NFS Disconnection issue frequently
We are having one strange NFS issue in our environment. We are running sun grid engine clustering with Master node as a VM in ESXI. All other client nodes are physical Linux Servers running on SLES11. There is one share which will be shared from master node and will be accessed by all clients via nfs.
Recently we noticed that some NFS disconnection is happening intermittently between the machines and master node and so the share is getting disconnected for some time, which will result in grid engine service in client node to be offline.
We checked the logs in both server and client, but unable to get any clue regarding this disconnection. But when we run nfsstats on the server we got some info.
nfsstat -sr
Server rpc stats:
calls badcalls badclnt badauth xdrcall
2653547712 59839741 214 59839527 0
Also I ran tcpdump on the server to monitor NFS traffic and we got some errors when the disconnection is happening
"auth bogus credentials (seal broken)"
Do you ever faced this kind of nfs issues. Please help and give some suggestion for the above problem.
