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

[Johan Verrept]

I am unsure this is the source of your problems, but I think you have a
colocation restraint too much.

> colocation co.ms.drbd.mysqlstack_on_res.ip.mysql inf:
ms.drbd.mysqlstack res.ip.mysql 

Why this?

You already force both ms.drbd.mysqlstack and res.ip.mysql onto
ms.drbd.mysqldb:Master, so there is no need to force ms.drbd.mysqlstack
onto res.ip.mysql too.
