I think you have fencing-race problem, try to look man fence_drac6
try to delay fencing on a node when have problem with the cluster network
=======================================
--delay
Wait X seconds before fencing is started (Default Value: 0)
========================================
And i see you don't have a quorum disk, using qdisk for redhat it's always
a good idea
