The release notes (https://docs.openstack.org/releasenotes/designate/) for the change between V and W are essentially empty, so this should be an easy one.
- prepare a patch that upgrades the openstack version /only/ on cloudservices (via profile::openstack::<deployent>::version settings in puppet/hieradata/hosts/<hostnames>)
https://gerrit.wikimedia.org/r/c/operations/puppet/+/774523
- disable puppet on cloudservices nodes from cumin1001.eqiad.wmnet
$ sudo cumin 'cloudservices100*' "disable-puppet 'Upgrading to openstack Wallaby - T304880 - ${USER}'"
- merge above patch
One node at a time:
- cloudservices1003.wikimedia.org
- cloudservices1004.wikimedia.org
- puppet agent --enable && puppet agent -tv
- apt-get update
- DEBIAN_FRONTEND=noninteractive apt-get install python3-designate designate-sink designate-central designate-worker designate-mdns designate-api -o "Dpkg::Options::=--force-confdef" -o "Dpkg::Options::=--force-confold"
- DEBIAN_FRONTEND=noninteractive apt-get upgrade -o "Dpkg::Options::=--force-confdef" -o "Dpkg::Options::=--force-confold"
- puppet agent -tv
- designate-manage database sync
- puppet agent -tv
- reboot host
- systemctl list-units --failed (should show nothing failed)
Test by digging @ both the pdns-recursor ip and the pdns auth ip, a couple of randomly-chosen VM fqdns.
