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.
