The object, a Docker layer, that went missing has not been touched in
2 months. It worked for a while, but then suddenly went missing.
Was the object a
multipart object? You can check by running
radosgw-admin stat --bucket=BUCKETNAME --object=OBJECTNAME. It should
say something "ns": "multipart" in the output. If it says
"ns":
"shadow", it's a single-part object.
