I've managed to fix the installation so that the system will boot. Steps to fix: 1. Boot from LiveCD 2. switch over to console ( [Ctrl]+[Super]+[F1] ) and do ' lsmod | grep raid ' 3. mount the raid array to /mnt: 4. chroot /mnt 5. modify /etc/initramfs-tools/modules to include the modules listed in step 2 above. 6. rebuild initrd using mkinitramfs ( ' mkinitramfs -o /boot/initrd.img-3.13.0-24-generic 3.13.0-24-generic ' ) 7. reinstall grub ( ' update-grub && grub-install /dev/mapper/<mapper-name> ' ) 8. exit chroot 9. reboot 10. Profit!
List of modules displayed by the lsmod | grep raid : raid0 dm_raid raid1 raid10 raid456 async_raid6_recov async_memcpy async_pq async_tx raid6_pq it seems pretty silly that the above aren't included in the default image, as they're required to boot a RAID array. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1313169 Title: Ubuntu Trusty Tahr cannot boot on RAID5 array To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-lts-trusty/+bug/1313169/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
