I come to the same error when I try to install a system with debootstrap. After debootstrap I mount /proc, /dev and /sys and chroot in the system (like there https://wiki.ubuntu.com/Grub2#Recover%20Grub%202%20via%20LiveCD).
than: r...@rescue:/# grub-install --recheck --no-floppy --modules="mdraid raid" /dev/sda1 /usr/sbin/grub-probe: error: no mapping exists for `md1'. /usr/sbin/grub-probe: error: no mapping exists for `md1'. /usr/sbin/grub-probe: error: no mapping exists for `md1'. You attempted a cross-disk install, but the filesystem containing /boot/grub does not support UUIDs.
