[Pacemaker] pacemaker 1.1.6

[emmanuel segura]

I was doing a nic firmware upgrade and i forgot to stop the cluster on node
where i was working, but something strange happened, both node are fenced
at the same time.

I'm using sbd as stonith device, with the following parameters.

watchdog time = 10 ; msgwait 20 ; stonith-timeout = 40(pacemaker)
