4. But the error is still here :
2021-01-15 09:33:58.775 7fa088e350c0 -1 librbd::DiffIterate: diff_object_map: failed to load object map rbd_object_map.781776950f8dd5.000000000000b740

You would need to rebuild the snapshot object map. First find the name
of the snapshot associated with snapshot id b740 (46912) via "rbd snap
ls <image-spec>", then run rebuild on that particule snapshot via "rbd
object-map rebuild <image-spec>@<snap name>".

Unfortunately it did not work : I can't succeed in finding the broken snaphot.

I have parsed all the snaphots of all the images in a loop, where I get all the SNAPIDs.

But none of these IDs is 46912 !

Please, can you tell me how did you get this number 46912 or a link which explain that ?

Many thanks,

Rafael
