I had an old server die; we had another, same model, sitting around lightly used, so I did what I've done before: swap the RAID card into that, swap the drives, even putting them in the same bays as the dead one, and boot.
Nope. 100% of the time, when it hits switching roots, it kernel panics.
Adding rdshell to the kernel line does nothing, I get no grub rdshell. Booting from a flash drive into rescue, it finds everything, *perfectly*, and mounts it all, including the RAID data drives.
I've rebuilt the initrd, and no joy.
Anyone have an idea?
Did you try running "grub-install" after your rescue-mode boot and chroot into /mnt/sysimage? If that doesn't fix it there is probably something different about the device/naming of the root partition.
