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 in chrooted env.
I think it doesn't find the root partition.
Screenshot from the boot screen: http://kiru.mikroweb.hu/IMGP6301-s.JPG (with debug=y kernel arg.)
I did this with an ubuntu live cd.
My system looks like:
