Hi guys,

I have kernel 3.1.5 + Debian 6 + Xen 4.1.1 and a problem with remus disk synchronization:

Remus without disk replication works well: # remus -i 100 ubuntu backup-host …that shows a continual stream of messages and HA works.
Trying to add disk replication: disk=['tap2:remus:192.168.2.4:9000|aio:/remus/ubuntu.img,xvda,w']
1 creating domain: #xm create ubuntu.cfg
2 starting remus script: # remus -i 100 ubuntu 192.168.2.4

ubuntu.img = 2.1G

Now it has taken over 2 hours doing "nothing", remus doesn't show any message stream. On the backup host ubuntu appears in Pause state,

and on the primary it seems to be working as xm list shows the guess in - - - - - - NO state. The CPU time does not increse either.
I wonder what might be happening or what am I doing wrong since I can't see any logs or futher information from both of my systems.

I have uploaded a screenshot: http://i42.tinypic.com/2whl8wk.png

Thank you in advance!

Tony.
