Default lvm2 boot failure

Hi list,

My server doesn't boot after raid card faliure. I recreated the raid1
array, partitioned and copyed the whole system to it. Then executed lilo
-v .


I did this with an ubuntu live cd.
My system looks like:

--------

and the error message or something that fails the boot? is it bios, or it
doesn't find lilo, or initramfs doesn't find root?
