Maybe before diving deeper into stuff and posting configs: it just 
occured to me that I could start all DRBD resources from the init script 
and put them primary.

So basically I'm wondering what the added value is of having DRBD things 
controlled by Pacemaker if the resources are primary all the time 
anyway. (This is a Xen cluster by the way).
Maybe the risk of putting them secondary by accident?
