Bug Description
grub2 LVM support handles MD raid 4.5 and 6 but not raid1. If you make your boot or root raid1 it is no longer able to even list the volumes. It is therefore possible to boot your system, add a mirror, reboot and have no system at all. I would guess raid1 would be a degenerate case of the mirror support that already exists.
