Are these RHEL derived file servers (inc. CentOS and Rocks),
or others ?
I ask because we've found that RHEL ext3 doesn't
cut the mustard as an NFS server and long ago switched
to Debian and XFS for our NFS server for our clusters.
Not to say that pathological I/O patterns can't cause
it problems (we had one on Friday for instance), but
the RHEL box couldn't cope with our normal load..
