Hi, I used to follow discussions in this group closely but lately I was distracted from other issues. I used to think that as a rule NFS require carefull tuning. Now I've been said that NFS v.4 takes care of most of the issues that v.2 and v.3 have and it is mounted with its defaults. The problem is that under load I see issues (like stalled file system) that I used to associate with NFS (and I'm talking about a small clusters, say 30-50 nodes). I checked the mpich home page and found the same old warnings that nfs must be carefully tuned and found nothing specific for NFS v.4. Could somebody comment on how much tuning NFS v.4 reqiere compared with NFS v.3, please? Thanks in advance, Ted
