commit 589c495c1ae62129e20ab5e2641e330541eee01f Author: Surya Seetharaman <[email protected]> Date: Wed Mar 21 14:16:24 2018 +0100 Cleanup RP and HM records while deleting a compute service. Currently when deleting a nova-compute service via the API, we will (soft) delete the service and compute_node records in the DB, but the placement resource provider and host mapping records will be orphaned. This patch deletes the resource provider and host_mapping records before deleting the service/compute node. Change-Id: I7b8622b178d5043ed1556d7bdceaf60f47e5ac80 Closes-Bug: #1756179 ** Changed in: nova Status: In Progress => Fix Released -- You received this bug notification because you are a member of Yahoo!

The orphaned resource provider records have been found to cause scheduler failures if you re-create the compute node with the same name (but a different UUID). It has been theorized that the stale host mapping records could end up pointing at the wrong cell. In discussions on IRC (http://eavesdrop.openstack.org/irclogs /%23openstack-nova/%23openstack- nova.2018-03-15.log.html#t2018-03-15T19:30:13) it was proposed that we should 1. delete the RP in placement 2. delete the host mapping 3. delete the service/node Optionally we could delete the compute node prior to deleting the service to make it explicit and because the ordering is slightly more logical, but this is not a requirement since it will be done implicitly as part of deleting the service.
