CephFS Administrative commands
|
|
==============================
|
|
|
|
Filesystems
|
|
-----------
|
|
|
|
These commands operate on the CephFS filesystems in your Ceph cluster.
|
|
Note that by default only one filesystem is permitted: to enable
|
|
creation of multiple filesystems use ``ceph fs flag set enable_multiple true``.
|
|
|
|
::
|
|
|
|
fs new <filesystem name> <metadata pool name> <data pool name>
|
|
|
|
::
|
|
|
|
fs ls
|
|
|
|
::
|
|
|
|
fs rm <filesystem name> [--yes-i-really-mean-it]
|
|
|
|
::
|
|
|
|
fs reset <filesystem name>
|
|
|
|
::
|
|
|
|
fs get <filesystem name>
|
|
|
|
::
|
|
|
|
fs set <filesystem name> <var> <val>
|
|
|
|
::
|
|
|
|
fs add_data_pool <filesystem name> <pool name/id>
|
|
|
|
::
|
|
|
|
fs rm_data_pool <filesystem name> <pool name/id>
|
|
|
|
|
|
Daemons
|
|
-------
|
|
|
|
These commands act on specific mds daemons or ranks. For convenience,
|
|
they accept arguments that
|
|
|
|
::
|
|
|
|
mds fail <gid/name/role
|
|
|
|
::
|
|
|
|
mds deactivate <role>
|
|
|
|
::
|
|
|
|
tell mds.<daemon name>
|
|
|
|
::
|
|
|
|
mds metadata <gid/name/role>
|
|
|
|
::
|
|
|
|
mds repaired <role>
|
|
|
|
|
|
|
|
Global settings
|
|
---------------
|
|
|
|
::
|
|
|
|
fs dump
|
|
|
|
::
|
|
|
|
fs flag set <flag name> <flag val> [<confirmation string>]
|
|
|
|
flag name must be one of ['enable_multiple']
|
|
|
|
some flags require you to confirm your intentions with "--yes-i-really-mean-it"
|
|
or a similar string they will prompt you with. Consider these actions carefully
|
|
before proceeding; they are placed on especially dangerous activities.
|
|
|
|
Advanced
|
|
--------
|
|
|
|
These commands are not required in normal operation, and exist
|
|
for use in exceptional circumstances. Incorrect use of these
|
|
commands may cause serious problems, such as an inaccessible
|
|
filesystem.
