gfsd - Gfarm filesystem daemon
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.
-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.
