Yup the problem is right here, and it's been around since 2014: https://github.com/openstack/nova/blob/16.0.0/nova/objects/block_device.py#L291
The regression that hits it is this: https://review.openstack.org/#/c/429476/ Before that, that code didn't lazy-load bdm.instance and hit that code. And it would only fail if you're running nova-api with debug logging enabled (which isn't uncommon really). Apparently we aren't hitting this in CI - probably because we don't gate on the NFS job. ** Tags added: api ** Changed in: nova Status: New => Triaged ** Changed in: nova Assignee: (unassigned) => Matt Riedemann (mriedem) ** Changed in: nova Importance: Undecided => High ** Also affects: nova/pike Importance: Undecided Status: New ** Changed in: nova/pike Status: New => Confirmed ** Changed in: nova/pike Importance: Undecided => High -- You received this bug notification because you are a member of Yahoo!
