[Pacemaker] drbd doesn't work on simple 2-node cluster.

Hello Alexandr,

I came from a 3-node cluster, so i had  symmetric-cluster="false" 
configured.
But things did not work and I went back to a 2-node situation just to 
check if that was still working. My 2-node setup was working but with  
symmetric-cluster="true".
I forgot about it. So puting this back and removing  
target-role="Started" from the MS-resource did the trick.
As I understand when you tell the cluster it is symmetric it knows there 
are two nodes, and figuring out where to put the MS resource is not so 
difficult.
But when there are more then two nodes, the cluster is not symmetric 
anymore, you have to configure where to put the MS resource as i 
understand from Andrews answer.
The thing about not to configure target-role="Started" is not clear to 
me, but i gues it has something to do the 'order' thing where the ms 
resource gets promoted.
