I am trying to follow this tutorial to create a Galera cluster using kubernetes on AWS, but I see that the Dynamic provisioning of the volume fails and this is the error I see in kube-controller-manager.log

0711 06:12:21.065942       6 aws_ebs.go:434] Provision failed: claim.Spec.Selector is not supported for dynamic provisioning on AWS

I am not sure what is wrong, it is using a default storage class of type 'gp2'. Any suggestions on this ?
