gfsd(8)

NAME

   gfsd - 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 twice (or the -cc option), invalid
       file copies that are not registered in the metadata server are
       deleted.

       When the -c option is specified three times (or the -ccc option),
       invalid file copies that are not registered in the metadata server
       are moved to the lost+found directory in the Gfarm file system.
       Furthermore, invalid metadata pointing to a missing file copy of
       the file system node are deleted. This is the default behavior.

   -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. This option can be specified multiple times to
       specify multiple spool directories up to five.

   -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.
