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


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

       mfsmaster -v

       mfsmaster -h


       mfsmaster is the master program of Moose File System.


       -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

              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
     for discussion.

       -a     automatically restore metadata from change logs

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

       -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.
