I can't remember though if this is enforced or not though.
NFS client side failover is for read-only exports. No way to strictly enforce since the NFSv2/v3 protocols don't have support. The client attempts to ensure that active files "look" the same when failing over. NFSv4 has migration support such that a filesystem can move between servers but the administrative model is for that: movement and not server failover.
