If you see the following similar issue when installing grub on a replacement drive

root@server:~# grub-install /dev/sdc
/usr/sbin/grub-probe: error: no such disk.
Auto-detection of a filesystem of /dev/md0 failed.
Please report this together with the output of "/usr/sbin/grub-probe --device-map=/boot/grub/device.map --target=fs -v /boot/grub" to 

Run the following

1. mv /boot/grub/device.map /boot/grub/device.map.old
2. grub-mkdevicemap
3. update-grub2
4. grub-install /dev/sdX (run for both drives)
