I feel you may have some misunderstanding about how Btrfs is supposed to work in this aspect and what it was doing in your setup. E.g. if you added a new drive and then rebalanced metadata to RAID1 profile, that still means Btrfs was going to use the new drive for new allocations of data extents too, not just metadata. -- With respect, Roman
