[ClusterLabs] HA problem: No live migration when setting node on standby

[Philip Schiller]

hank you for the reply.

I added the following line to crm configure:

colocation colo_pri-vm-alarmanlage-drbd-jabber_master inf: pri-vm-jabber:Started mas-drbd-jabber:Master

This doesn't change anything though. Here some output of crm_mon:

   * pri-vm-alarmanlage    (ocf:heartbeat:VirtualDomain):     Started s1

The wierd thing is, that if i put my node back online it unmigrates perfectly.
Do i need more constrains? If you need any more information about setup/confs i am happy to provide them.

Philip.
