[ClusterLabs] Fencing one node kill others

[Alfonso Ali]

Hi,

I have a four node cluster that uses iLo as fencing agent. When i simulate
a node crash (either killing corosync or echo c > /proc/sysrq-trigger) the
node is marked as UNCLEAN and requested to be restarted by the stonith
agent, but everytime that happens another node in the cluster is also
marked as UNCLEAN and rebooted as well. After the nodes are rebooted they
are marked as online again and cluster resume operation without problem.

I have reviewed corosync and pacemaker logs but found nothing that explain
why the other node is also rebooted.

Any hint of what to check or what to look for would be appreciated.
