NAME

       gfsd(8) - Gfarm filesystem daemon

SYNOPSIS

       gfsd [ options ]

DESCRIPTION

       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.

OPTIONS

       -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 deleted.

       -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 authenticaion.

       -?     Displays a list of command options.
