       ceph-mds - ceph metadata server daemon


       ceph-mds -i name [[ --hot-standby [rank] ]|[--journal_check rank]]


       ceph-mds  is  the metadata server daemon for the Ceph distributed file system. 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 or journal-check, 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.


       -f, --foreground
              Foreground:  do  not daemonize after startup (run in foreground). Do not generate a
              pid file. Useful when run via ceph-run(8).

       -d     Debug mode: like -f, but also send all log output to stderr.

       -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.

       -m monaddress[:port]
              Connect to specified monitor (instead of looking through ceph.conf).


       ceph-mon  is  part  of  the Ceph distributed file system. Please refer to the Ceph wiki at for more information.
