mfsmaster(8)		    This is part of MooseFS		  mfsmaster(8)

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  mfs-
	      master.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 sec-
	      onds)

       -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 run-
	      ning". The kill action will send a SIGKILL to the	currently run-
	      ning master process. SIGHUP or reload action forces mfsmaster to
	      reload  all  configuration files.	restore	tries to restore meta-
	      data file	using backup metadata files and	 changelogs;  if  suc-
	      cessful  it will store recovered metadata	file end stop, it will
	      never start master process.
