Well rebooting a server lasts 2 minutes approximately. 
I think I'm going to keep the same workaround I have on other servers:

-set crm stonith-timeout=300s
-have a "sleep 180" in the fencing script, so the fencing will always last 3 minutes

So when crm fences a node on startup, the fencing script will return after 3 minutes. And at that time, the other node should be up and it won't be retried fencing

What you think about this workaround?

The other solution would be updating pacemaker, but this 1.1.14 I have tested on many servers, and I don't want to take the risk to update to 1.1.15 and (maybe) have some other new issues...

Thanks a lot!
