[ClusterLabs] can't start/stop a drbd resource with pacemaker

Hi,

i'm new to HA-cluster. I'm currently establishing a two-node cluster and playing around with it.
I habe a primitive drdb resource and a corresponding ms one:

crm(live)resource# status

 Master/Slave Set: ms_drbd_r0 [prim_drbd_r0]
     Masters: [ sunhb58820 ]
     Slaves: [ sunhb65278 ]


Starting or stopping drbd with start/stop does not work neither for the ms ressource nor for the primitive.
If i try to stop it keeps running. Also if i do a cleanup before (for both resources).
Which resource should i stop first ? The primitive or the ms ?
I tried both, but none worked. Other resources, like an ip, can start/stop with crm.
When i change the target-role of of the primitive via "crm configure edit" and commit that, it starts/stops immediately.
But that can't be the prefered way to start/stop a drbd resource ?

If you need more information ask me.

Thanks.


Bernd
