I am new at this btrfs stuff!

As I understand it, you can add a physical disk or partition and have data spread into the new space.  You can also move data off a disk or partition and then remove it.

Has any though  been given to being able merge to existing (separate) btrfs "volumes" into a single volume?

Alternatively, how about at tool for transfering a subvolume from one pool to another?  I tried using fsarchiver but that did not work out too well.
