Good Morning Dejan,

Thank you for your input, will increase the time out to 60 sec. I guess
we have switched the other machine off (pull the plug we did), the
fencing was strapped to "ilore", i guess since there was no supply to
node2, HP ilo2 did not function, so node 1 could not reach it. 

Pull the plug with ilo as the fencing method was a dump thing to do i
guess. 

So in a scenario where the node1 cannot reach the other fencing device
will break the cluster?   

extract of a mail form the group.

I guess the answer for my question is "yes". Correct me if i am wrong.

If this is the case, for some reason, if i had to replace the node 2
when node1 is dc, could break the cluster right, coz the fencing device
will be unreachable.


Please do let me know if there were any another anomalies.


Thank You,

Warm Regards

Abhin
