       gfarm_agent - Gfarm Filesystem Metadata Cache Server


       gfarm_agent [ options ]


       gfarm_agent  is  a cache server for a Gfarm metadata server that can be
       shared by multiple hosts and multiple users.  The cache server  greatly
       improves  performance  and  response  time  for  a  Gfarm filesystem by
       reducing network communication to a distant metadata server.

       Any number of gfarm_agents can be running on different nodes  (or  even
       on  the  same node) at the same time.  Consistency among multiple cache
       servers and a metadata server is maintained.


       -L log-level
              Specifies a log priority level.  The log output, which  priority
              is  higher  or  equal  to  this level, will be sent to syslog or
              standard error.  Please refer  gfarm.conf(5)  for  the  priority
              levels which can be specified by this option.

       -P pid-file
              Specifies   a   file  name  which  records  the  process  ID  of

       -S syslog-facility
              Specifies  a  syslog  facility  used   to   report   errors   by
              gfarm_agent.  By default, local0 is used.

       -d     Specifies  the  debug mode.  gfarm_agent runs in the foreground,
              not in the background.

              If this option is specified and -L is  not  specified,  the  log
              level is set to "debug".

       -f config-file
              Specifies  a  configuration  file  that  is  read instead of the
              default configuration file.

       -m     Specifies  the  master  mode.   This  improves  metadata  access
              performance  by  caching  the  path information.  This option is
              only available when there is a single gfarm_agent running.

       -p port-number
              Specifies a port number for TCP, to be used by gfarm_agent.

       -v     Displays verbose error messages in authentication.

       -?     Displays a list of command options.
