Hi Jhon,
Thanks for the replay..........
As you said from log that, node getting fenced (reboot) due to link is
down.But the there is no problem with network connectivity. Actually
when i relocate cluster application from one to another (oracle),the
node who runs application is reboot. Both nodes are connected with cross
cable for heartbeat link and that is why it is showing link down in logs.
Regards,
Viral Ahire

I hope you're planning to expand to least a 3 node cluster before you go
into production. You know two node clusters are inherently unstable,
right?I assume you've read the architectural overview of how the cluster
suite achieves quorum.
A cluster requires (n/2)+1 to continue to operate. If you restart or
otherwise remove a machine from a two node cluster, you've lost quorum
and by definition you've dissolved your cluster while you're in that state.
Unless the special case two_node="1" is in use, and it is here:
<cman expected_votes="1" two_node="1"/>
This allows for maintaining quorum when only one vote is present.
Fencing is occurring because the link is dropping. See below:
I'm pretty sure the behavior you are describing is proper.

Hi,
I have configured two node cluster on redhat-5. now the problem is
when i relocate,restart or stop, running cluster service between nodes
(2 nos) ,the node get fenced and restart server . Other side, the
server who obtain cluster service leave the cluster and it's cluster
service (cman) stop automatically .so it is also fenced by other server.
I observed that , this problem occurred while stopping cluster service
(oracle).
Please help me to resolve this problem.
