LVM Name Changed?

[George Magklaras]

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 ?
