One or more instances of ceph-mds collectively manage the file +system namespace, coordinating access to the shared OSD cluster. + +Each ceph-mds daemon instance should have a unique name. The name is used +to identify daemon instances in the ceph.conf. + +Once the daemon has started, the monitor cluster will normally assign +it a logical rank, or put it in a standby pool to take over for +another daemon that crashes. Some of the specified options can cause +other behaviors. + +If you specify hot-standby, you must either specify the rank on the command +line, or specify one of the mds_standby_for_[rank|name] parameters in the +config. The command line specification overrides the config, and specifying +the rank overrides specifying the name. + + +Options +======= + +.. option:: -f, --foreground + + Foreground: do not daemonize after startup (run in foreground). Do + not generate a pid file. Useful when run via :doc:`ceph-run + `\(8). + +.. option:: -d + + Debug mode: like ``-f``, but also send all log output to stderr. + +.. option:: --setuser userorgid + + Set uid after starting. If a username is specified, the user + record is looked up to get a uid and a gid, and the gid is also set + as well, unless --setgroup is also specified. + +.. option:: --setgroup grouporgid + + Set gid after starting. If a group name is specified the group + record is looked up to get a gid. + +.. 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:: -m monaddress[:port] + + Connect to specified monitor (instead of looking through + ``ceph.conf``). + +.. option:: --hot-standby + + Start as a hot standby for MDS . + +Availability +============ + +**ceph-mds** is part of Ceph, a massively scalable, open-source, distributed storage system.
