That leaves only one case: when the file isn't thought to be in cloud, but is. For completeness

This correctly determines that the file is present, and updates the location log. But I don't understand why the message ``failed to download file from remote`` is used (which is also used when a file is present, and thought to be present). For a fast fsck it shouldn't be trying to download the file. Also, I don't think this is specific to S3, I expect any remote will have the same behaviour.
