Repeated "Placement API returning an error response: Inventory for '...' in use." appears in nova-placement-api.log. It was easily confused as possible issue for ospd deployment timing out on provisioning. Already known as https://bugs.launchpad.net/nova/+bug/1751472, backport needed. Expected would be to not have log full of 'placement api returning error response' (>500 occurencies with 3 node setup). > 2018-04-16 15:04:41.546 13822 INFO nova.api.openstack.placement.requestlog [req-f7b36ab7-994b-40dc-8700-2ba466168656 053d187961d14e0db78b7b3c4bca29e3 a4df037075734a8f84fea4228bccefaf - default default] 192.168.24.1 "GET /placement/resource_providers/7af6c15b-12c7-4502-bcca-264a5bdf2d6d/inventories" status: 200 len: 512 microversion: 1.0 > 2018-04-16 15:04:41.551 13821 DEBUG nova.api.openstack.placement.requestlog [req-32745f6a-fd9a-4598-bbc0-0fb90070177b 053d187961d14e0db78b7b3c4bca29e3 a4df037075734a8f84fea4228bccefaf - default default] Starting request: 192.168.24.1 "DELETE /placement/resource_providers/7af6c15b-12c7-4502-bcca-264a5bdf2d6d/inventories" __call__ /usr/lib/python2.7/site-packages/nova/api/openstack/placement/requestlog.py:38 > 2018-04-16 15:04:41.559 13821 DEBUG nova.api.openstack.placement.wsgi_wrapper [req-32745f6a-fd9a-4598-bbc0-0fb90070177b 053d187961d14e0db78b7b3c4bca29e3 a4df037075734a8f84fea4228bccefaf - default default] Placement API returning an error response: Inventory for 'VCPU, MEMORY_MB, DISK_GB' on resource provider '7af6c15b-12c7-4502-bcca-264a5bdf2d6d' in use. call_func /usr/lib/python2.7/site-packages/nova/api/openstack/placement/wsgi_wrapper.py:31
