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

NAME
       mfsmetalogger  -	 start,	 restart  or stop Moose	File System metalogger
       process

SYNOPSIS
       mfsmetalogger [-f] [-c CFGFILE] [-u] [-d] [-t LOCKTIMEOUT] [ACTION]

       mfsmetalogger -s	[-c CFGFILE]

       mfsmetalogger -v

       mfsmetalogger -h

DESCRIPTION
       mfsmetalogger is	the metadata replication server	of Moose File  System.
       Depending  on parameters	it can start, restart or stop MooseFS metalog-
       ger process.  Without any options it starts MooseFS metalogger, killing
       previously run process if lock file exists.

       SIGHUP (or 'reload' ACTION) forces mfsmetalogger	to reload all configu-
       ration files.

       mfsmetalogger exists since 1.6.5	version	of MooseFS; before  this  ver-
       sion mfschunkserver(8) was responsible of logging metadata changes.

       -v     print version information	and exit

       -h     print usage information and exit

       -f     (deprecated, use start action instead) forcily run MooseFS meta-
	      logger process, without trying to	kill previous  instance	 (this
	      option  allows  to  run MooseFS metalogger if stale PID file ex-
	      ists)

       -s     (deprecated, use stop action instead)  stop  MooseFS  metalogger
	      process

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

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

       -d     run in foreground, don't daemonize

       -t LOCKTIMEOUT
	      how long to wait for lockfile (default is	60 seconds)

       ACTION is the one of start, stop, restart, reload, test	or  kill.  De-
	      fault action is restart unless -s	(stop) or -f (start) option is
	      given.  Note that	-s and -f options are  deprecated,  likely  to
	      disappear	 and  ACTION parameter to become obligatory in MooseFS
	      1.7.
