Release Notes
===============
+v12.1.0 Luminous (RC)
+=====================
+
+This is the first release candidate for Luminous, the next long term
+stable release.
+
+Ceph Luminous (v12.2.0) will be the foundation for the next long-term
+stable release series. There have been major changes since Kraken
+(v11.2.z) and Jewel (v10.2.z), and the upgrade process is non-trivial.
+Please read these release notes carefully.
+
+Major Changes from Kraken
+-------------------------
+
+- *General*:
+
+ * Ceph now has a simple, built-in web-based dashboard for monitoring
+ cluster status. FIXME DOCS.
+
+- *RADOS*:
+
+ * *BlueStore*:
+
+ - The new *BlueStore* backend for *ceph-osd* is now stable and the new
+ default for newly created OSDs. BlueStore manages data stored by each OSD
+ by directly managing the physical HDDs or SSDs without the use of an
+ intervening file system like XFS. This provides greater performance
+ and features. FIXME DOCS
+ - BlueStore supports *full data and metadata checksums* of all
+ data stored by Ceph.
+ - BlueStore supports inline compression using zlib, snappy, or LZ4. (Ceph
+ also supports zstd for RGW compression but zstd is not recommended for
+ BlueStore for performance reasons.) FIXME DOCS
+
+ * *Erasure coded* pools now have full support for *overwrites*,
+ allowing them to be used with RBD and CephFS. `Read more about EC overwrites`_.
+
+ * *ceph-mgr*:
+
+ - There is a new daemon, *ceph-mgr*, which is a required part of any
+ Ceph deployment. Although IO can continue when *ceph-mgr* is
+ down, metrics will not refresh and some metrics-related calls
+ (e.g., ``ceph df``) may block. We recommend deploying several instances of
+ *ceph-mgr* for reliability. See the notes on `Upgrading`_ below.
+ - The *ceph-mgr* daemon includes a REST-based management API. The
+ API is still experimental and somewhat limited but will form the basis
+ for API-based management of Ceph going forward. FIXME DOCS
+
+ * The overall *scalability* of the cluster has improved. We have
+ successfully tested clusters with up to 10,000 OSDs.
+ * Each OSD can now have a *device class* associated with it (e.g., `hdd` or
+ `ssd`), allowing CRUSH rules to trivially map data to a subset of devices
+ in the system. Manually writing CRUSH rules or manual editing of the CRUSH
+ is normally not required. FIXME DOCS
+ * You can now *optimize CRUSH weights* can now be optimized to
+ maintain a *near-perfect distribution of data* across OSDs. FIXME DOCS
+ * There is also a new `upmap` exception mechanism that allows
+ individual PGs to be moved around to achieve a *perfect
+ distribution* (this requires luminous clients). FIXME DOCS
+ * Each OSD now adjusts its default configuration based on whether the
+ backing device is an HDD or SSD. Manual tuning generally not required.
+ * The prototype *mclock QoS queueing algorithm* is now available. FIXME DOCS
+ * There is now a *backoff* mechanism that prevents OSDs from being
+ overloaded by requests to objects or PGs that are not currently able to
+ process IO.
+ * There is a *simplified OSD replacement process* that is more robust. FIXME DOCS
+ * You can query the supported features and (apparent) releases of
+ all connected daemons and clients with ``ceph features``. FIXME DOCS
+ * You can configure the oldest Ceph client version you wish to allow to
+ connect to the cluster via ``ceph osd set-require-min-compat-client`` and
+ Ceph will prevent you from enabling features that will break compatibility
+ with those clients. FIXME DOCS
+ * Several `sleep` settings, include ``osd_recovery_sleep``,
+ ``osd_snap_trim_sleep``, and ``osd_scrub_sleep`` have been
+ reimplemented to work efficiently. (These are used in some cases
+ to work around issues throttling background work.)
+
+- *RGW*:
+
+ * RGW *metadata search* backed by ElasticSearch now supports end
+ user requests service via RGW itself, and also supports custom
+ metadata fields. A query language a set of RESTful APIs were
+ created for users to be able to search objects by their
+ metadata. New APIs that allow control of custom metadata fields
+ were also added.
+ * RGW now supports *dynamic bucket index sharding*. As the number
+ of objects in a bucket grows, RGW will automatically reshard the
+ bucket index in response. No user intervention or bucket size
+ capacity planning is required.
+ * RGW introduces *server side encryption* of uploaded objects with
+ three options for the management of encryption keys: automatic
+ encryption (only recommended for test setups), customer provided
+ keys similar to Amazon SSE-C specification, and through the use of
+ an external key management service (Openstack Barbican) similar
+ to Amazon SSE-KMS specification.
+ * RGW now has preliminary AWS-like bucket policy API support. For
+ now, policy is a means to express a range of new authorization
+ concepts. In the future it will be the foundation for additional
+ auth capabilities such as STS and group policy.
+ * RGW has consolidated the several metadata index pools via the use of rados
+ namespaces.
+
+- *RBD*:
+
+ * RBD now has full, stable support for *erasure coded pools* via the new
+ ``--data-pool`` option to ``rbd create``.
+ * RBD mirroring's rbd-mirror daemon is now highly available. We
+ recommend deploying several instances of rbd-mirror for
+ reliability.
+ * The default 'rbd' pool is no longer created automatically during
+ cluster creation. Additionally, the name of the default pool used
+ by the rbd CLI when no pool is specified can be overridden via a
+ new ``rbd default pool = <pool name>`` configuration option.
+ * Initial support for deferred image deletion via new ``rbd
+ trash`` CLI commands. Images, even ones actively in-use by
+ clones, can be moved to the trash and deleted at a later time.
+ * New pool-level ``rbd mirror pool promote`` and ``rbd mirror pool
+ demote`` commands to batch promote/demote all mirrored images
+ within a pool.
+ * Mirroring now optionally supports a configurable replication delay
+ via the ``rbd mirroring replay delay = <seconds>`` configuration
+ option.
+ * Improved discard handling when the object map feature is enabled.
+ * rbd CLI ``import`` and ``copy`` commands now detect sparse and
+ preserve sparse regions.
+ * Images and Snapshots will now include a creation timestamp
+
+- *CephFS*:
+
+ * *Multiple active MDS daemons* is now considered stable. The number
+ of active MDS servers may be adjusted up or down on an active CephFS file
+ system.
+ * CephFS *directory fragmentation* is now stable and enabled by
+ default on new filesystems. To enable it on existing filesystems
+ use "ceph fs set <fs_name> allow_dirfrags". Large or very busy
+ directories are sharded and (potentially) distributed across
+ multiple MDS daemons automatically.
+ * Directory subtrees can be explicitly pinned to specific MDS daemons in
+ cases where the automatic load balancing is not desired or effective.
+
+- *Miscellaneous*:
+
+ * Release packages are now being built for *Debian Stretch*. The
+ distributions we build for now includes:
+
+ - CentOS 7 (x86_64 and aarch64)
+ - Debian 8 Jessie (x86_64)
+ - Debian 9 Stretch (x86_64)
+ - Ubuntu 16.04 Xenial (x86_64 and aarch64)
+ - Ubuntu 14.04 Trusty (x86_64)
+
+ Note that QA is limited to CentOS and Ubuntu (xenial and trusty).
+
+ * *CLI changes*:
+
+ - The ``ceph -s`` or ``ceph status`` command has a fresh look.
+ - ``ceph {osd,mds,mon} versions`` summarizes versions of running daemons.
+ - ``ceph {osd,mds,mon} count-metadata <property>`` similarly
+ tabulates any other daemon metadata visible via the ``ceph
+ {osd,mds,mon} metadata`` commands.
+ - ``ceph features`` summarizes features and releases of connected
+ clients and daemons.
+ - ``ceph osd require-osd-release <release>`` replaces the old
+ ``require_RELEASE_osds`` flags.
+ - ``ceph osd pg-upmap``, ``ceph osd rm-pg-upmap``, ``ceph osd
+ pg-upmap-items``, ``ceph osd rm-pg-upmap-items`` can explicitly
+ manage `upmap` items (FIXME DOCS).
+ - ``ceph osd getcrushmap`` returns a crush map version number on
+ stderr, and ``ceph osd setcrushmap [version]`` will only inject
+ an updated crush map if the version matches. This allows crush
+ maps to be updated offline and then reinjected into the cluster
+ without fear of clobbering racing changes (e.g., by newly added
+ osds or changes by other administrators).
+ - ``ceph osd create`` has been replaced by ``ceph osd new``. This
+ should be hidden from most users by user-facing tools like
+ `ceph-disk`.
+ - ``ceph osd destroy`` will mark an OSD destroyed and remove its
+ cephx and lockbox keys. However, the OSD id and CRUSH map entry
+ will remain in place, allowing the id to be reused by a
+ replacement device with minimal data rebalancing.
+ - ``ceph osd purge`` will remove all traces of an OSD from the
+ cluster, including its cephx encryption keys, dm-crypt lockbox
+ keys, OSD id, and crush map entry.
+ - ``ceph osd ls-tree <name>`` will output a list of OSD ids under
+ the given CRUSH name (like a host or rack name). This is useful
+ for applying changes to entire subtrees. For example, ``ceph
+ osd down `ceph osd ls-tree rack1```.
+ - ``ceph osd {add,rm}-{noout,noin,nodown,noup}`` allow the
+ `noout`, `nodown`, `noin`, and `noup` flags to be applied to
+ specific OSDs.
+ - ``ceph log last [n]`` will output the last *n* lines of the cluster
+ log.
+ - ``ceph mgr dump`` will dump the MgrMap, including the currently active
+ ceph-mgr daemon and any standbys.
+ - ``ceph mgr module ls`` will list active ceph-mgr modules.
+ - ``ceph mgr module {enable,disable} <name>`` will enable or
+ disable the named mgr module. The module must be present in the
+ configured `mgr_module_path` on the host(s) where `ceph-mgr` is
+ running.
+ - ``ceph osd crush swap-bucket <src> <dest>`` will swap the
+ contents of two CRUSH buckets in the hierarchy while preserving
+ the buckets' ids. This allows an entire subtree of devices to
+ be replaced (e.g., to replace an entire host of FileStore OSDs
+ with newly-imaged BlueStore OSDs) without disrupting the
+ distribution of data across neighboring devices.
+ - ``ceph osd set-require-min-compat-client <release>`` configures
+ the oldest client release the cluster is required to support.
+ Other changes, like CRUSH tunables, will fail with an error if
+ they would violate this setting. Changing this setting also
+ fails if clients older than the specified release are currently
+ connected to the cluster.
+ - ``ceph config-key dump`` dumps config-key entries and their
+ contents. (The existing ``ceph config-key list`` only dumps the key
+ names, not the values.)
+ - ``ceph osd set-{full,nearfull,backfillfull}-ratio`` sets the
+ cluster-wide ratio for various full thresholds (when the cluster
+ refuses IO, when the cluster warns about being close to full,
+ when an OSD will defer rebalancing a PG to itself,
+ respectively).
+ - ``ceph osd reweightn`` will specify the `reweight` values for
+ multiple OSDs in a single command. This is equivalent to a series of
+ ``ceph osd reweight`` commands.
+ - ``ceph osd crush class {create,rm,ls,rename}`` manage the new
+ CRUSH *device class* feature. ``ceph crush set-device-class
+ <class> <osd> [<osd>...]`` will set the class for particular devices.
+ - ``ceph osd crush rule create-replicated`` replaces the old
+ ``ceph osd crush rule create-simple`` command to create a CRUSH
+ rule for a replicated pool. Notably it takes a `class` argument
+ for the *device class* the rule should target (e.g., `ssd` or
+ `hdd`).
+ - ``ceph mon feature ls`` will list monitor features recorded in the
+ MonMap. ``ceph mon feature set`` will set an optional feature (none of
+ these exist yet).
+ - ``ceph tell <daemon> help`` will now return a usage summary.

+
+Major Changes from Jewel
+------------------------
+
+- *RADOS*:
+
+ * We now default to the AsyncMessenger (``ms type = async``) instead
+ of the legacy SimpleMessenger. The most noticeable difference is
+ that we now use a fixed sized thread pool for network connections
+ (instead of two threads per socket with SimpleMessenger).
+ * Some OSD failures are now detected almost immediately, whereas
+ previously the heartbeat timeout (which defaults to 20 seconds)
+ had to expire. This prevents IO from blocking for an extended
+ period for failures where the host remains up but the ceph-osd
+ process is no longer running.
+ * The size of encoded OSDMaps has been reduced.
+ * The OSDs now quiesce scrubbing when recovery or rebalancing is in progress.
+
+- *RGW*:
+
+ * RGW now supports the S3 multipart object copy-part API.
+ * It is possible now to reshard an existing bucket offline. Offline
+ bucket resharding currently requires that all IO (especially
+ writes) to the specific bucket is quiesced. (For automatic online
+ resharding, see the new feature in Luminous above.)
+ * RGW now supports data compression for objects.
+ * Civetweb version has been upgraded to 1.8
+ * The Swift static website API is now supported (S3 support has been added
+ previously).
+ * S3 bucket lifecycle API has been added. Note that currently it only supports
+ object expiration.
+ * Support for custom search filters has been added to the LDAP auth
+ implementation.
+ * Support for NFS version 3 has been added to the RGW NFS gateway.
+ * A Python binding has been created for librgw.
+
+- *RBD*:
+
+ * The rbd-mirror daemon now supports replicating dynamic image
+ feature updates and image metadata key/value pairs from the
+ primary image to the non-primary image.
+ * The number of image snapshots can be optionally restricted to a
+ configurable maximum.
+ * The rbd Python API now supports asynchronous IO operations.
+
+- *CephFS*:
+
+ * libcephfs function definitions have been changed to enable proper
+ uid/gid control. The library version has been increased to reflect the
+ interface change.
+ * Standby replay MDS daemons now consume less memory on workloads
+ doing deletions.
+ * Scrub now repairs backtrace, and populates `damage ls` with
+ discovered errors.
+ * A new `pg_files` subcommand to `cephfs-data-scan` can identify
+ files affected by a damaged or lost RADOS PG.
+ * The false-positive "failing to respond to cache pressure" warnings have
+ been fixed.
+
+
+Upgrade from Jewel or Kraken
+----------------------------
+.. _Upgrading:
+
+#. Ensure that the ``sortbitwise`` flag is enabled::
+
+ # ceph osd set sortbitwise
+
+#. Make sure your cluster is stable and healthy (no down or
+ recoverying OSDs). (Optional, but recommended.)
+
+#. Do not create any new erasure-code pools while upgrading the monitors.
+
+#. Set the ``noout`` flag for the duration of the upgrade. (Optional
+ but recommended.)::
+
+ # ceph osd set noout
+
+#. Upgrade monitors by installing the new packages and restarting the
+ monitor daemons. Note that, unlike prior releases, the ceph-mon
+ daemons *must* be upgraded first.::
+
+ # systemctl restart ceph-mon.target
+
+ Verify the monitor upgrade is complete once all monitors are up by
+ looking for the ``luminous`` feature string in the mon map. For
+ example::
+
+ # ceph mon feature ls
+
+ should include `luminous` under persistent features::
+
+ on current monmap (epoch NNN)
+ persistent: [kraken,luminous]
+ required: [kraken,luminous]
+
+#. Add or restart ``ceph-mgr`` daemons. If you are upgrading from
+ kraken, upgrade packages and restart ceph-mgr daemons with::
+
+ # systemctl restart ceph-mgr.target
+
+ If you are upgrading from kraken, you may already have ceph-mgr
+ daemons deployed. If not, or if you are upgrading from jewel, you
+ can deploy new daemons with tools like ceph-deploy or ceph-ansible.
+ For example,::
+
+ # ceph-deploy mgr create HOST
+
+ Verify the ceph-mgr daemons are running by checking ``ceph -s``::
+
+ # ceph -s
+
+ ...
+ services:
+ mon: 3 daemons, quorum foo,bar,baz
+ mgr: foo(active), standbys: bar, baz
+ ...
+
+#. Upgrade all OSDs by installing the new packages and restarting the
+ ceph-osd daemons on all hosts.::
+
+ # systemctl restart ceph-osd.target
+
+ You can monitor the progress of the OSD upgrades with the new
+ ``ceph osd versions`` command.::
+
+ # ceph osd versions
+ {
+ "ceph version 12.2.0 (...) luminous (stable)": 12,
+ "ceph version 10.2.6 (...)": 3,
+ }
+
+#. Upgrade all CephFS daemons by upgrading packages and restarting
+ daemons on all hosts.::
+
+ # systemctl restart ceph-mds.target
+
+#. Upgrade all radosgw daemons by upgrading packages and restarting
+ daemons on all hosts.::
+
+ # systemctl restart radosgw.target
+
+#. Complete the upgrade by disallowing pre-luminous OSDs::
+
+ # ceph osd require-osd-release luminous
+
+ If you set ``noout`` at the beginning, be sure to clear it with::
+
+ # ceph osd unset noout
+
+#. Verify the cluster is healthy with ``ceph health``.
+
+
+Upgrading from pre-Jewel releases (like Hammer)
+-----------------------------------------------
+
+You *must* first upgrade to Jewel (10.2.z) before attempting an
+upgrade to Luminous.
+
+
+Upgrade compatibility notes, Kraken to Luminous
+-----------------------------------------------
+
+* We no longer test the FileStore ceph-osd backend in combination with
+ ``btrfs``. We recommend against using btrfs. If you are using
+ btrfs-based OSDs and want to upgrade to luminous you will need to
+ add the follwing to your ceph.conf::
+
+ enable experimental unrecoverable data corrupting features = btrfs
+
+ The code is mature and unlikely to change, but we are only
+ continuing to test the Jewel stable branch against btrfs. We
+ recommend moving these OSDs to FileStore with XFS or BlueStore.
+* The ``ruleset-*`` properties for the erasure code profiles have been
+ renamed to ``crush-*`` to (1) move away from the obsolete 'ruleset'
+ term and to be more clear about their purpose. There is also a new
+ optional ``crush-device-class`` property to specify a CRUSH device
+ class to use for the erasure coded pool. Existing erasure code
+ profiles will be converted automatically when upgrade completes
+ (when the ``ceph osd require-osd-release luminous`` command is run)
+ but any provisioning tools that create erasure coded pools may need
+ to be updated.
+* When assigning a network to the public network and not to
+ the cluster network the network specification of the public
+ network will be used for the cluster network as well.
+ In older versions this would lead to cluster services
+ being bound to 0.0.0.0:<port>, thus making the
+ cluster service even more publicly available than the
+ public services. When only specifying a cluster network it
+ will still result in the public services binding to 0.0.0.0.
+
+* In previous versions, if a client sent an op to the wrong OSD, the OSD
+ would reply with ENXIO. The rationale here is that the client or OSD is
+ clearly buggy and we want to surface the error as clearly as possible.
+ We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
+ is enabled (it's off by default). This means that a VM using librbd that
+ previously would have gotten an EIO and gone read-only will now see a
+ blocked/hung IO instead.
+
+* The "journaler allow split entries" config setting has been removed.
+
+- *librados*:
+
+ * Some variants of the omap_get_keys and omap_get_vals librados
+ functions have been deprecated in favor of omap_get_vals2 and
+ omap_get_keys2. The new methods include an output argument
+ indicating whether there are additional keys left to fetch.
+ Previously this had to be inferred from the requested key count vs
+ the number of keys returned, but this breaks with new OSD-side
+ limits on the number of keys or bytes that can be returned by a
+ single omap request. These limits were introduced by kraken but
+ are effectively disabled by default (by setting a very large limit
+ of 1 GB) because users of the newly deprecated interface cannot
+ tell whether they should fetch more keys or not. In the case of
+ the standalone calls in the C++ interface
+ (IoCtx::get_omap_{keys,vals}), librados has been updated to loop on
+ the client side to provide a correct result via multiple calls to
+ the OSD. In the case of the methods used for building
+ multi-operation transactions, however, client-side looping is not
+ practical, and the methods have been deprecated. Note that use of
+ either the IoCtx methods on older librados versions or the
+ deprecated methods on any version of librados will lead to
+ incomplete results if/when the new OSD limits are enabled.
+
+ * The original librados rados_objects_list_open (C) and objects_begin
+ (C++) object listing API, deprecated in Hammer, has finally been
+ removed. Users of this interface must update their software to use
+ either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
+ the new rados_object_list_begin (C) and object_list_begin (C++) API
+ before updating the client-side librados library to Luminous.
+ Object enumeration (via any API) with the latest librados version
+ and pre-Hammer OSDs is no longer supported. Note that no in-tree
+ Ceph services rely on object enumeration via the deprecated APIs, so
+ only external librados users might be affected.
+
+ The newest (and recommended) rados_object_list_begin (C) and
+ object_list_begin (C++) API is only usable on clusters with the
+ SORTBITWISE flag enabled (Jewel and later). (Note that this flag is
+ required to be set before upgrading beyond Jewel.)
+
+- *CephFS*:
+
+ * When configuring ceph-fuse mounts in /etc/fstab, a new syntax is
+ available that uses "ceph.<arg>=<val>" in the options column, instead
+ of putting configuration in the device column. The old style syntax
+ still works. See the documentation page "Mount CephFS in your
+ file systems table" for details.
+
+ * CephFS clients without the 'p' flag in their authentication capability
+ string will no longer be able to set quotas or any layout fields. This
+ flag previously only restricted modification of the pool and namespace
+ fields in layouts.
+ * CephFS will generate a health warning if you have fewer standby daemons
+ than it thinks you wanted. By default this will be 1 if you ever had
+ a standby, and 0 if you did not. You can customize this using
+ ``ceph fs set <fs> standby_count_wanted <number>``. Setting it
+ to zero will effectively disable the health check.
+ * The "ceph mds tell ..." command has been removed. It is superceded
+ by "ceph tell mds.<id> ..."
+

v12.0.2 Luminous (dev)
======================
This is the third development checkpoint release of Luminous, the next long term
Major changes from v12.0.1
--------------------------
-* The original librados rados_objects_list_open (C) and objects_begin
- (C++) object listing API, deprecated in Hammer, has finally been
- removed. Users of this interface must update their software to use
- either the rados_nobjects_list_open (C) and nobjects_begin (C++) API or
- the new rados_object_list_begin (C) and object_list_begin (C++) API
- before updating the client-side librados library to Luminous.
-
- Object enumeration (via any API) with the latest librados version
- and pre-Hammer OSDs is no longer supported. Note that no in-tree
- Ceph services rely on object enumeration via the deprecated APIs, so
- only external librados users might be affected.
-
- The newest (and recommended) rados_object_list_begin (C) and
- object_list_begin (C++) API is only usable on clusters with the
- SORTBITWISE flag enabled (Jewel and later). (Note that this flag is
- required to be set before upgrading beyond Jewel.)
-* CephFS clients without the 'p' flag in their authentication capability
- string will no longer be able to set quotas or any layout fields. This
- flag previously only restricted modification of the pool and namespace
- fields in layouts.
-* CephFS directory fragmentation (large directory support) is enabled
- by default on new filesystems. To enable it on existing filesystems
- use "ceph fs set <fs_name> allow_dirfrags".
-* CephFS will generate a health warning if you have fewer standby daemons
- than it thinks you wanted. By default this will be 1 if you ever had
- a standby, and 0 if you did not. You can customize this using
- ``ceph fs set <fs> standby_count_wanted <number>``. Setting it
- to zero will effectively disable the health check.
-* The "ceph mds tell ..." command has been removed. It is superceded
- by "ceph tell mds.<id> ..."
-* RGW introduces server side encryption of uploaded objects with 3 options for
- the management of encryption keys, automatic encryption (only recommended for
- test setups), customer provided keys similar to Amazon SSE KMS specification &
- using a key management service (openstack barbician)

long term release. We're off to a good start to release Luminous in the spring
of '17.
-Major changes from Kraken
--------------------------
- * When assigning a network to the public network and not to
- the cluster network the network specification of the public
- network will be used for the cluster network as well.
- In older versions this would lead to cluster services
- being bound to 0.0.0.0:<port>, thus making the
- cluster service even more publicly available than the
- public services. When only specifying a cluster network it
- will still result in the public services binding to 0.0.0.0.
-
-* Some variants of the omap_get_keys and omap_get_vals librados
- functions have been deprecated in favor of omap_get_vals2 and
- omap_get_keys2. The new methods include an output argument
- indicating whether there are additional keys left to fetch.
- Previously this had to be inferred from the requested key count vs
- the number of keys returned, but this breaks with new OSD-side
- limits on the number of keys or bytes that can be returned by a
- single omap request. These limits were introduced by kraken but
- are effectively disabled by default (by setting a very large limit
- of 1 GB) because users of the newly deprecated interface cannot
- tell whether they should fetch more keys or not. In the case of
- the standalone calls in the C++ interface
- (IoCtx::get_omap_{keys,vals}), librados has been updated to loop on
- the client side to provide a correct result via multiple calls to
- the OSD. In the case of the methods used for building
- multi-operation transactions, however, client-side looping is not
- practical, and the methods have been deprecated. Note that use of
- either the IoCtx methods on older librados versions or the
- deprecated methods on any version of librados will lead to
- incomplete results if/when the new OSD limits are enabled.
-
-* In previous versions, if a client sent an op to the wrong OSD, the OSD
- would reply with ENXIO. The rationale here is that the client or OSD is
- clearly buggy and we want to surface the error as clearly as possible.
- We now only send the ENXIO reply if the osd_enxio_on_misdirected_op option
- is enabled (it's off by default). This means that a VM using librbd that
- previously would have gotten an EIO and gone read-only will now see a
- blocked/hung IO instead.
-
-* When configuring ceph-fuse mounts in /etc/fstab, a new syntax is
- available that uses "ceph.<arg>=<val>" in the options column, instead
- of putting configuration in the device column. The old style syntax
- still works. See the documentation page "Mount CephFS in your
- file systems table" for details.
Notable Changes
to Kraken 11.2.z (or, eventually, Luminous 12.2.z).
* The ``sortbitwise`` flag must be set on the Jewel cluster before upgrading
- to Kraken. The latest Jewel (10.2.4+) releases issue a health warning if
+ to Kraken. The latest Jewel (10.2.8+) releases issue a health warning if
the flag is not set, so this is probably already set. If it is not, Kraken
OSDs will refuse to start and will print and error message in their log.

+v10.2.9 Jewel
+=============
+
+This point release fixes a regression introduced in v10.2.8.
+
+We recommend that all Jewel users upgrade.
+

+
+
+Notable Changes
+---------------
+
+* cephfs: Damaged MDS with 10.2.8 (`issue#20599 <http://tracker.ceph.com/issues/20599>`_, `pr#16282 <https://github.com/ceph/ceph/pull/16282>`_, Nathan Cutler)
+
+
+
+v10.2.8 Jewel
+=============
+
+This point release brought a number of important bugfixes in all major
+components of Ceph. However, it also introduced a regression that could cause
+MDS damage, and a new release, v10.2.9, was published to address this.
+Therefore, Jewel users should *not* upgrade to this version - instead, we
+recommend upgrading directly to v10.2.9.
+
+For more detailed information, see :download:`the complete changelog <changelog/v10.2.8.txt>`.
+
+OSD Removal Caveat
+------------------
+
+There was a bug introduced in Jewel (#19119) that broke the mapping behavior
+when an "out" OSD that still existed in the CRUSH map was removed with 'osd rm'.
+This could result in 'misdirected op' and other errors. The bug is now fixed,
+but the fix itself introduces the same risk because the behavior may vary between
+clients and OSDs. To avoid problems, please ensure that all OSDs are removed
+from the CRUSH map before deleting them. That is, be sure to do::
+
+ ceph osd crush rm osd.123
+
+before::
+
+ ceph osd rm osd.123
+
+Snap Trimmer Improvements
+-------------------------
+
+This release greatly improves control and throttling of the snap trimmer. It
+introduces the "osd max trimming pgs" option (defaulting to 2), which limits
+how many PGs on an OSD can be trimming snapshots at a time. And it restores
+the safe use of the "osd snap trim sleep" option, wihch defaults to 0 but
+otherwise adds the given number of seconds in delay between every dispatch
+of trim operations to the underlying system.
