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.
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

Specifies the debug mode. With the -d option, gfsd runs as a

Specifies my own canonical host name.
Specifies the IP address from which the gfsd accepts TCP and UDP
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.
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 authenticaion.
