Created attachment 1654441 [details] ansible.log Description of problem: Scale out deploy timings within the RDU scale lab of OSP16 are taking considerable longer than experiences with OSP13 (non config-download) Version-Release number of selected component (if applicable): OSP16 (RHOS_TRUNK-16.0-RHEL-8-20200113.n.0) How reproducible: 100% Steps to Reproduce: 1. Allocation of 300 baremetal nodes in scale env 2. Scale out env in increments of 50 3. defaults timeouts hit and deploy fails 4. bump up keystone token timeout Actual results: 1. Scale out of ~250 nodes with config download took 7.5hr (excludes stack create) Expected results: 1. Deploy timings equal or less than documented in the 500 BM node scale deploy with OSP13 Additional info: 1. Including ansible.log for deploy of the 250 node scale out 2 In osp13 the same scale out ( although no ceph which account for 1.5hr of the deploy) took ~2hrs
We have various new features coming in a future release of RHOSP 16 including `openstack overcloud deploy --limit` and a new Ansible strategy to help with the deployment time. *** This bug has been marked as a duplicate of bug 1767581 ***
