Usage:: ceph tell [...] version ------- Show mon daemon version Usage:: ceph version 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 Watch error events. .. option:: --version, -v Display version. .. 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.
