I have had problems with a new installation of Ubuntu server 6.10 with the root partition on RAID1, and have identified two apparent errors:
1. In grub/menu.lst, the kernel parameter was root=/dev/hda1 instead of root=/dev/md0 2. In /etc/fstab, the UUID of the root partition is incorrect. Replaced the UUID with /dev/md0 and it worked. -- root raid installs have bad grub config https://launchpad.net/bugs/33649 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
