Description Alexander Chuzhoy 2016-08-02 16:04:06 UTC

rhel-osp-director:   	Existing nodes get rebuilt during scale out after updating overcloud image post 9.0->9Async update

Environment:
openstack-puppet-modules-8.1.5-1.el7ost.noarch
instack-undercloud-4.0.0-8.el7ost.noarch
openstack-tripleo-heat-templates-liberty-2.0.0-18.el7ost.noarch
openstack-tripleo-heat-templates-kilo-2.0.0-18.el7ost.noarch
openstack-tripleo-heat-templates-2.0.0-18.el7ost.noarch


Steps to reproduce:
1. Deploy 9.0 with:
 openstack overcloud deploy --templates --control-scale 3 --compute-scale 1 --neutron-network-type vxlan --neutron-tunnel-types vxlan --ntp-server clock.redhat.com --timeout 90 -e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml -e network-environment.yaml --ceph-storage-scale 1
2. populate the overcloud
3. Update to 9.0Async
4. Update the overcloud images
5. Attempt to scale +1 compute

Result:
the scale fails. Looking on nova list and ironic node-list output shows that the existing nodes get rebuilt:
