OK, chapter 2. - Boot from rescue CD. - After it asks for keyboard layout and network, but before it scans for Linux partitions, Ctrl-Alt-F2 and do # mdadm -AR /dev/md0 /dev/hdb /dev/hdc. It runs /dev/md0. - Switch back to rescue installer, and have it scan for Linux partitions. It finds the install! - I can now chroot /mnt/sysimage and build my own initrd. It builds in the RAID drivers, and device mapper! - Reboot with the new initrd. It loads the RAID module, and seems to correctly detect /dev/md0, but it still does NOT find the volume group!!! Same output: Couldn't find device with uuid ... Couldn't find all physical volumes for volume group VolGroup00 I tried again and generated an initrd with --noresume, but that doesn't change things at all. Argh! Maybe I can separate the VGs so that the RAID array isn't part of VolGroup00.
