Hello, everybody
I installed nfs on my cluster system, two head nodes(one is primary and another is backup) with two clients. They use NFS to store and transfer data between server and clients. But whenever failover happens, the client can't connect to backup server although
backup server has the same IP and hostname and same configuration at that time.
"NFS server is not responding, still trying"
I use this command: #service nfs restart on backup server, it is not useful.
What should I do on backup server so that client can get connection with it? By the way I use Pfilter (iptables) on both servers.
Thank you
Eric

There are some specific events that must occur in order to make NFS
server failover happen. You should search the mailing list archives for
the linux-ha software (a.k.a., heartbeat) for further details. NFS
server failover has been detailed there quite extensively over the past
couple of years. And if you do not use linux-ha for clustering
(especially in the context you describe here), I suggest you give it a
try.
