I've been reading a bit and trying around but it seems I'm not quite where I want to be.
I want to migrate from pool "vms" to pool "vdisks".

Importing image: 100% complete...done.
# rbd snap ls vdisks/vm-102-disk-2
(no output)
# rbd export-diff --whole-object vms/vm-102-disk-2 - | rbd import-diff - vdisks/vm-102-disk-2
Exporting image: 100% complete...done.
Importing image diff: 100% complete...done.
# rbd snap ls vdisks/vm-102-disk-2
(still no output)
It looks like the current content is copied but not the snapshots.
What am I doing wrong? Any help is appreciated.
Hi Uwe,
If these are Proxmox images, would you be able to move them simply
using Proxmox Move Disk in hardware for VM? I have had good results
with that.
You are correct that this is on Proxmox but the UI prohobits moving Ceph-backed disks when the VM has snapshots.
I know how to alter the config files so I'm going the manual route here.
But thanks for the suggestion.

I'm still on luminous (12.2.8). I'll have a look on the commands. Thanks.

With the Mimic release, you can use "rbd deep-copy" to transfer the
images (and associated snapshots) to a new pool. Prior to that, you
could use "rbd export-diff" / "rbd import-diff" to manually transfer
an image and its associated snapshots.

Hi,
I have several VM images sitting in a Ceph pool which are snapshotted. Is there a way to move such images from one pool to another
and perserve the snapshots?
Regards,
Uwe
