Debian's installer - the mkinitrd part in particular - is broken. If you look in the "initrd" (it is just a compressed CPIO file) you will find the mdadm command used to start the root array explicitly lists the devices to use. As soon as you change the devices, it stops working :-( Someone should tell them about uuids. I think you can probably fix you situation by: Booting up and having a degraded array hot-add the missing device and wait for it to rebuilt rerun mkinitrd The last bit might require some learning on your part. I don't know in Debian's mkinitrd requires and command line args, or where it puts the result, or whether you have to tell lilo/grub about the new files. I would try just running "mkinitrd" with no args, and the "lilo" - if you are using lilo, and reboot. See what happens....
