Be sure you configured "resource-and-stonith" fencing policy for DRBD
and you use a correct fencing script like: goo.gl/O4N8f

Bad idea! You should really use stonith in such a setup ... in any
cluster setup.

colocation col_ocfs2 inf: .......

Use "crm configure help colocation" to find out more, the same for order.

You could also add the two file system primitives to the cl_ocfs2_mgmt
group, then only the constraints between this group and DRBD are needed.
