Another note: When I install Dapper into the RAID1 configuration from scratch, it works (as noted above). If I then upgrade from Dapper to Edgy via the Upgrade Manager, the system continues to work -- that is, grub boots the system fine with /boot on RAID1 device and menu.lst references /dev/md1 and finds it.
It's just when installing Edgy from scratch that grub can't seem to find what it's looking for after the reboot. -- Cannot boot to RAID1 /boot after successful Edgy install https://launchpad.net/bugs/70551 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
