Hello,

I am not seeing any DRBD issue whatsoever in your logs. You probably
want to post this to the linux-ha mailing list. Where you're sure to be
told that your Heartbeat 1-style configuration is obsolete and you
should be using Pacemaker instead. :)

And, when you post to linux-ha, be sure to explain what your
/etc/ha.d/resource.d/xendomainsHA2 script does.

Cheers,
Florian
