gfmd

Name

gfmd(8) -- Gfarm metadata server

Synopsis

gfmd [options]

DESCRIPTION

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.

In order to execute gfmd as a non-privileged user process, a configuration file for a user needs to be specified by the -f option. At the very least, the port number used by gfmd should be altered to a non-privileged port number by the metadb_serverport statement in the configuration file or by the -p option.

In this case, the altered port number for gfmd should be specified by the metadb_serverport statement in ~/.gfarmrc or in %%SYSCONFDIR%%/gfarm.conf on a client node.

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 gfarm.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.

-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. By default, 601 is used.

The default port requires root privileges, although privileged ports are not necessary to execute gfmd.

-s syslog-facility

Specifies a syslog facility to report errors encountered by gfmd. By default, local0 is used.

-u

Specifies a syslog facility to report errors encountered by gfmd. By default, local0 is used.

-?

Displays a list of command options.
