To All,Looks like I got nicked by Occam's Razor when I "simplified" my cluster config file... :-) A "less simplified" version is below.
My question still stands, however. What does "cluster.conf" look like if you're trying to deploy a "highly available" NFS configuration. And, again, by "highly available" I mean that NFS Clients never get the dreaded "stale nfs file handle" message unless the entire cluster has failed.
-RZ
p.s. A better, but still simplified, cluster.conf for EL5.
