Please go to 1.1.5, at least, as soon as you can.

Rather than having all those individual clones and constraints between
them, you can greatly simplify your configuration with a cloned group:

primitive p_dlm_controld ocf:pacemaker:controld \
	op start interval="0" timeout="90" \
	op stop interval="0" timeout="100" \
	op monitor interval="10"
primitive p_o2cb ocf:pacemaker:o2cb \
	op start interval="0" timeout="90" \
	op stop interval="0" timeout="100" \
	op monitor interval="10"
primitive p_fs_ocfs2 ocf:heartbeat:Filesystem \
  params device="<your drbd device>" \
    directory="<your mountpoint>" \
    fstype="ocfs2"
group g_ocfs2 p_dlm_controld p_o2cb p_fs_ocfs2
clone cl_ocfs2 g_ocfs2 \
	meta interleave="true"

You'll still need that one order and colo constraint linking your cloned
group to the DRBD master/slave set, of course.

And if you're getting an OCF_ERR_INSTALLED error from
ocf:pacemaker:o2cb, then there definitely will be an error message in
the logs preceding that.

grep -E 'o2cb.*ERROR' /var/log/{messages,syslog}

Hope this helps.

Cheers,
Florian
