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`. [1] https://lists.ceph.io/hyperkitty/list/ceph-users@ceph.io/thread/3CLRRBX25OGO... Zitat von Jan Kasprzak <kas@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
