Persistent volumes between worker nodes

Summary

Looking into how to share PVCs between worker nodes in different ADs

Content

Hi,

Use case: a POD that only has 1 replica, but with a PVC attached. In this particular case the nodepool has 2 worker nodes, 1 in each AD.

In the yaml for the PVC you have to state the AD you want the storage to be created in.

Now I am wondering: if somehow the POD gets moved from the worker node on AD1 to the worker node on AD2, is all the data contained on the PVC following to the other AD?

On GKE (Google) you can provision something like a 'regional' persistence volume, over different zones. Anything like this available on OKE?
