This step is... useless. Won't hurt anything, but doesn't achieve
anything.  It doesn't matter to grub which partition is or is not marked
bootable.. Unless you are doing something exotic by mixing MS-DOS chain
loader MTBR with grub, marking partitions as bootable has no effect.
You would need to setup grub on each device for grub to boot from either
hard drive.  However, since in this case, the /boot resides outside the
raid, you can't boot if the root drive is dead anyhow, so there is no
point in making the raid members bootable.
