       ceph-mds - ceph metadata server daemon


       ceph-mds -i <ID> [flags]


       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.


       -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.

       --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

       --setgroup grouporgid
              Set gid after starting.  If a group name is specified the group record is looked up
              to get a gid.

       -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).

       --id/-i ID
              Set ID portion of the MDS name.


       ceph-mds  is  part of Ceph, a massively scalable, open-source, distributed storage system.
