Shouldn't be possible to move or copy (COW) big files between two subvolumes of one btrfs filesystem instantly - without real data movement? cp --reflink between subvolumes is returning error: cp: failed to clone `...': Invalid cross-device link mv between subvolumes is really slow - looks like it is moving all data To circumvent this I can create new snapshot and then remove everything except files I want to copy/move to this new subvolume and I gained the same effect quite fast, but indirectly, is there some way how to do it directly when subvolume already exists?
