Public bug reported: Hi,
When we delete a nova-compute service, the 'mapped' field in nova_cell1.compute_nodes table stays at 1 instead of 0 while nova_api.host_mappings related entry is completely removed. By letting that 'mapped' field to 1, it prevents nova-manage cell_v2 discover_hosts command to create the missing mapping. And that way, we can't anymore spawn on that compute because it's not linked to any cell. It may be linked to that bug: https://bugs.launchpad.net/nova/+bug/2077070 To fix, we can use the --by-service option: nova-manage cell_v2 discover_hosts --verbose --by-service like mentioned here: https://bugs.launchpad.net/nova/+bug/2077070/comments/7 A more global fix would be to set the 'mapped' field to 0 at nova- compute service deletion.
