only dynamically provisioned pvc can be resized and the storageclass that provisions the pvc must support resize
동적으로 프로비저닝된 pvc만 크기를 조정할 수 있고 pvc를 프로비저닝하는 스토리지 클래스가 크기조정을 지원해야 한다

# kubectl get sc standard
NAME                 PROVISIONER                RECLAIMPOLICY   VOLUMEBINDINGMODE   ALLOWVOLUMEEXPANSION   AGE
standard (default)   k8s.io/minikube-hostpath   Delete          Immediate           false                  28d

→ k8s.io/minikube-hostpath가 제공하는 standard 스토리지클래스는 볼륨확장을 지원하지 않는다.
