Then pull a disk (the right one) and see it stop booting. From
grub-install:
# Usage: getraid_mdadm mddevice
# Routine to find a physical device from an md device
# If found, the first grub BIOS device (from device.map) is returned
# If no BIOS drives match the RAID devices, the first device returned
# from mdadm -D is returned
Only one of your disks is bootable. By setting up each device in
device.map in turn you get grub on each of them.
