mfsmaster - start, restart or stop Moose File System master process
mfsmaster [-c CFGFILE] [-u] [-i] [-a] [-e] [-x[x]] [-t LOCKTIMEOUT] [ACTION]
mfsmaster is the master program of Moose File System.
- print version information and exit
- print usage information and exit
- -c CFGFILE
- specify alternative path of configuration file (default is mfsmaster.cfg in system configuration directory)
- log undefined configuration values (when default is assumed)
- run in foreground, don't daemonize
- -t LOCKTIMEOUT
- how long to wait for lockfile (in seconds; default is 1800 seconds)
- 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.
- automatically restore metadata from change logs
- start without metadata (usable only in pro version - used to start additional masters)
- produce more verbose output
- even more verbose output
- 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.
