I was able to solve my problem by reinstalling grub2 to the raid device. Booting from a live cd in 10.10 shows the device partition as ...ARRAY01, while under 11.04 the same partition is ARRAY0p1.
Also, /etc/default/grub was missing after the upgrade, and it seemed an old grub was installed. This information was important when following the chroot instructions here: http://ubuntuforums.org/showthread.php?t=1581099 After reinstalling grub 2 I was able to boot, and clean up the incorrect entries for the root and swap partitions in /etc/fstab. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/745960 Title: Cannot boot grub after installing to LVM To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-release-notes/+bug/745960/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
