NAME
       mfsmaster - start, restart or stop Moose File System master process

SYNOPSIS
       mfsmaster [-c CFGFILE] [-u] [-i] [-a] [-e] [-x[x]] [-t LOCKTIMEOUT]
       [ACTION]

       mfsmaster -v

       mfsmaster -h

DESCRIPTION
       mfsmaster is the master program of Moose File System.

OPTIONS
       -v     print version information and exit

       -h     print usage information and exit

       -c CFGFILE
              specify alternative path of configuration file (default is
              mfsmaster.cfg in system configuration directory)

       -u     log undefined configuration values (when default is assumed)

       -f     run in foreground, don't daemonize

       -t LOCKTIMEOUT
              how long to wait for lockfile (in seconds; default is 1800
              seconds)

       -i     ignore some metadata structure errors (attach orphans to root,
              ignore names without inode, etc.). DO NOT use unless you are
              ready to pick up the pieces. See
              https://github.com/moosefs/moosefs/issues/151 for discussion.

       -a     automatically restore metadata from change logs

       -e     start without metadata (usable only in pro version - used to
              start additional masters)

       -x     produce more verbose output

       -xx    even more verbose output

       ACTION is the one of start, stop, restart, reload, test, restore or
              kill.  Default action is restart. The test action will yield one
              of two responses: "mfsmaster pid: PID" or "mfsmaster is not
              running". The kill action will send a SIGKILL to the currently
              running master process. SIGHUP or reload action forces mfsmaster
              to reload all configuration files. restore tries to restore
              metadata file using backup metadata files and changelogs; if
              successful it will store recovered metadata file end stop, it
              will never start master process.
