption, depending on how the volume is used. These effects can also occur when the volume size is changed while it is in use (particularly when shrinking the size). Extreme care should be used when adjusting the volume size.

-Though not recommended, a "sparse volume" (also known as "thin provisioning") can be created by specifying the \fB-s\fR option to the \fBzfs create -V\fR command, or by changing the reservation after the volume has been created.

-System attribute based xattrs may be enabled by setting the value to \fBsa\fR.

-.SS "Temporary Mount Point Properties"
-.LP
-When a file system is mounted, either through \fBmount\fR(8) for legacy mounts or the \fBzfs mount\fR command for normal file systems, its mount options are set according to its properties. The correlation between properties and mount options is as follows:
-.sp
-.in +2
-.nf
- PROPERTY MOUNT OPTION
- devices devices/nodevices
- exec exec/noexec
- readonly ro/rw
- setuid setuid/nosetuid
- xattr xattr/noxattr

- relatime relatime/norelatime
- nbmand nbmand/nonbmand
-.fi
-.in -2
-.sp
-
-.sp
-.LP
-In addition, these options can be set on a per-mount basis using the \fB-o\fR option, without affecting the property that is stored on disk. The values specified on the command line override the values stored in the dataset. The \fB-nosuid\fR option is an alias for \fBnodevices,nosetuid\fR. These properties are reported as "temporary" by the \fBzfs get\fR command. If the properties are changed while the dataset is mounted, the new setting overrides any temporary settings.
-.SS "User Properties"
-.LP
-In addition to the standard native properties, \fBZFS\fR supports arbitrary user properties. User properties have no effect on \fBZFS\fR behavior, but applications or administrators can use them to annotate datasets (file systems, volumes, and snapshots).
-.sp
-.LP
-User property names must contain a colon (\fB:\fR) character to distinguish them from native properties. They may contain lowercase letters, numbers, and the following punctuation characters: colon (\fB:\fR), dash (\fB-\fR), period (\fB\&.\fR), and underscore (\fB_\fR). The expected convention is that the property name is divided into two portions such as \fImodule\fR\fB:\fR\fIproperty\fR, but this namespace is not enforced by \fBZFS\fR. User property names can be at most 256 characters, and cannot begin with a dash (\fB-\fR).
-.sp
-.LP
-When making programmatic use of user properties, it is strongly suggested to use a reversed \fBDNS\fR domain name for the \fImodule\fR component of property names to reduce the chance that two independently-developed packages use the same property name for different purposes. For example, property names beginning with \fBcom.sun\fR. are reserved for use by Oracle Corporation (which acquired Sun Microsystems).
-.sp
-.LP
-The values of user properties are arbitrary strings, are always inherited, and are never validated. All of the commands that operate on properties (\fBzfs list\fR, \fBzfs get\fR, \fBzfs set\fR, and so forth) can be used to manipulate both native properties and user properties.

-.SH DESCRIPTION
-.sp
-.LP
-The \fBzpool\fR command configures \fBZFS\fR storage pools. A storage pool is a collection of devices that provides physical storage and data replication for \fBZFS\fR datasets.
-.sp
-.LP
-All datasets within a storage pool share the same space. See \fBzfs\fR(8) for information on managing datasets.
-.SS "Virtual Devices (\fBvdev\fRs)"
-.sp
-.LP
-A "virtual device" describes a single device or a collection of devices organized according to certain performance and fault characteristics. The following virtual devices are supported:
-.sp
-.ne 2
-.mk
-.na
-\fB\fBdisk\fR\fR
-.ad
-.RS 10n
-.rt
-A block device, typically located under \fB/dev\fR. \fBZFS\fR can use individual partitions, though the recommended mode of operation is to use whole disks. A disk can be specified by a full path, or it can be a shorthand name (the relative portion of the path under "/dev"). For example, "sda" is equivalent to "/dev/sda". A whole disk can be specified by omitting the partition designation. When given a whole disk, \fBZFS\fR automatically labels the disk, if necessary.
-.RE
-
-.sp
-.ne 2
-.mk
-.na
-\fB\fBfile\fR\fR
-.ad
-.RS 10n
-.rt
-A regular file. The use of files as a backing store is strongly discouraged. It is designed primarily for experimental purposes, as the fault tolerance of a file is only as good as the file system of which it is a part. A file must be specified by a full path.
-.RE
-
-.sp
-.ne 2
-.mk
-.na
-\fB\fBmirror\fR\fR
-.ad
-.RS 10n
-.rt
-A mirror of two or more devices. Data is replicated in an identical fashion across all components of a mirror. A mirror with \fIN\fR disks of size \fIX\fR can hold \fIX\fR bytes and can withstand (\fIN-1\fR) devices failing before data integrity is compromised.

-.br

-\fB\fBraidz2\fR\fR
-.ad
-.br

-\fB\fBraidz3\fR\fR
-.ad
-.RS 10n
-.rt
-A variation on \fBRAID-5\fR that allows for better distribution of parity and eliminates the "\fBRAID-5\fR write hole" (in which data and parity become inconsistent after a power loss). Data and parity is striped across all disks within a \fBraidz\fR group.

-A pool can have any number of virtual devices at the top of the configuration (known as "root vdevs"). Data is dynamically distributed across all top-level devices to balance data among devices. As new virtual devices are added, \fBZFS\fR automatically places data on the newly available devices.

-.SS "Device Failure and Recovery"
-.sp
-.LP
-\fBZFS\fR supports a rich set of mechanisms for handling device failure and data corruption. All metadata and data is checksummed, and \fBZFS\fR automatically repairs bad data from a good copy when corruption is detected.
-.sp
-.LP
-In order to take advantage of these features, a pool must make use of some form of redundancy, using either mirrored or \fBraidz\fR groups. While \fBZFS\fR supports running in a non-redundant configuration, where each root vdev is simply a disk or file, this is strongly discouraged. A single case of bit corruption can render some or all of your data unavailable.
-.sp
-.LP
-A pool's health status is described by one of three states: online, degraded, or faulted. An online pool has all devices operating normally. A degraded pool is one in which one or more devices have failed, but the data is still available due to a redundant configuration. A faulted pool has corrupted metadata, or one or more faulted devices, and insufficient replicas to continue functioning.

-.SS "Hot Spares"
-.sp
-.LP
-\fBZFS\fR allows devices to be associated with pools as "hot spares". These devices are not actively used in the pool, but when an active device fails, it is automatically replaced by a hot spare. To create a pool with hot spares, specify a "spare" \fBvdev\fR with any number of devices. For example,
-.sp
-.in +2
-.nf
-# zpool create pool mirror sda sdb spare sdc sdd
-.fi
-.in -2
-.sp
-
-.sp
-.LP
-Spares can be shared across multiple pools, and can be added with the "\fBzpool add\fR" command and removed with the "\fBzpool remove\fR" command. Once a spare replacement is initiated, a new "spare" \fBvdev\fR is created within the configuration that will remain there until the original device is replaced. At this point, the hot spare becomes available again.
-.sp
-.LP
-If a pool has a shared spare that is currently being used, the pool can not be exported since other pools may use this shared spare, which may lead to potential data corruption.
-.sp
-.LP
-An in-progress spare replacement can be cancelled by detaching the hot spare. If the original faulted device is detached, then the hot spare assumes its place in the configuration, and is removed from the spare list of all active pools.
-.sp
-.LP
-Spares cannot replace log devices.
-.SS "Intent Log"
-.sp
-.LP
-The \fBZFS\fR Intent Log (\fBZIL\fR) satisfies \fBPOSIX\fR requirements for synchronous transactions. For instance, databases often require their transactions to be on stable storage devices when returning from a system call. \fBNFS\fR and other applications can also use \fBfsync\fR() to ensure data stability. By default, the intent log is allocated from blocks within the main pool. However, it might be possible to get better performance using separate intent log devices such as \fBNVRAM\fR or a dedicated disk. For example:
-.sp
-.in +2
-.nf
-\fB# zpool create pool sda sdb log sdc\fR
-.fi
-.in -2
-.sp
-
-.sp
-.LP
-Multiple log devices can also be specified, and they can be mirrored. See the EXAMPLES section for an example of mirroring multiple log devices.
-.sp
-.LP
-Log devices can be added, replaced, attached, detached, and imported and exported as part of the larger pool. Mirrored log devices can be removed by specifying the top-level mirror for the log.
-.SS "Cache Devices"
-.sp
-.LP
-Devices can be added to a storage pool as "cache devices." These devices provide an additional layer of caching between main memory and disk. For read-heavy workloads, where the working set size is much larger than what can be cached in main memory, using cache devices allow much more of this working set to be served from low latency media. Using cache devices provides the greatest performance improvement for random read-workloads of mostly static content.
-.sp
-.LP
-To create a pool with cache devices, specify a "cache" \fBvdev\fR with any number of devices. For example:
-.sp
-.in +2
-.nf
-\fB# zpool create pool sda sdb cache sdc sdd\fR
-.fi
-.in -2
-.sp
-
-.sp
-.LP
-Cache devices cannot be mirrored or part of a \fBraidz\fR configuration. If a read error is encountered on a cache device, that read \fBI/O\fR is reissued to the original storage pool device, which might be part of a mirrored or \fBraidz\fR configuration.

-The content of the cache devices is considered volatile, as is the case with other system caches.

-The space usage properties report actual physical space available to the storage pool. The physical space can be different from the total amount of space that any contained datasets can actually use. The amount of space used in a \fBraidz\fR configuration depends on the characteristics of the data being written. In addition, \fBZFS\fR reserves some space for internal accounting that the \fBzfs\fR(8) command takes into account, but the \fBzpool\fR command does not. For non-full pools of a reasonable size, these effects should be invisible. For small pools, or pools that are close to being completely full, these discrepancies may become more noticeable.

-Pool sector size exponent, to the power of 2 (internally referred to as "ashift"). I/O operations will be aligned to the specified size boundaries. Additionally, the minimum (disk) write size will be set to the specified size, so this represents a space vs. performance trade-off. The typical case for setting this property is when performance is important and the underlying disks use 4KiB sectors but report 512B sectors to the OS (for compatibility reasons); in that case, set \fBashift=12\fR (which is 1<<12 = 4096).
-.LP
-For optimal performance, the pool sector size should be greater than or equal to the sector size of the underlying disks. Since the property cannot be changed after pool creation, if in a given pool, you \fIever\fR want to use drives that \fIreport\fR 4KiB sectors, you must set \fBashift=12\fR at pool creation time.

-The command verifies that each device specified is accessible and not currently in use by another subsystem.

-The command also checks that the replication strategy for the pool is consistent. An attempt to combine redundant and non-redundant storage in a single pool, or to mix disks and files, results in an error unless \fB-f\fR is specified.

-#
-# cstyle - check for some common stylistic errors.
-#
-# cstyle is a sort of "lint" for C coding style.
-# It attempts to check for the style used in the
-# kernel, sometimes known as "Bill Joy Normal Form".
-#
-# There's a lot this can't check for, like proper indentation
-# of code blocks. There's also a lot more this could check for.
-#
-# A note to the non perl literate:
-#
-# perl regular expressions are pretty much like egrep
-# regular expressions, with the following special symbols
-#
-# \s any space character
-# \S any non-space character
-# \w any "word" character [a-zA-Z0-9_]
-# \W any non-word character
-# \d a digit [0-9]
-# \D a non-digit
-# \b word boundary (between \w and \W)
-# \B non-word boundary

-# The current suite of fault tests should not be thought of an exhaustive
-# list of failure modes. Rather it is simply an starting point which trys
-# to cover the bulk the of the 'easy' and hopefully common, failure modes.
-#
-# Additional tests should be added but the current suite as new interesting
-# failures modes are observed. Additional failure modes I'd like to see
-# tests for include, but are not limited too:
-#
-# * Slow but successful IO.
-# * SCSI sense codes generated as zevents.
-# * 4k sectors
-# * noise
-# * medium error
-# * recovered error
-#
-# The current infrastructure using the 'mdadm' faulty device and the
-# 'scsi_debug' simulated scsi devices. The idea is to inject the error
-# below the zfs stack to validate all the error paths. More targeted
-# failure testing should be added using the 'zinject' command line util.
-#
-# Requires the following packages:
-# * mdadm
-# * lsscsi
-# * sg3-utils

-# Here's how it all works:
-#
-# The general idea is to build up
-# an intent log from a bunch of diverse user commands
-# without actually committing them to the file system.
-# Then copy the file system, replay the intent
-# log and compare the file system and the copy.
-#
-# To enable this automated testing of the intent log
-# requires some but minimal support from the file system.
-# In particular, a "freeze" command is required to flush
-# the in-flight transactions; to stop the actual
-# committing of transactions; and to ensure no deltas are
-# discarded. All deltas past a freeze point are kept for
-# replay and comparison later. Here is the flow:
-#
-# create an empty file system (FS)
-# freeze FS
-# run various user commands that create files, directories and ACLs
-# copy FS to temporary location (COPY)
-# unmount filesystem
-# <at this stage FS is empty again and unfrozen, and the
-# intent log contains a complete set of deltas to replay it>
-# remount FS <which replays the intent log>
-# compare FS against the COPY
-#

-# Verify that an assortment of known good reference pools can be imported
-# using different versions of the ZoL code.
-#
-# By default references pools for the major ZFS implementation will be
-# checked against the most recent ZoL tags and the master development branch.
-# Alternate tags or branches may be verified with the '-s <src-tag> option.
-# Passing the keyword "installed" will instruct the script to test whatever
-# version is installed.
-#
-# Preferentially a reference pool is used for all tests. However, if one
-# does not exist and the pool-tag matches one of the src-tags then a new
-# reference pool will be created using binaries from that source build.
-# This is particularly useful when you need to test your changes before
-# opening a pull request. The keyword 'all' can be used as short hand
-# refer to all available reference pools.
-#
-# New reference pools may be added by placing a bzip2 compressed tarball
-# of the pool in the scripts/zfs-images directory and then passing
-# the -p <pool-tag> option. To increase the test coverage reference pools
-# should be collected for all the major ZFS implementations. Having these
-# pools easily available is also helpful to the developers.
-#
-# Care should be taken to run these tests with a kernel supported by all
-# the listed tags. Otherwise build failure will cause false positives.
-#
-#
-# EXAMPLES:
-#
-# The following example will verify the zfs-0.6.2 tag, the master branch,
-# and the installed zfs version can correctly import the listed pools.
-# Note there is no reference pool available for master and installed but
-# because binaries are available one is automatically constructed. The
