Hi, I use DRBD 0.7.21-4 and HA 2.1.2 in order to have a master-slave-configuration on two nodes. We have a drbd master/slave resource and a resource group including an IPAddr.
The drbd master should move to the slave node if any service in the group
fails and the group must run only on the drbd master
Currently, the master is not moved, if the group fails.

I tried your suggestion adding the symmetrical=true value:
<rsc_order id="drbd_before_group" from="group" to="ms_drbd" action="start"
to_action="promote"/>
<rsc_colocation id="group_on_drbd" from="group" to="ms_drbd" to_role="Master"
symmetrical="true" score="INFINITY"/>
In result both systems could be started BUT both became slave!
cat /proc/drbd:
cs:Connected st:Secondary/Secondary ld:Consistent
crm_mon:
Master/Slave Set: ms_drbd
drbd0:0 (heartbeat::ocf:drbd): Started frigg
drbd0:1 (heartbeat::ocf:drbd): Started odin
Resource Group: group
IPaddr0 (heartbeat::ocf:IPaddr): Started frigg
MailTo (heartbeat::ocf:MailTo): Started frigg
Without a master I cannot access to the DRBD ressources.
Secondly, how the group could be started? The group normally starts at the
master -- and there is none...
Thanks for your help!
