What are you actually trying to do?

There's a little support for replication in that the NFSv4 server can be
told to report certain locations as having the same data, but it's not
really supported yet: you need smoething to create the replicas for you
(probably doable with GFS2 as the exported filesystem, or by sharing the
filesystem image if it's read-only). I don't think the Linux NFSv4
client knows how to use that information yet.
