So there is no way to manually disable `need_online_data_migrations` behaviour. It is changed to `false` in /etc/ansible/facts.d/openstack_ansible.fact once `nova-manage db online_data_migrations` is completed successfully here:

https://opendev.org/openstack/openstack-ansible-os_nova/src/branch/master/tasks/nova_db_post_setup.yml#L47-L58

What is the reason why you look into that? Is "nova-manage db online_data_migrations" failing for you? As in this case you totally need to fix the reason for failure rather than look into how to skip them.

Hi,
I am not an openstack-ansible user but have used ansible for a while.
You are passing a variable(need_online_data_migrations) with a string('False') value.
So it is always true.

Pass a variable in a json format if it is a boolean variable.
Try -e '{"need_online_data_migrations": false}' in your ansible-playbook command.
