Public bug reported: I found this in the starlingx diff for nova:
https://github.com/starlingx-staging/stx- nova/commit/71acfeae0d1c59fdc77704527d763bd85a276f9a#diff- afb9c0c0ca5276c7eacd987bbf51d8e6R447 For volume-backed instances, the instance image_meta comes from the volume_image_metadata in the volume for the root bdm, the API figures that out here: https://github.com/openstack/nova/blob/4c37ff72e5446c835a48d569dd5a1416fcd36c71/nova/compute/api.py#L1099 https://github.com/openstack/nova/blob/4c37ff72e5446c835a48d569dd5a1416fcd36c71/nova/compute/api.py#L1568 Then during an evacuate of a volume-backed instance, the rebuild_claim in the ResourceTracker won't actually get the proper image_meta because of this code in ComputeManager.rebuild_instance: https://github.com/openstack/nova/blob/4c37ff72e5446c835a48d569dd5a1416fcd36c71/nova/compute/manager.py#L2985 The only thing in the claims code that cares about image_meta is for calculating numa_topology claims: https://github.com/openstack/nova/blob/4c37ff72e5446c835a48d569dd5a1416fcd36c71/nova/compute/claims.py#L295 I'm not even totally sure if evacuate fully works with an instance using numa topology, but this can't help. ** Affects: nova Importance: Medium Status: Triaged ** Tags: evacuate numa volumes -- You received this bug notification because you are a member of Yahoo!
