Suggest to set reclaimPolicy Retain on datadir PV

[camuffo]

The README should mention that StorageClasses usually provision PVs with reclaimPolicy: Delete.
Suggest to manually patch the reclaimPolicy to be Retain, to preserve valuable data.

kubectl -n gs patch pv PV_NAME -p '{"spec":{"persistentVolumeReclaimPolicy":"Retain"}}'

Hi @camuffo

Please try this instead:

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: my-pvc
  annotations:
    "helm.sh/resource-policy": keep
spec:
  accessModes:
    - ReadWriteOnce
  resources:
    requests:
      storage: 10Gi

the use of annotations to prevent PVC deletion on unistall. Also test what happens on reinstall / upgrade. Do the PVCs reattach to the PODs automatically?
