Cinder introduced extend capability a while back, so you can in fact create from source or snapshot a volume that's "larger" than the original. You just can't go the other way.
Extend is easy because you don't have to worry about eating somebody's file system etc. So in the case you describe, we do the create, copy the data and then do an extend.
