There is a DRBD-users mailing list, but I suspect there is a lot of
overlap here.

Hi all,
(If this is not the correct mailinglist for asking this question I
apologize...maybe you could then give me a hint where this might fit
better.)
I've setup a test cluster with Debian Wheezy, pacemaker/corosync, drbd
dual primary and Xen on top of this. I know I should configure STONITH;
up until now I just didn't do this because it's a test environment.
Wrong assumption (though a common one). The idea of a test cluster is to
get things working. Fencing is a _critical_ part of this. When I started
clustering, I made the exact same assumption. I wasted weeks trying to
get even basic stuff working.
Only when I went back and added fencing did everything start to work.
Please take the time to set it up now!
The order I recommend is;
1. Get pacemaker/corosync working.
2. Configure and test stonith
3. Setup DRBD and use 'crm-fence-peer.sh' fence handler and set the
fence policy to 'resource-and-stonith'.
4. Configure resources
It's amazing how oddly and unpredictably things break without _working_
fencing.
