RedHat Cluster Failover issue.

S.M.Athar — Sat, 14 Aug 2010 12:00:28 GMT

Hello,
I successfully create 2 node cluster and define only IP Services (DB peoples working on Database). I created Quorum,Fencing with ilo and also created failover domain. Now I am facing problem when I am checking failover of nodes. When I rebooted my active node, my IP resource moves to the 2nd node and also show active, but after sometimes a message appears on console :-
dlm: closing connection to node 1

Message from syslog
node1 clurgmgrd# Quorum Dissolved
dlm: got connection from 1

and I lost the response from the IP resource.
Please help.
My resource is running currently on node2 mean node2 is active.

What kind of Linux? OS Version? What clustering solution did you implement? From the error message I think it's a pacemaker cluster.

Thanks for your reply. OS is RHEL 5.5 and I am using RHCS for Oracle Database clustering.
Now my cluster is working fine. Quorum dissolved issue is due the quorum disk service was not working on one of the node. Successfully check the failover too.
Thanks
Athar
