[Pacemaker] Cannot get "order" constraint to work.

[Stratos Zolotas]

As you can see in the config, I have a group named mysql that includes
fs_mysql, ip_mysql, mysqld, apache primitives.

The expecting result is to start this group after ms_drbd_mysql is promoted
to one of the nodes.

Is this wrong? Should I try a different approach?
