I'm running CentOS 6.4 with pacemaker 1.1.8. After upgrading drbd-utils84 
and kmod-drbd84 from 8.4.2 to 8.4.3, I am unable to promote the drbd 
resource on either node. If I use drbdadm primary r0 on one node, pacemaker 
demotes it. It's perpetually stuck in slave/slave mode.

[root at test-iscsi-1 ~]# service drbd status

Has something changed between the versions that I missed?
