       gfsd(8) - Gfarm filesystem daemon


       gfsd [ options ]


       gfsd  is  a  filesystem  daemon for the Gfarm filesystem, which runs on
       every filesystem node, usually, with root privileges.

       gfsd provides remote file operations with access control in  the  Gfarm
       filesystem  as  well as user authentication, file replication, and node
       resource status monitoring.

       It is possible for  gfsd  to  be  executed  as  a  non-privileged  user
       process,  although  only  the  user  that  executes  the  gfsd  can  be
       authenticated.   Other  users  cannot  use  it.    For   details,   see
       SETUP.private.en document.


       -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 gfarm2.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 gfsd.

       -c     When starting up, gfsd investigates all files stored in a  spool
              directory.   This  option  is  useful  when a hostname of a file
              system node is changed.   Valid file copies will  be  registered
              to the metadata server.

              When  the  -c  option  is specified more than once, invalid file
              copies that are  not  registered  in  the  metadata  server  are

       -d     Specifies  the  debug  mode.  With the -d option, gfsd runs as a
              foreground process, not a daemon.

              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.

       -h hostname
              Specifies my own canonical host name.

       -l IP-address
              Specifies the IP address from which the gfsd accepts TCP and UDP
              requests.   The default address is all IP addresses of the host.
              This option is useful to invoke multiple instances  of  gfsd  to
              provide multiple spool directories on the host.

       -r directory
              Specifies  a  spool  directory  for  a  Gfarm filesystem on this
              filesystem node.

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

       -v     Makes  gfsd  output verbose log message on authentication.  This
              is  useful,  when  one  has  to  resolve  an  issue  about   GSI

       -?     Displays a list of command options.
