mfsmaster -v
mfsmaster -h
Description
mfsmaster is the master program of Moose File System. Depending on parameters it can start, restart or stop MooseFS master process. Without any options it starts MooseFS master, killing previously run process if lock file exists.
SIGHUP (or 'reload' ACTION) forces mfsmaster to reload all configuration files.
- -v
- print version information and exit
- -h
- print usage information and exit
- -f
- (deprecated, use start action instead) forcily run MooseFS master process, without trying to kill previous instance (this option allows to run MooseFS master if stale PID file exists)
- -s
- (deprecated, use stop action instead) stop MooseFS master process
- -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)
- -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. Default 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.
