I have a kubernetes cluster spread across two zones, A and B. I am using nfs volumes for persistent storage. I have nfs volumes in both the zones. I am creating a stateful set of 2 replicas which will be spread across these zones (I used pod anti-affinity to achieve this). Now I want the pods in zone A to use the volumes in zone A and ones in zone B to use the volumes in zone B.
I can add labels to the persistent volumes and match the persistent volume claims with these labels. But how do I make sure that the pvc for a pod does not get bound to a pv in another zone?
