Hi all, we have started facing node volume affinity issue in our pinot pods after we did an AMI version update to our EKS node groups on which our Pinot is hosted. We had only a single pod(for controller and zookeeper) and since PVCs are AZ bound and the EKS on AMI update changed the AZ in which the node is present we faced this issue. We are planning on having one nodegroup per every AZ(total 3) we have. 3 node groups of controller and zookeeper. Are there any best practices we can follow to avoid this?

if you want to adopt the AZ aware setup, this is a recommended one .

okay thanks!
