===========
|
|
|
|
:program:`ceph` is a control utility which is used for manual deployment and maintenance

Options
|
|
=======
|
|
|
|
.. option:: -i infile
|
|
|
|
will specify an input file to be passed along as a payload with the
|
|
command to the monitor cluster. This is only used for specific
|
|
monitor commands.
|
|
|
|
.. option:: -o outfile
|
|
|
|
will write any payload returned by the monitor cluster with its
|
|
reply to outfile. Only specific monitor commands (e.g. osd getmap)
|
|
return a payload.
|
|
|
|
.. option:: -c ceph.conf, --conf=ceph.conf
|
|
|
|
Use ceph.conf configuration file instead of the default
|
|
``/etc/ceph/ceph.conf`` to determine monitor addresses during startup.
|
|
|
|
.. option:: --id CLIENT_ID, --user CLIENT_ID
|
|
|
|
Client id for authentication.
|
|
|
|
.. option:: --name CLIENT_NAME, -n CLIENT_NAME
|
|
|
|
Client name for authentication.
|
|
|
|
.. option:: --cluster CLUSTER
|
|
|
|
Name of the Ceph cluster.
|
|
|
|
.. option:: --admin-daemon ADMIN_SOCKET, daemon DAEMON_NAME
|
|
|
|
Submit admin-socket commands via admin sockets in /var/run/ceph.
|
|
|
|
.. option:: --admin-socket ADMIN_SOCKET_NOPE
|
|
|

You probably mean --admin-daemon
|

|
|
.. option:: -s, --status
|
|
|
|
Show cluster status.
|
|
|
|
.. option:: -w, --watch
|
|
|
|
Watch live cluster changes.
|
|
|
|
.. option:: --watch-debug
|
|
|
|
Watch debug events.
|
|
|
|
.. option:: --watch-info
|
|
|
|
Watch info events.
|
|
|
|
.. option:: --watch-sec
|
|
|
|
Watch security events.
|
|
|
|
.. option:: --watch-warn
|
|
|
|
Watch warning events.
|
|
|
|
.. option:: --watch-error
|
|
|

|
|
.. option:: --version, -v
|
|
|
|

|
|
|
|
.. option:: --verbose
|
|
|
|
Make verbose.
|
|
|
|
.. option:: --concise
|
|
|
|
Make less verbose.
|
|
|
|
.. option:: -f {json,json-pretty,xml,xml-pretty,plain}, --format
|
|
|
|
Format of output.
|
|
|
|
.. option:: --connect-timeout CLUSTER_TIMEOUT
|
|
|
|
Set a timeout for connecting to the cluster.
|
|
|
|
.. option:: --no-increasing
|
|
|
|
``--no-increasing`` is off by default. So increasing the osd weight is allowed
|
|
using the ``reweight-by-utilization`` or ``test-reweight-by-utilization`` commands.
|
|
If this option is used with these commands, it will help not to increase osd weight
|
|
even the osd is under utilized.
