I suspect this is related to the OSP10 having HostnameFormatDefault: '%stackname%-compute-%index%'( downstream only change - see BZ#1365789) while in OSP13 we have HostnameFormatDefault: '%stackname%-novacompute-%index%'

Description of problem: FFU: nova computes names change after updating stack outputs Version-Release number of selected component (if applicable): openstack-tripleo-heat-templates-8.0.2-0.20180327213843.f25e2d8.el7ost.noarch How reproducible: 100% Steps to Reproduce: 1. Deploy OSP10 with 3 controller + 2 computes + 3 ceph nodes and override the HostnameMap 2. Upgrade undercloud to OSP11/12/13 3. Run deploy command to update the stack outputs: source ~/stackrc export THT=/usr/share/openstack-tripleo-heat-templates/ openstack overcloud deploy --templates /usr/share/openstack-tripleo-heat-templates \ -e /usr/share/openstack-tripleo-heat-templates/environments/network-isolation.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/network-management.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/storage-environment.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/tls-endpoints-public-ip.yaml \ -e ~/openstack_deployment/environments/enable-cpu-pinning.yaml \ -e ~/openstack_deployment/environments/nodes.yaml \ -e ~/openstack_deployment/environments/network-environment.yaml \ -e ~/openstack_deployment/environments/disk-layout.yaml \ -e ~/openstack_deployment/environments/public_vip.yaml \ -e ~/openstack_deployment/environments/enable-tls.yaml \ -e ~/openstack_deployment/environments/inject-trust-anchor.yaml \ -e ~/openstack_deployment/environments/scheduler_hints_env.yaml \ -e ~/openstack_deployment/environments/ips-from-pool-all.yaml \ -e ~/openstack_deployment/environments/neutron-settings.yaml \ -e ~/openstack_deployment/environments/custom_hiera.yaml \ -e /home/stack/virt/docker-images.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/fast-forward-upgrade.yaml \ -e /home/stack/ffu_repos.yaml \ -e /usr/share/openstack-tripleo-heat-templates/environments/config-download-environment.yaml \ -e /home/stack/ceph-ansible-env.yaml \ Actual results: (undercloud) [stack@undercloud-0 ~]$ nova list +--------------------------------------+-------------------------+--------+------------+-------------+-----------------------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+-------------------------+--------+------------+-------------+-----------------------+ | 03191f87-4be8-49ba-9887-d8c9cd07a830 | cephosd-r00-00 | ACTIVE | - | Running | ctlplane=192.168.0.26 | | 81473264-5b08-4a7c-b539-c31598fe3776 | cephosd-r01-01 | ACTIVE | - | Running | ctlplane=192.168.0.18 | | a965be6b-9e74-42b7-af84-30af12d49c41 | cephosd-r02-02 | ACTIVE | - | Running | ctlplane=192.168.0.17 | | 83953a64-7058-4b1b-be25-39b198d39684 | controller-r00-00 | ACTIVE | - | Running | ctlplane=192.168.0.15 | | 6a8a4975-e9e3-433b-ad36-f1cf041dfae1 | controller-r01-01 | ACTIVE | - | Running | ctlplane=192.168.0.13 | | c2f03751-33bc-4c74-8d68-2d1146556df0 | controller-r02-02 | ACTIVE | - | Running | ctlplane=192.168.0.22 | | 283cfa7e-6b84-4a1f-8e5c-dd64102df15a | overcloud-novacompute-0 | ACTIVE | - | Running | ctlplane=192.168.0.11 | | 993f769d-d254-4e53-817a-b8e7c4e41079 | overcloud-novacompute-1 | ACTIVE | - | Running | ctlplane=192.168.0.14 | +--------------------------------------+-------------------------+--------+------------+-------------+-----------------------+ Expected results: (undercloud) [stack@undercloud-0 ~]$ nova list +--------------------------------------+-------------------+--------+------------+-------------+-----------------------+ | ID | Name | Status | Task State | Power State | Networks | +--------------------------------------+-------------------+--------+------------+-------------+-----------------------+ | 03191f87-4be8-49ba-9887-d8c9cd07a830 | cephosd-r00-00 | ACTIVE | - | Running | ctlplane=192.168.0.26 | | 81473264-5b08-4a7c-b539-c31598fe3776 | cephosd-r01-01 | ACTIVE | - | Running | ctlplane=192.168.0.18 | | a965be6b-9e74-42b7-af84-30af12d49c41 | cephosd-r02-02 | ACTIVE | - | Running | ctlplane=192.168.0.17 | | 283cfa7e-6b84-4a1f-8e5c-dd64102df15a | compute-r00-00 | ACTIVE | - | Running | ctlplane=192.168.0.11 | | 993f769d-d254-4e53-817a-b8e7c4e41079 | compute-r01-01 | ACTIVE | - | Running | ctlplane=192.168.0.14 | | 83953a64-7058-4b1b-be25-39b198d39684 | controller-r00-00 | ACTIVE | - | Running | ctlplane=192.168.0.15 | | 6a8a4975-e9e3-433b-ad36-f1cf041dfae1 | controller-r01-01 | ACTIVE | - | Running | ctlplane=192.168.0.13 | | c2f03751-33bc-4c74-8d68-2d1146556df0 | controller-r02-02 | ACTIVE | - | Running | ctlplane=192.168.0.22 | +--------------------------------------+-------------------+--------+------------+-------------+-----------------------+ Additional info: We can see that the compute node names got changed from compute-r00-00, compute-r01-01 to overcloud-novacompute-0, overcloud-novacompute-1 respectively which means that the HostnameMap configured during the initial deployment is no longer applied.
