1. Prevent Pacemaker from triggering the Neutron cleanup scripts:

    pcs resource unmanage neutron-ovs-cleanup-clone
    pcs resource unmanage neutron-netns-cleanup-clone
   

2. Stop Neutron resources in Pacemaker:

    pcs resource disable neutron-server-clone
    pcs resource disable neutron-openvswitch-agent-clone
    pcs resource disable neutron-dhcp-agent-clone
    pcs resource disable neutron-l3-agent-clone
    pcs resource disable neutron-metadata-agent-clone
   

3. Upgrade the relevant packages:

    yum upgrade 'openstack-neutron*' 'python-neutron*'
   

4. Reload systemd to account for updated unit files:

    systemctl daemon-reload
   

5. Update the Neutron database schema

6. Update the Neutron rootwrap configuration

7. Restart Neutron resources in Pacemaker:

    pcs resource enable neutron-metadata-agent-clone
    pcs resource enable neutron-l3-agent-clone
    pcs resource enable neutron-dhcp-agent-clone
    pcs resource enable neutron-openvswitch-agent-clone
    pcs resource enable neutron-server-clone
   

8. Return the cleanup agents to Pacemaker control

    pcs resource manage neutron-ovs-cleanup-clone
    pcs resource manage neutron-netns-cleanup-clone
