ceph compact
+config
+------
+
+Configure the cluster. By default, Ceph daemons and clients retrieve their
+configuration options from monitor when they start, and are updated if any of
+the tracked options is changed at run time. It uses following additional
+subcommand.
+
+Subcommand ``dump`` to dump all options for the cluster
+
+Usage::
+
+ ceph config dump
+
+Subcommand ``ls`` to list all option names for the cluster
+
+Usage::
+
+ ceph config ls
+
+Subcommand ``help`` to describe the specified configuration option
+
+Usage::
+
+ ceph config help <option>
+
+Subcommand ``get`` to dump the option(s) for the specified entity.
+
+Usage::
+
+ ceph config get <who> {<option>}
+
+Subcommand ``show`` to display the running configuration of the specified
+entity. Please note, unlike ``get``, which only shows the options managed
+by monitor, ``show`` displays all the configurations being actively used.
+These options are pulled from several sources, for instance, the compiled-in
+default value, the monitor's configuration database, ``ceph.conf`` file on
+the host. The options can even be overridden at runtime. So, there is chance
+that the configuration options in the output of ``show`` could be different
+from those in the output of ``get``.
+
+Usage::
+
+ ceph config show {<who>}
+
+Subcommand ``show-with-defaults`` to display the running configuration along with the compiled-in defaults of the specified entity
+
+Usage::
+
+ ceph config show {<who>}
+
+Subcommand ``set`` to set an option for one or more specified entities
+
+Usage::
+
+ ceph config set <who> <option> <value> {--force}
+
+Subcommand ``rm`` to clear an option for one or more entities
+
+Usage::
+
+ ceph config rm <who> <option>
+
+Subcommand ``log`` to show recent history of config changes. If `count` option
+is omitted it defeaults to 10.
+
+Usage::
+
+ ceph config log {<count>}
+
+Subcommand ``reset`` to revert configuration to the specified historical version
+
+Usage::
+
+ ceph config reset <version>
+
+
+Subcommand ``assimilate-conf`` to assimilate options from stdin, and return a
+new, minimal conf file
+
+Usage::
+
+ ceph config assimilate-conf -i <input-config-path> > <output-config-path>
+ ceph config assimilate-conf < <input-config-path>
+
+Subcommand ``generate-minimal-conf`` to generate a minimal ``ceph.conf`` file,
+which can be used for bootstrapping a daemon or a client.
+
+Usage::
+
+ ceph config generate-minimal-conf > <minimal-config-path>
+
+
config-key
----------
-Manage configuration key. It uses some additional subcommands.
+Manage configuration key. Config-key is a general purpose key/value service
+offered by the monitors. This service is mainly used by Ceph tools and daemons
+for persisting various settings. Among which, ceph-mgr modules uses it for
+storing their options. It uses some additional subcommands.
Subcommand ``rm`` deletes configuration key.
fs
--
-Manage cephfs filesystems. It uses some additional subcommands.
+Manage cephfs file systems. It uses some additional subcommands.
-Subcommand ``ls`` to list filesystems
+Subcommand ``ls`` to list file systems
Usage::
ceph fs ls
-Subcommand ``new`` to make a new filesystem using named pools <metadata> and <data>
+Subcommand ``new`` to make a new file system using named pools <metadata> and <data>
Usage::
ceph fs reset <fs_name> {--yes-i-really-mean-it}
-Subcommand ``rm`` to disable the named filesystem
+Subcommand ``rm`` to disable the named file system
Usage::
Usage::
- ceph heap dump|start_profiler|stop_profiler|stats
+ ceph tell <name (type.id)> heap dump|start_profiler|stop_profiler|stats
Subcommand ``release`` to make TCMalloc to releases no-longer-used memory back to the kernel at once.
Usage::
- ceph heap release
+ ceph tell <name (type.id)> heap release
Subcommand ``(get|set)_release_rate`` get or set the TCMalloc memory release rate. TCMalloc releases
no-longer-used memory back to the kernel gradually. the rate controls how quickly this happens.
Usage::
- ceph heap get_release_rate|set_release_rate {<val>}
+ ceph tell <name (type.id)> heap get_release_rate|set_release_rate {<val>}
injectargs
----------
ceph mon stat
-mon_status
-----------
-
-Reports status of monitors.
-
-Usage::
-
- ceph mon_status
-

Usage::
- ceph osd pool create <poolname> <int[0-]> {<int[0-]>} {replicated|erasure}
- {<erasure_code_profile>} {<rule>} {<int>}
+ ceph osd pool create <poolname> {<int[0-]>} {<int[0-]>} {replicated|erasure}
+ {<erasure_code_profile>} {<rule>} {<int>} {--autoscale-mode=<on,off,warn>}
Subcommand ``delete`` deletes pool.
ceph osd pool application enable <pool-name> <app> {--yes-i-really-mean-it}
-Subcommand ``get`` displays the value for the given key that is assosciated
+Subcommand ``get`` displays the value for the given key that is associated
with the given application of the given pool. Not passing the optional
arguments would display all key-value pairs for all applications for all
pools.
ceph osd scrub <who>
-Subcommand ``set`` sets <key>.
+Subcommand ``set`` sets cluster-wide <flag> by updating OSD map.
+The ``full`` flag is not honored anymore since the Mimic release, and
+``ceph osd set full`` is not supported in the Octopus release.
Usage::
- ceph osd set full|pause|noup|nodown|noout|noin|nobackfill|
+ ceph osd set pause|noup|nodown|noout|noin|nobackfill|
norebalance|norecover|noscrub|nodeep-scrub|notieragent
Subcommand ``setcrushmap`` sets crush map from input file.
Usage::
- ceph osd tier cache-mode <poolname> none|writeback|forward|readonly|
- readforward|readproxy
+ ceph osd tier cache-mode <poolname> writeback|readproxy|readonly|none
Subcommand ``remove`` removes the tier <tierpool> (the second one) from base pool
<pool> (the first one).
ceph osd unpause
-Subcommand ``unset`` unsets <key>.
+Subcommand ``unset`` unsets cluster-wide <flag> by updating OSD map.

-If you want a specific MON to enter or exit quorum, use this syntax::
-
ceph tell mon.<id> quorum enter|exit
quorum_status
ceph report {<tags> [<tags>...]}
