commit f4f17b364e28389f22bf9c6017dd7aef918c7104 Author: Takashi NATSUME <[email protected]> Date: Sun Oct 8 00:55:50 2017 +0900 Add 'delete_host' command in 'nova-manage cell_v2' Add 'delete_host' command in 'nova-manage cell_v2'. Add an optional 'force' option in 'nova-manage cell_v2 delete_cell'. If specifying the 'force' option, a cell can be deleted even if the cell has hosts.

Steps to reproduce ================== In cell v2 environment, a cell to delete has only one compute host. 1. Delete the nova-compute service > nova service-delete db8e01f5-021d-4c87-a4eb-f3e5089e6105 The records are soft deleted in the 'services' table and the 'compute_nodes' table of the cell database. But the record in 'host_mappings' table of api database is not deleted. 2. Delete the cell > nova-manage cell_v2 delete_cell --cell_uuid 0fcd92ba-b257-4fbc-94d5-9ac6a77ccf81 There are existing hosts mapped to cell with uuid 0fcd92ba-b257-4fbc-94d5-9ac6a77ccf81. The command fails with the message above. It is caused because the host record remains in the 'host_mappings' table of api database. But there is no ways to delete the host record in the 'host_mappings' table. Expected result =============== The cell can be deleted if the cell does not have any hosts. Or we should have the way to delete the host from the cell. Actual result ============= The cell cannot be deleted even though the cell does not have any hosts. (We don't have the way to delete the host from the cell.)
