We don't yet have the new kernel modules needed to build the DRBD kernel module. In the meantime, you can try booting your old kernel that will work with your DRBD kernel module. initrd and the kernel used to boot are referenced via symlinks in /boot. you can try this to boot your old kernel.
cd /boot
ln -is vmlinuz-2.6.32.43-0.4.1.xs1.8.0.835.170778xen vmlinuz-2.6-xen
ln -is initrd-2.6.32.43-0.4.1.xs1.8.0.835.170778xen.img initrd-2.6-xen.img

I tried this. But now the server boots with a kernel panic.
I think this update did more than only a kernel update.
Probably some module got changed as well.

Also boot option safe and fallback result in a kernel panic

So to at least have a bootable system I booted using menu.c32
edited the boot string to the updated kernel and initrd
Now at least it boots and I can restore the symlinks to the working kernel, but not working drbd

Attached is a DRBD kernel module built against your newer kernel. This should solve your problem. A new ha-lizard release is expected next week which will include support for the latest xenserver kernel 2.6.32.43_0.4.1.xs1.8.0.839.170780xen

If you have trouble with the attached - please email.

Thanks!

The second server is now up and running again and just finshed the sync.
What I did notice is that the sync went a lot faster than the previous time. This time it could sustain a transfer rate of 60mBps

Immediatly I have a second question.
Now I want to update the first server as well.
This one is now the master.
How can I best switch between master and slave so there is as little as possible, or prefereably no downtime for the VM's?
