Tracking with this bug: https://bugs.launchpad.net/cinder/+bug/1520296 I suspect it was this change, or related to this change somehow: https://review.openstack.org/#/c/251421/ Since that's the only global ceph related change I can find in the last 24 hours. Otherwise it could be a regression in Tempest, but there was nothing obvious I could find there. The librados/librbd package versions in the test failure run were from September, so it doesn't appear to be a dependent package version update failure. -- Thanks, Matt Riedemann
