[Xen-users] drbd and xen 3.0.1

[Radu Spineanu <radus@xxxxxxxxxxxx>]

Hello

I also sent this to the drbd mailing list, but maybe someone here can
help me.

I am trying to test drbd in a Xen Debian vserver, and i have a simple
drbd.conf with two nodes.

If i modprobe the module it works ok, but when i start drbd everything
crashes with:

drbd: registered as block device major 147

I have compiled the module with and without ARCH=xen and i get the same
thing.
Kernel is 2.6.12.6, xen is 3.0.1, and drbd 0.7.17.

Thanks,
Radu Spineanu
