Which is fine for some occasions and a very good start point. However, I'm sure there is a strong wish to be able to specify n-copies of data/metadata spread across m devices. Or even to specify 'hot spares'. This would be a great to overcome the problem of a set of drives becoming "read-only" when one btrfs drive fails or is removed. (Or should we always mount with the "degraded" option?)
