Hi Tony, Yes, at a high level it should be the same. > Also, seems cp is a bit faster and flatten, is that true? I can't think of anything that would make "rbd cp" faster. I would actually expect it to be slower since "rbd cp" also attempts to sparsify the destination image (see --sparse-size option), making it more space efficient.
