Public bug reported: Description ===========
When you use templates for cell creation and re-run create_cell command, duplicate cell will be created This happens because logic is broken here for templates: https://opendev.org/openstack/nova/src/commit/9e5feb051c15166988e87b10132927135bd56884/nova/cmd/manage.py#L623-L624 As cell.database_connection and cell.transport_url are already resolved into urls, while transport_url and database_connection are still templates. Steps to reproduce ================== Run 2 times: nova-manage cell_v2 create_cell --name cell1 --transport- url {scheme}://{username}:{password}@{hostname}//{path}?{query} --database_connection {scheme}://{username}:{password}@{hostname}/{path}?{query} --verbose This will result in creating 2 independent cells: root@aio1:~# /openstack/venvs/nova-22.0.0.0rc2.dev149/bin/nova-manage cell_v2 create_cell --name cell1 --transport-url {scheme}://{username}:{password}@{hostname}//{path}?{query} --database_connection {scheme}://{username}:{password}@{hostname}/{path}?{query} --verbose 046c88f0-097e-4a7c-9eee-45654355ff56 root@aio1:~# /openstack/venvs/nova-22.0.0.0rc2.dev149/bin/nova-manage cell_v2 create_cell --name cell1 --transport-url {scheme}://{username}:{password}@{hostname}//{path}?{query} --database_connection {scheme}://{username}:{password}@{hostname}/{path}?{query} --verbose b5f1672e-36c7-4d17-90b3-7433842cbbe0 root@aio1:~# /openstack/venvs/nova-22.0.0.0rc2.dev149/bin/nova-manage cell_v2 create_cell --name cell1 --transport-url {scheme}://{username}:{password}@{hostname}//{path}?{query} --database_connection {scheme}://{username}:{password}@{hostname}/{path}?{query} --verbose cf2efc1c-e091-4c93-96d4-84b3ecfa4647 root@aio1:~# Expected result =============== Following error should be raised along with command exit code 2: The specified transport_url and/or database_connection combination already exists for another cell with uuid ** Affects: nova Importance: Undecided Status: New -- You received this bug notification because you are a member of Yahoo!
