gfmd - Gfarm metadata server
gfmd is a Gfarm filesystem metadata server for accessing
the filesystem metadata of the Gfarm filesystem. gfmd must be running
on a metadata server node in advance.
It is possible for gfmd to be executed as a non-privileged
user process, although only the user that executes the gfmd can be
authenticated. Other users cannot use it. For details, see SETUP.private.en
document
To access gfmd, the hostname and the port number should be
specified by the metadb_server_host and metadb_server_port statements,
respectively, in ~/.gfarm2rc or in %%SYSCONFDIR%%/gfarm2.conf on a client
node.
-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 to be used to record the process ID
of gfmd.
-S
Runs as slave forcedly, even if the gfmd is set to
default master.
-d
Specifies the debug mode. With the -d option, gfmd 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.
-p port
Specifies a port number to be used by gfmd.
-s syslog-facility
Specifies a syslog facility to report errors encountered
by gfmd. By default, local0 is used.
-t
Enables an audit log feature for file creation,
modification and removal.
-v
Makes gfmd output verbose log message on authentication.
This is useful, when one has to resolve an issue about GSI
authenticaion.
