       ceph-mon - ceph monitor daemon


       ceph-mon -i monid [ --mon-data mondatapath ]


       ceph-mon  is  the  cluster monitor daemon for the Ceph distributed file
       system. One or more  instances  of  ceph-mon  form  a  Paxos  part-time
       parliament cluster that provides extremely reliable and durable storage
       of cluster membership, configuration, and state.

       The mondatapath refers to a directory on a local  file  system  storing
       monitor  data.  It is normally specified via the mon data option in the
       configuration file.


       -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 specified.

       --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

       --mkfs Initialize the mon data directory with seed information to  form
              and  initial  ceph  file  system  or to join an existing monitor
              cluster.  Three pieces of information must be provided:

              · The cluster fsid.  This  can  come  from  a  monmap  (--monmap
                <path>) or explicitly via --fsid <uuid>.

              · A list of monitors and their addresses.  This list of monitors
                can come  from  a  monmap  (--monmap  <path>),  the  mon  host
                configuration  value (in ceph.conf or via -m host1,host2,...),
                or mon addr lines in ceph.conf.  If this monitor is to be part
                of  the initial monitor quorum for a new Ceph cluster, then it
                must be included in the initial list, matching either the name
                or  address  of  a  monitor  in  the  list.   When matching by
                address, either the public addr or public subnet  options  may
                be used.

              · The  monitor  secret  key  mon..  This must be included in the
                keyring provided via --keyring <path>.

              Specify a keyring for use with --mkfs.


       ceph-mon  is  part  of  Ceph,  a   massively   scalable,   open-source,
       distributed  storage  system. Please refer to the Ceph documentation at for more information.
