[DRBD-user] Keeping node as primary on NW connection loss

[Stephen Childs]

I have Xen VMs running on LVM backed by DRBD. Periodically, I lose the 
network connection and the following occurs:

  * Primary is demoted to secondary
  * LVM loses its volumes
  * Xen VMs lose backing store and die!

Is there any way to ensure that when the connection is lost, the primary 
node stays as primary (or at least that LVM and Xen can remain active)? 
I'm fine with having to do some manual fixup as long as the primary 
remains primary.

I have read through man pages and user guide but can't seem to find 
anything directly relevant.

I have attached the logs of the incident from both nodes along with the 
output of "drbdsetup /dev/drbd0 show"
