Again I ran into this. System was an Ubuntu 8.10 with an 8-disk md array plus separate system disk. Given that 8.10 is not supported anymore, I needed to upgrade to 10.04. All I did was change sources.list to lucid and apt-get dist-upgrade, reboot, and I am left without my array.
* mdadm.conf is the default, no ARRAY line
* mdadm --auto-detect does nothing
* mdadm --assemble /dem/md0 complains
Worse,
* Adding ARRAY /dev/md0 devices=/dev/sda,/dev/sdb,/dev/sdc,/dev/sdd,/dev/sde,/dev/sdf,/dev/sdg,/dev/sdh to mdadm.conf and doing mdadm --assemble /dem/md0 says that /dev/sdb has no superblock - which is freaky, given that it worked fine before the upgrade.

So, this is still breaking systems, even when upgrading to the latest 10.04 LTS.
