This defines an NFS server resource. The NFS server
resource is useful for exporting NFSv4 file systems
to clients. Because of the way NFSv4 works, only
one NFSv4 resource may exist on a server at a
time. Additionally, it is not possible to use
the nfsserver resource when also using local instances
of NFS on each cluster node.

<longdesc lang="en">
Specifies the port number used for RPC listener sockets. If
this option is not specified, rpc.statd chooses a random
ephemeral port for each listener socket. This option can be
used to fix the port value of its listeners when SM_NOTIFY
requests must traverse a firewall between
clients and servers.
