What can you see under the /dev/mapper directory? I recall seeing this
issue with a similar hardware config and the advice was to upgrade to
the latest release due to some issues with LVM. The problem however was
that there was fs corruption (changing manually the fstab entry did not
mount the fs in a clean way). Can you mount root on the system disk if
you change the fstab to /dev/vg0/root ?
