We have a Red Hat 5.1 cluster connecting to a GFS filesystem on a SAN. We are experiencing difficulties with the cluster regularly and it tends to crash and not always failover properly. We are attempting to deal with these machine panics, but in the meantime we are ending up finding lots of stale NFS mounts on client servers that are a pain to find - Generally only find them when the user comes to us and they ain't happy at that point.
What I was hoping to do was to have a utility or perhaps a script that can check any mounts from clients to see if they are considered stale or not after a crash occurs. That way if I could generate a list of stale mounts then I can manually sort them out prior to the user seeing the problems.
If anyone knows of such a utility or has such a script I would be much in your debt.
Thanks in advance
