Does this still occur if you export the images to the console (i.e. "rbd export cephstor/disk-116@snap - > dump_file")? Would it be possible for you to provide logs from the two "rbd export" runs on your smallest VM image? If so, please add the following to the "[client]" section of your ceph.conf: log file = /valid/path/to/logs/$name.$pid.log debug rbd = 20 I opened a ticket [1] where you can attach the logs (if they aren't too large).
