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.
