Loss of quorum on remaining cluster node after other node fenced in RHEL 5

Solution Unverified - Updated -

Issue

  • We were testing fencing with fence_ipmilan and when the other node powered off, the remaining node (where we were running the test from) lost quorum:
# fence_ipmilan -a 192.168.2.10 -l fence -p administrator -P
Rebooting machine @ IPMI:192.168.2.10...Done
