grub2 install fails when /boot on raid1 device

[Adam]

Hi, I am having issues getting grub2 installed using a raid1 device for 
/boot:

# /usr/sbin/grub-probe --device-map="/boot/grub/device.map" --target=fs 
-v /boot/grub

I've tried removing /boot/grub/device.map and regenerating using 
"grub-install --recheck /dev/sda" but still issue persists.
