Presto machines to be upgrades
- presto-worker-test 1 - an-test-presto1001.eqiad.wmnet
- an-presto1001
- 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.
