There are numerous threads in the NFS mailing list archives (and 
probably in the NFS HOWTO - it's been quite a while since I've read it) 
on how to set up a HA NFS cluster. Yes, there are quite a few pitfalls 
to watch for and some applications may not behave well in this 
configuration, but it's definitely achievable.

Yes, good clarification.
