Chapter 7. Executing Post Upgrade Steps

This process implements final steps after completing the main upgrade process.

Prerequisites

  • You have completed the overcloud upgrade to the latest major release.

The following items are general considerations after an overcloud upgrade:

  • If necessary, review the resulting configuration files on the overcloud nodes. The upgraded packages might have installed .rpmnew files appropriate to the upgraded version of each service.

  • The Compute nodes might report a failure with neutron-openvswitch-agent. If this occurs, log into each Compute node and restart the service. For example: 

    $ sudo docker restart neutron_ovs_agent

  • In some circumstances, the corosync service might fail to start on IPv6 environments after rebooting Controller nodes. This is due to Corosync starting before the Controller node configures the static IPv6 addresses. In these situations, restart Corosync manually on the Controller nodes: 

    $ sudo systemctl restart corosync
