I installed ubuntu server 10.04 on a PC with two HD drives 500 GB each. I used raid1 to provide data protection. The /boot partition is installed also on a mirrored device /dev/md0.

After the installation has completed, the system did not boot properly. I got the following error message:

ALERT! /dev/disk/by-uuid/<long characters> does not exist. Dropping to a shell!

Any idea what could cause such a problem?

UPDATE:

I booted into rescue mode using the installation CD. Executing fdisk showed me the partitions, but it said "Partition 1 does not end on cylinder boundary.". Can this be related to the problem at hand?

UPDATE2:

I re-installed ubuntu server without the Raid at all. The system booted as it should be! Also, I got the same error from fdisk after booting. So, this error should not be related to this problem of not being able to boot.

It is puzzling me. Can't I install ubuntu server 10.04 with raid1?!!

Probably either the initramfs didn't include a raid hook.Assuming it happens after the grub menu.But why don't you use btrfs built-in raid1?

I think Grub doesnt support btrfs now –  Extender Nov 15 '10 at 9:26
