Can you run "rbd info" against that image? I suspect it is a harmless but alarming error message. I actually just opened a tracker ticket this morning for a similar issue for rbd-mirror [1] when it bootstraps an image to a peer cluster. In that case, it was a harmless error message that we will correct.
