NAME

       ceph-mon - ceph monitor daemon

SYNOPSIS

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

DESCRIPTION

       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.

OPTIONS

       -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 startup.

       --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>.

       --keyring
              Specify a keyring for use with --mkfs.

AVAILABILITY

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