Engineering Team, which is subscribed to OpenStack Compute (nova). https://bugs.launchpad.net/bugs/1750618 Title: rebuild to same host with a different image results in erroneously doing a Claim Status in OpenStack Compute (nova): Triaged Status in OpenStack Compute (nova) ocata series: Triaged Status in OpenStack Compute (nova) pike series: Triaged Status in OpenStack Compute (nova) queens series: Triaged Bug description: As of stable/pike if we do a rebuild-to-same-node with a new image, it results in ComputeManager.rebuild_instance() being called with "scheduled_node=<hostname>" and "recreate=False". This results in a new Claim, which seems wrong since we're not changing the flavor and that claim could fail if the compute node is already full. The comments in ComputeManager.rebuild_instance() make it appear that it expects both "recreate" and "scheduled_node" to be None for the rebuild-to-same-host case otherwise it will do a Claim. However, if we rebuild to a different image it ends up going through the scheduler which means that "scheduled_node" is not None.
