Observation¶

[15/11/2018 08:37:44] <fvogt> openQA is down: "result: setup failure: Cache service not available.". Just a usual Thursday?
[15/11/2018 08:38:15] <DimStar> already 4 hours ago - so a bit too early for a 'usual' thursday
…
[15/11/2018 09:14:22] <DimStar> okurz: who do I kick to fix o3/caching? :)
…
[15/11/2018 09:23:03] <okurz> what is the systemd service openqa-worker@multi-user?
[15/11/2018 09:28:14] <okurz> DimStar, sysrich: I suspect tonights upgrade of the o3 openQA workers broke it. I will try to find out the diff in the versions and see if I can revert something

Further investigation¶

I suspect https://github.com/os-autoinst/openQA/pull/1783 as it is related to "cache".

On openqaworker1 I started the systemd services openqa-worker-cacheservice-minion and openqa-worker-cacheservice manually and triggered a job https://openqa.opensuse.org/tests/796621#live which seems to run for now. I wonder if the services should be automatically started by package upgrades? But I guess not really because caching so far was just a "config option".

However I have the following observations:
