I do agree and suspect that it is a bug in grub-mkconfig. Why otherwise adding a new unformatted disk to the system should prevent grub from finding a root (and boot :) partition if it already been set in fstab? > Your initramfs tool may also do something here (I know dracut sticks a > copy of your fstab in the initramfs and uses it to help find the root > partition, assuming you have root in your fstab (if not it will > probably yell at you at some point)). > > You have to use an initramfs to use a UUID to mount your root. I do use initramfs (created by genkernel) as the system refuses to boot without it. I have already thought about it. Do you think that I should recreate initramfs anew after adding a new hard disk?
