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.
