Hi all,
Setup:
Cluster Suite 5
2 Nodes each fenced by DRAC card over network interface. Flagged as two
node in cluster.conf
<cman expected_votes="1" two_node="1"/>
As a test, I unplugged one node (Node A) from the network. The
remaining node (Node B) attempted to fence it, but failed (no network
access) and never assumed the services. Plugging in Node A a gain
induced each to fence the other. Something similar happens when a node
is rebooted manually (shutdown -r now).
How does one best combat this? I've seen reference to adding a ping
node but no actual documentation on how to do it.
Thanks,
Chris

Hi Chris,
Here's a good place to start:
http://sources.redhat.com/cluster/faq.html#quorum
There's a couple FAQ entries after that one too pertaining to tie-breaking.
