I am continuing to set up my home server on FreeBSD 14.3, which is intended to serve as a NAS. In the previous post, FreeBSD: introduction to Packet Filter (PF) firewall, we got acquainted with firewalls; the next step is to configure a VPN for access.

We have a VictoriaLogs Helm chart with a PVC size of 30 GB, which is no longer enough for us, and we need to increase it. But the problem is that .spec.volumeClaimTemplates[*].spec.resources.requests.storage in STS is immutable, that is, we can’t just change the size through values.yaml file, because it will lead to the error“Forbidden: updates… Read More »
It’s not the first time I’ve encountered similar errors when upgrading VictoriaMetrics, so it’s time to note a solution.
