[DRBD-user] Weird HA-behavior with XEN/HA/DRBD/LVM

I have a HA-setup with Xen heartbeat lvm and DRBD. According to this howto:
http://www.asplund.nu/xencluster/xen-cluster-howto.html

Im using 2 Poweredge R710. ha1 & ha2 with Ubuntu 8.04

I can do a manual live migration of the domU's without any problems. Also if
i shutdown heartbeat on ha1 with init.d/heartbeat the domU's are migrated to
ha2 sucessfully.

Also, if i pull the plug on ha1, after a while the domU's start on ha2 (as
they should).

However! When doing a "reboot" on ha1, domU's begin to migrate but then
crashes on ha2. pasting ha-debug and xend.log below.

Any ides why it keeps doing this? All i can think of is that some process is
being killed to fast (when the domU's are beeing migrated, but i don't know
what to look for.) Also, i ran a test couple of weeks ago with the same
setup but on one R710 and a older shuttle and then there was no problem.
Tried to redo the howto twice but with the same problem

Cheers! /Sussox
