I don't think it's a good idea.
Well, it could be a temporary workaround (_if_ it works) for btrfs until
it stabilizes.
But certainly not for md RAID-1. _If_ it did work for you, you would
have to take the whole array down as dd works, which is not good. md
provides its own tools (mdadm) to replace/rebuild the RAID.
