I’m no longer using OpenHAB but if you have multiple Kubernetes nodes you’ll definitely want to use persistent volumes to manage the OpenHAB data. I think that the whole point of persistent volumes in Kubernetes is that Kubernetes ensures that the persistent volume is available on the node that is running your OpenHAB pod. If you created your own Kubernetes cluster from scratch it can be a bit of a challenge to get persistent volumes working properly as there are many things to get set up right but once it’s working it’s fairly auto-magical. If you’re having problems with persistent volumes though it’d probably be better to look for support on a Kubernetes-specific forum though.
