That is not the same. DRBD behaves differently from "normal" shared
storage, and can recover from concurrent activation differently; either
automatically or by manually mer

Hi,
I'm using pacemaker-1.1.10.
When a pacemaker's process crashed, the node is sometimes fenced or is not

Is this the assumed behavior?

Hi Jacobo,
1) corosync communicates through 2 ports, don't forget the second one.
2) IMHO, when you block both ports, it's like a classical split brain.
I've done it to test split brain and hopefully fencing behaviour.

Thanks Andreas for your kind answer, I'll add this to my test battery.
Also, my other question, is it a good idea to close the corosync port?
Should corosync behave in a expected way? I am getting odd behaviors on
this one, but not sure if where to put the blame.
Thanks in advance.
