Well, it seems to cope quite well. The nfs mount "hangs" for a few
seconds whilst the IP moves from one server to another (unavoidable
obviously), but it then picks up from where it was. I suspect there will
be file corruption issues with files that are partially written when the
failover happens, but I guess that can't be avoided without a client
side solution.
