Hi, I created a rbd group to snap multiple images consistent regarding point in time: # rbd group image ls vm1010 rbd/5c6acb6f-a6ea-49f4-b709-ca10d423ad42.rbd.disk1 rbd/770e7d64-128a-4e85-9906-b49332b0df26.rbd.disk0 # rbd group snap ls vm1010 ID NAME STATE 4c8d35cc0d0177 snap-1 complete But how do I export/export diff a group snap? The individual images show no snaps: # rbd group snap info vm1010@snap-1 rbd group snapshot 'snap-1': id: 4c8d35cc0d0177 state: complete image snap: .group.1_18efdc6b8b4567_4c8d35cc0d0177 images: rbd/5c6acb6f-a6ea-49f4-b709-ca10d423ad42.rbd.disk1 (snap id: 202) rbd/770e7d64-128a-4e85-9906-b49332b0df26.rbd.disk0 (snap id: 203) # rbd info rbd/5c6acb6f-a6ea-49f4-b709-ca10d423ad42.rbd.disk1 rbd image '5c6acb6f-a6ea-49f4-b709-ca10d423ad42.rbd.disk1': size 22 GiB in 5632 objects order 22 (4 MiB objects) snapshot_count: 1 id: 18efd69508379e block_name_prefix: rbd_data.18efd69508379e format: 2 features: layering, exclusive-lock, object-map, fast-diff, deep-flatten, operations op_features: group flags: group: rbd/vm1010 create_timestamp: Tue Nov 15 12:59:56 2022 access_timestamp: Thu Mar 5 13:59:29 2026 modify_timestamp: Thu Mar 5 14:00:06 2026 # rbd snap ls rbd/5c6acb6f-a6ea-49f4-b709-ca10d423ad42.rbd.disk1 <no output> Ceph version is v20.2.0 with cephadm.
