Follow-up Comment #1, bug #64304 (project grub): At this point, if I 'sgdisk -Z /dev/sda', then OpenShift's GRUB no longer complains and boot proceeds normally without user interaction.
Can someone please see if GRUB can be repaired so that unknown data no longer tricks it into thinking it has many more disks than there actually are in the machine?
