I don't like adding a whole separate CronJob manifest just to change this one parameter. Can we use a tpl function instead?

Actually events differs more, as they do not have hpa

Worth mentioning that we already have separate manifests for metrics and logs: https://github.com/SumoLogic/sumologic-kubernetes-collection/tree/main/deploy/helm/sumologic/templates/pvc-cleaner

I know, and I think 3 copies is enough to start making them DRY. It'd be best if we could have just one, with different parameters depending on config, but I'm not sure how realistic that is.

I can create issue for that. Right now I'm on customer support, so I would like to have it done rather quickly with low effort

If that happens, the Pod will fail to start in the new AZ, because the PVC name is the same, so the previous PVC would need to be manually deleted anyway.

This is what pvcCleaner is for. To remove this pvc, which cannot be attached to the pod

pvcCleaner was originally for cleaning up unused PVCs after metadata downscaling. It was definitely not for fixing AZ-related volume mounting problems. And it doesn't run frequently enough by default to be able to do this effectively anyway.

Actually I disagree, the original problem was AZ problem AFAIR, but it was result of non-cleaning unused PVCs. I think we can discuss it internally 😅
