![增加 GKE 上的 PersistentVolumeClaim 的大小](https://linux22.com/image/725958/%E5%A2%9E%E5%8A%A0%20GKE%20%E4%B8%8A%E7%9A%84%20PersistentVolumeClaim%20%E7%9A%84%E5%A4%A7%E5%B0%8F.png)
我听说在 Kubernetes 的后续版本中(如果我没记错的话是 1.9 及以上版本;我有 1.10),只要allowVolumeExpansion: true
在 StorageClass 配置中设置,就可以扩展 PersistentVolume。
就我而言,在 GCP 上,我的 PVC 使用的 StorageClass 没有那行,而且我也无法添加它。
apiVersion: storage.k8s.io/v1
kind: StorageClass

storageclass.beta.kubernetes.io/is-default-class: "true"

因此,我想将 PV 及其对应的 PVC 从 8Gi 增加到 100Gi。最好的方法是什么?有没有办法在保留数据的同时做到这一点,还是必须先删除当前 PV 才能创建新的 PV?
这是 PV YAML:

遗憾的是,GKE 尚不支持此功能。您可以使用以下方式提交功能请求,以便在 GKE 的未来版本中启用此功能:公共问题追踪
