3장. Performing pre-upgrade actions

Procedure

1. Check the status of the OVN cluster resources and fix any issues:

   $ sudo pcs status

   참고

   If you need help resolving any issues, contact Red Hat Support before you proceed with the upgrade.

2. Check in the Failed Resource Actions section of the output of the OVN cluster resources status for the following error:

   Failed Resource Actions:
     * ovndb_servers_monitor_30000 on ovn-dbs-bundle-1 'not running' (7): call=24, status='complete', exitreason='', last-rc-change='2025-08-08 09:21:30Z', queued=0ms, exec=159ms

3. If you see the error, check the status of the ovndb_servers resource on controller-0:

   $ sudo podman exec <ovn-dbs container> ovs-appctl -t /var/run/openvswitch/ovnnb_db.ctl ovsdb-server/sync-status

   • Replace <ovn-dbs container> with the name of the ovn-dbs container that you want to check.

4. If the output includes a reference to the IP address, 192.0.2.254, instead of the virtual IP address, you must restart the ovn-dbs-bundle on the overcloud Controller node:

   $ sudo pcs resource restart ovn-dbs-bundle

   192.0.2.254 is a fallback IP address. Its presence in the output indicates that there is an issue.
