Kubernetes Persistent Volume：如果存储超过capactity会发生什么

Question

下面是我的PersistentVolume和PersistentVolumeClaim和config：

apiVersion: v1
kind: PersistentVolume
metadata:
  name: elasticsearch-pv
  labels:
    type: local
spec:
  capacity:
    storage: 10Gi
  accessModes:
    - ReadWriteMany
  hostPath:
    path: "/data/elasticsearch"


---

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
  name: elasticsearch-pvc
spec:
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 10Gi

容量和请求的资源仅为10Gb。但我的弹性搜索实例（其存储装载到elasticsearch-pvc）目前在主机上占用大约30Gb。这是hostPath PersistentVolume的预期行为吗？

Answer 1

是。这是resource request和limit之间的区别。
