Hi Jason,
now I'm a bit confused ...
I recreated the peers again with names clear:
#main site:
rbd mirror pool info testpool
Mode: image
Site Name: master
Peer Sites:
UUID: e7443ebd-b9e2-47ab-bcfe-f40cb75a6294
Name: backup
Mirror UUID: e0d03424-1913-4e0b-90dd-61defabae51a
Direction: tx-only
#backup site:
rbd --cluster backup mirror pool info testpool
Mode: image
Site Name: backup
Peer Sites:
UUID: a7ffac0b-09e3-427c-a3a1-5f001a55dcf1
Name: master
Mirror UUID:
Direction: rx-tx
Client: client.admin
In my opinion this looks ok, but the error seems the same:
2020-07-24T21:14:21.559+0200 7fb9d709a700 -1
rbd::mirror::image_replayer::snapshot::Replayer: 0x56122bb43800 init: failed to retrieve

If I disable mirroring on the testimage on main site, the mirror daemon tells me:
2020-07-24T21:15:58.775+0200 7f3cd6f3b700 -1

handle_unregister_local_update_watcher: failed to unregister local update watcher: (2) No

The created image on the backup site doesn't get removed.
Journal based mirroring works without any problem on the same image.
Thanks for any hints
Yves

You need to have unique names for your site -- so "ceph" is not an appropriate
name. Right now, your backup set is named "ceph" and you have a peer named
"ceph".
