How to define the name of the PV on the NFS directory after dynamically creating PV using PVC

[caijinhu123]

pvc.yaml
apiVersion: v1 kind: PersistentVolumeClaim metadata: name: pvc-nfs-dynamic spec: accessModes: - ReadWriteMany resources: requests: storage: 10Gi storageClassName: nfs-csi
After creating PVC using the above YAML, the name of the PV on the NFS directory is
pvc-5a900a0e-506b-470f-b1de-03a021fb44b6

When defining the storage class, add the 'subDir' parameter, just like the example below

apiVersion: storage.k8s.io/v1
kind: StorageClass
metadata:
  name: nfs-csi
provisioner: nfs.csi.k8s.io
parameters:
...
  subDir: ${pvc.metadata.namespace}-${pvc.metadata.name}-${pv.metadata.name}
reclaimPolicy: Delete
volumeBindingMode: Immediate

After modifying the storage class, redeployment is required, so that the directory name in NFS will change after creating the PVC.

This should be in the documentation, I've spent a day searching for this!
