Subject: Re: [ceph-users] RBD rollback error mesage
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.
