Here you go: rbd image 'aircds': size 8192 MB in 2048 objects order 22 (4096 kB objects) block_name_prefix: rbd_data.39202eb141f2 format: 2 features: layering, exclusive-lock, object-map, fast-diff, deep-flatten flags: parent: rbd/xenial-base@gold-copy overlap: 8192 MB Brendan ________________________________________ From: Jason Dillaman [jdillama@xxxxxxxxxx] Sent: Tuesday, June 07, 2016 6:56 PM To: Brendan Moloney Cc: ceph-users@xxxxxxxxxxxxxx Subject: Re: 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.
