[clug-talk] moving raid drives?

My guess would be that the initrd file doesn't contain the proper
modules for the disk controller in the new hardware. I've experienced
similar issues before. I would boot the system with a recovery CD.
Once the system is up, assemble the raid devices (md or lvm) and mount
the file systems to a location like /mnt/disk. Then chroot to /mnt/disk
and make sure important file systems like /boot, /proc, /sys etc are
there. If not run a mount -a. This should mount up the important
partitions from the /etc/fstab of the chrooted system.
Now you should be able to run mkinitrd which will build a new initrd for
the kernels in /boot based on the running module list from the rescue
kernel. I might take a backup of the /boot directory before just in case
(tar -czvf /usr/boot_backup.tgz /boot). If you're lucky the mkinitrd
will install the proper modules in your initrd, you should be able to
exit and reboot into your new system.
