I don't understand why anyone would run btrfs with MD RAID. That configuration loses the ability to recover from corrupted blocks. All that MD can do is in response to actual reported drive errors. If one of the drives accepts the write but then later silently returns the old data, which is a failure mode I have actually seen, MD can't do anything reasonable to fix it.
