Hi, I have just finished an installation of archlinux onto a btrfs
partition (although it is not a multi-device btrfs partition) with /boot
in a separated subvolume. For my case the grub2 works well. Before your
running of grub-install, have you checked if /root is accessible from
your chroot environment?
