== Presto machines to be upgrades [x] presto-worker-test 1 - `an-test-presto1001.eqiad.wmnet` [x] an-presto1001 [x] an-presto1002 [] an-presto1003 [] an-presto1004 [] an-presto1005 These machines should be relatively easy to upgrade, owing to the following factors. * There is no need for data retention - There is a `/srv/` volume mounted, but it does not contain any data of value. * We have already shown that presto on bullseye works with an-presto10[06-15] Therefore, the procedure to upgrade these hosts should be as simple as running the cookbook for each host as follows: ``` sudo cookbook sre.hosts.reimage --os bullseye -t 329361 an-presto1001 ``` We could also add one (or more) of the currently disabled presto hosts into the cluster to pick up the load of one worker being down. i.e. delete this file: https://phabricator.wikimedia.org/source/operations-puppet/browse/production/hieradata/hosts/an-presto1006.yaml
