[Pacemaker] Problems with colocation/order with drbd tree-node-setup

[Johan Verrept]

Try a 

crm_resource --resource res.drbd.mysqlstack --cleanup
crm_resource --resource res.ip.mysql --cleanup

To clean up any transient errors that may clutter your cluster status.

Other than that, I have no more ideas
