What happen? 配置了nodemanager的pvc和storageclass之后没有生效 不管是手动创建好pvc或者配置storageclass，最终nodemanager的持久化目录都没用使用pvc

If existingClaim is configured, storageClass will not work.

感觉existingClaim这个参数无法起作用，client配置里，即使配置了已创建的pvc，实际容器起来后云盘还是没有挂载

I just checked the code, nodemanager doesn't support existingClaim.

WRT why it doesn't support storage class, still need investifation.

@zzc443701406 There is a switch in your cluster.yaml file:

persistence: false

Have you change this to true?
