Hi,
Mykola explained it in this thread [1] a couple of months ago:
`rbd cp` will copy only one image snapshot (or the image head) to the
destination.
`rbd deep cp` will copy all image snapshots and the image head.
It depends on the number of snapshots that need to be copied, if there
are none you'd probably be fine with `rbd cp`.

Zitat von Jan Kasprzak <k...@fi.muni.cz>:
Hello, Ceph users,
what is the difference between "rbd cp" and "rbd deep cp"?
What I need to do is to make a copy of the rbd volume one of our users
inadveredly resized to a too big size, shrink the copied image to the
expected size, verify that everything is OK, and then delete the original
image. Would this work with rbd cp?
Thanks,
-Yenya
