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

       -F log-file
           Specifies a log file.

       -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.
