it seems on the new versions of corosync/pacemaker you will have to specify
monitor interval for both master and slave drbd resource. I had this problem
before but not sure if you are having the same.

Subject: [Pacemaker] drbd doesn't work on simple 2-node cluster.
Hi,
I'm trying to install a simple 2-node cluster, drbd/failover-IP/filesystem.
Followed the usual examples, wich are mostly the same. I got this working
before, but now it doesn't work anymore.
The problem (i think) is this (from de log):
Feb 9 14:03:04 test1 pengine: [5152]: notice: clone_print: Master/Slave

Why can't my drbd not run anywhere? Must I tell my the drbd-resource which
nodes it can use or something?
(PS the drbd alone without the cluster-stuff is working)
My config:

Thanks in advance for your help.
