Here it is: http://p.0wnz.at/205018
The global_common.conf is used as shipped. This is the same config I  
use with lower versions.

Yes I did. Thanks Roman for that. I was not aware that FP1 is such a mess.

Ok, I did that. I compiled latest snapshot 8.3.9-5. However both  
version 8.3.8.1 and 8.3.9-5 crash when running drbd-overview after  
making my first node to primary. No problem with drbdadm command so  
far. Note that my drbd resource comes up with secondary/secondary.  
This is a completely new resource, I try to initialize for use with  
Xenserver. Before running drbd-overview I was able to cat /proc/drbd  
and saw the first node being primary then for my resource.

Unfortunately for both 8.3.8.1 and 8.3.9-5 Xenserver is not able to  
write a crash info to /var/crash. For version 8.3.9 Xenserver was able  
to do it.
