There was a bug in "rbd import" where it disallowed the use of stdin for export-format 2. This has been fixed in v12.2.9 and is in the pending 13.2.3 release.

Re: [ceph-users] Move rdb based image from one pool to another
If your CLI supports "--export-format 2", you can just do "rbd export --export-format 2 vms/vm-102-disk2 - | rbd import --export-format 2 - vdisks/vm-102-disk-2" (you need to specify the data format on import otherwise it will assume it's copying a raw image).

Re: [ceph-users] Move rdb based image from one pool to another
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". # ceph osd pool ls vms vdisks # rbd ls vms vm-101-disk-1 vm-101-disk-2 vm-102-disk-1 vm-102-disk-2 # rbd snap ls vms/vm-102-disk-2 SNAPID NAME SIZE TIMESTAMP 81 SL6_81 100GiB Thu Aug 23 11:57:05 2018 92 SL6_82 100GiB Fri Oct 12 13:27:53 2018 # rbd export --export-format 2 vms/vm-102-disk-2 - | rbd import - vdisks/vm-102-disk-2 Exporting image: 100% complete...done. 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. Thanks, Uwe Am 07.11.18 um 14:39 schrieb Uwe Sauter: I'm still on luminous (12.2.8). I'll have a look on the commands. Thanks.

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

Re: [ceph-users] Move rdb based image from one pool to another
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.
