Hi! I'll like to raise a question related to "How to clean Nova databases before running upgrades" We want to check that Nova databases (nova, nova_api, nova_cell0, nova_placement) are in good shape before running upgrade, we know that there is some effort to "purge the deleted instances" but no patches yet for that.
In general, how can I know we have cleaned all Nova DBs? This can be i.e. for maintenance purposes or for checking it before the major upgrade. Currently the command we run is: nova-manage db archive_deleted_rows --max_rows 100 --until-complete Still, the archived rows are stored in shadow tables so we still have a big DB, and there is some specs[1] to remove them but nothing landed/usable.
