gfsd - Gfarm filesystem daemon
is a filesystem daemon for the Gfarm filesystem, which runs on every
filesystem node, usually, with root privileges.
provides remote file operations with access control in the Gfarm
filesystem as well as user authentication, file replication, and node resource
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.
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.
Specifies a file name which records the
process ID of gfsd.
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
When the -c
option is specified twice (or the -cc
file copies that are not registered in the metadata server are deleted.
When the -c
option is specified three times (or the -ccc
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.
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
Specifies a configuration file that is read
instead of the default configuration file.
Specifies my own canonical host name.
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.
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.
Specifies a syslog facility to report errors
by gfsd. By default, local0 is used.
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.
