Description of problem:
During the recent cluster training, we setup an NFS service. Then client mounts
were setup to run scripts which were tar-ing on/off this nfs mount.
Performing service relocations seemed to work fine. However if we power cycled
the cluster member serving the cluster service, in about 1/3 of the cases the
client would encounter stale file handles. When this happened the only remedy
from the client's perspective was to manually remount.
Version-Release number of selected component (if applicable):
Steps to Reproduce:
1.Setup nfs service
2.mount on client, initiate exercisers on client (e.g. tar)
3.power off active nfs server cluster member
Actual Results: About 1/3 of the time nfs stale file handles occurred.
Expected Results: Transparent failover.
Fix in pool. Awaiting testing from different developers before closing.
