Here's some info about the image (not sure if it's relevant): ---snip--- ceph1:~ # rbd info rbd-pool1/cloud7 rbd image 'cloud7': size 1.4 GiB in 347 objects order 22 (4 MiB objects) snapshot_count: 0 id: 149e4eb8e387a block_name_prefix: rbd_data.149e4eb8e387a format: 2 features: layering, exclusive-lock, object-map, fast-diff, deep-flatten, journaling op_features: flags: create_timestamp: Thu Sep 10 11:59:18 2020 access_timestamp: Thu Sep 10 11:59:18 2020 modify_timestamp: Thu Sep 10 12:03:30 2020 journal: 149e4eb8e387a mirroring state: enabled mirroring mode: journal mirroring global id: 82bb30ec-bd33-4f84-9d0c-b3650b567670 mirroring primary: true ---snip--- Is this worth a bug report or is it already known and I just couldn't find anything?
