[Fedora-xen] Using large disk in DomU

[Robin Bowes]

Hi,

I'm running Xen 3.0.3 on FC6 with FC6 DomU guests.

On the Dom0 machine, I have 8 x 500GB disks running as a RAID6 array
with lvm on top of that. There is one partition available:
/dev/vg_media/lv_media which has an ext3 FS on it.

I want to make this available to a DomU guest, so I put this in the xen
config file:

disk = [ 'phy:/dev/vg_host/lv_slim,xvda,w',
         'phy:/dev/vg_media/lv_media,sda1,w', ]



The disk appears in the DomU guest, but if I fsck it, this is what I see:

# fsck /dev/sda1
fsck 1.39 (29-May-2006)
e2fsck 1.39 (29-May-2006)
The filesystem size (according to the superblock) is 732575744 blocks
The physical size of the device is 195704832 blocks
Either the superblock or the partition table is likely to be corrupt!
Abort<y>? yes

Any idea what's going on here? Am I doing something wrong?
