Using Ansible to upgrade to Openstack Kilo commands do not respond

Issue

• We are upgrading to kilo following Redhat official document, as part of that we have run command to upgrade the nodes using below command.

#sed -i 's/keystone.token.backends/keystone.token.persistence.backends/g' /etc/keystone/keystone.conf
# openstack-db --service cinder --update
# openstack-db --service glance --update
# openstack-db --service heat --update
# openstack-db --service keystone --update
# openstack-db --service neutron --update
# openstack-db --service nova --update
# systemctl start rabbitmq-server

• But when we run the ansible(below command) the system does nothing, no outpur/error is given.

ansible compute -a "runuser -u nova -- nova-manage db migrate_flavor_data" -f 100 

• Can I skip this command and continue with the next?
• These are the two command in line next.

# ansible openstack -a "openstack-service start" -f 100
# sed -i 's:#16:16:' /var/spool/cron/root        ===============> to avoid using ansible playbooks
