NAME¶
gfsd(8) - 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 more than once, invalid file copies
that are not registered in the metadata server are deleted.
- -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.
- -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.
FILES¶
- %%SYSCONFDIR%%/gfarm2.conf
