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.
