The easy fix here is to change:

GRUB_CMDLINE_LINUX="rootflags=subvol=${rootsubvol} ${GRUB_CMDLINE_LINUX}"

to:

GRUB_CMDLINE_LINUX="rootflags=subvol=${rootsubvol},degraded ${GRUB_CMDLINE_LINUX}"

in /etc/grub.d/10_linux.

Any time your root filesystem is on btrfs, attempting to boot in a degraded state is the best choice to help recovery. You can't rebuild your btrfs raid without swapping disks and running a balance.
