[Linux-cluster] Fence Issue on BL 460C G6

[Dustin Henry Offutt]

I believe your problem is being caused by "nofailback" being set to "1". :

                       <failoverdomain name="Failover" nofailback="1"
ordered="0" restricted="0">

Set it to zero and I believe your problem will be resolved.
