Feel VERY free to chime in on this discussion > https://github.com/longhorn/longhorn/discussions/5593 < 😄 thank you!

some combo of having new worker nodes already online with the new value set, volume cloning https://kubernetes.io/docs/concepts/storage/volume-pvc-datasource/ and all of the manual edits ready to go as kubectl apply -f yaml file writes?

Uh yeah. Like the idea. The issue is that for new workers to get the new location of the kubelet. The longhorn workloads I mention in the discussion that I’ve lined to, needs to be updated. When that’s done those are recreated and now the old volumes are no longer able to properly umount the volumes.
