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.
