You must have fencing configured.
CentOS 6 uses pacemaker with the cman plugin. So setup cman
(cluster.conf) to use the fence_pcmk passthrough agent, then setup
proper stonith in pacemaker (and test that it works). Finally, tell DRBD
to use 'fencing resource-and-stonith;' and configure the
'crm-{un,}fence-peer.sh' {un,}fence handlers.
See if that gets things working.
