Hello there. I'm trying to get a xfs LVM partition to work within a domU. It works quite happily when mounted on the dom0, but fails with the following error when tried within the virtual machine:

attempt to access beyond end of device
sda6: rw=0, want=19535249408, limit=2355380224

Now this is a large LVM partition (9.1T formatted) which might have something to do with it?

Using blockdev I can see different results between the dom0 and domU:

domU:
blockdev --getsize64 /dev/sda6
1205954674688

dom0:
blockdev --getsize64 /dev/vg2/video
10002047696896

Both the machines are running Debian 4 (stable), with the kernel being 2.6.18-6-xen-686 and 2.6.18-6-xen-vserver-686.

Any ideas would be gratefully received.

Thanks in advance...
