I have just upgraded an Ubuntu desktop 8.10 to 10.04
The drive configuration is a single drive with the O/S, and two pairs of disks on software RAID1.
When I reboot the server, I get error messages on startup telling me that /dev/md0 and /dev/md1 are inaccessible; I have to skip mounting them in order to proceed. However, if I use Syetem -> Administration -> Disk Utility once I have logged in, I can see the drives and if I tear down the two RAID devices and bring them back up again they both come back healthy.
The problem only seems to be bringing them online on startup. Any suggestions?

I had the same. Worked around it by booting with kernel 2.6.32-24-generic instead of 2.6.32-24-generic-pae.

Thanks for the suggestion but it didn't work for me; I didn't have a pae kernel anyway.
I did solve it, though: apt-get remove mdadm mv /etc/mdadm/mdadm.conf /etc/mdadm/mdadm.conf.old apt-get install mdadm
It looks like the key problem was mdadm.conf, although I didn't investigate any further.
