There are some specific events that must occur in order to make NFS
server failover happen. You should search the mailing list archives for
the linux-ha software (a.k.a., heartbeat) for further details. NFS
server failover has been detailed there quite extensively over the past
couple of years. And if you do not use linux-ha for clustering
(especially in the context you describe here), I suggest you give it a
try.
