director nova-api does not respond to metadata requests causing a scaleout to timeout and fail in RHOSP

Solution In Progress - Updated -

Issue

  • Director nova-api does not respond to metadata requests causing a scaleout to timeout and fail.
  • Openstack scale out fails due to metadata server unreachability in RHOSP even when nova-api are up and running.
  • below logs are found in controller node :
Sep 07 16:45:44 hostname.example.com os-collect-config[5094]: HTTPConnectionPool(host='169.254.169.254', port=80): Read timed out. (read...=10.0)
  • We see following in newly added compute node after logging in (scale out process timed out)
