Description Tim Burke 2002-04-09 15:13:08 UTC

From Bugzilla Helper:
User-Agent: Mozilla/4.78 [en] (X11; U; Linux 2.4.7-10 i686)

Description of problem:
clumanager-1.0.9

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):


How reproducible:
Sometimes

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.
