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

       -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 or kill.
              Default action is restart. The test action will yeld 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.
