We had configured RHEL 6.2 - 2 node Cluster with clvmd + gfs2 + cman + smb.
We have 4 nic cards in the servers where 2 been configured in bonding for
heartbeat (with mode=1) and 2 been configured in bonding for public access
(with mode=0). Heartbeat network is connected directly from server to
server. Once in 3 - 4 days, the heartbeat goes down and comes up
automatically in 2 to 3 seconds. Not sure why this down and up occurs.
Because of this in cluster, one system is got fenced by other. 


Is there anyway where we can increase the time to wait for the cluster to
wait for heartbeat. Ie if the cluster can wait for 5-6 seconds even the
heartbeat fails for 5-6 seconds the node won't get fenced. Kindly advise.
