From Linux NFS

As the number of fileservers in a FedFS domain grows, administering them by logging in to each and running a command line tool becomes challenging. FedFS therefore provides an RPC mechanism for handling administrative tasks remotely. FedFS administrators use this mechanism to manage junctions and NSDB connection parameters remotely.
Since the RPC interface duplicates operations that can also be done via command line on the server, it is entirely optional. The equivalent command line tools are the nfsref command and the nsdbparams command.
Set up rpc.fedfsd
On Fedora 19, to enable this interface on Linux NFS servers, simply start rpc.fedfsd:
# systemctl enable rpcfedfsd.service # systemctl start rpcfedfsd.service
If your distribution doesn't provide fedfs-utils, after installing with "make install," check the fedfs-utils-0.9/contrib/init directory for an appropriate init script for your Linux distribution.
In fedfs-utils-0.9, the administrative tools that contact this server are commands such as fedfs-create-junction and fedfs-get-nsdb-params. These are simply commands that perform a single RPC against a remote FedFS administrative server. In fedfs-utils-0.9, these remain a primitive mechanism meant for scripting or unit testing.
