Ubuntu Server 12.10 boot problem
I performed a fresh install of Ubuntu Server 12.10 x64 on a 64GB SSD. This entire drive is for o/s use. I have a RAID-5 volume from my old Ubuntu Server 12.10 x64 server build that I want to move into this new build. It's an Ubuntu soft-RAID. From what I've read, it should be portable so long as mdadm is installed on the new system, which it is. Unfortunately, when I add the disks to the system it boots to an initramfs prompt. Take the RAID volume out and it boots up fine. I tried re-installing the o/s with the RAID drives present, and the installer recognizes the volume and installs a couple RAID packages so that I see the volume when I come to the screen to set up partitioning. Seems like GRUB loader doesn't find the boot volume during boot-up, but I have no idea how to address or fix that. Of course that's just an idea and may not be the issue at all.
Any suggestions would be greatly appreciated. I have a good backup of the data, but I'd like to get through this without rebuilding the volume, if for anything else, to learn what the problem is and how to resolve it.
