When using the recommended template for persistent volume claims in the wiki:

kind: PersistentVolumeClaim
apiVersion: v1
metadata:
 name: test-ceph-pvc
spec:
 accessModes:
  - ReadWriteMany
 resources:
  requests:
   storage: 2Gi
 storageClassName: csi-cephfs-sc

I get an error ValidatingAdmissionPolicy 'label-user-validating-admission-policy' with binding 'label-validating-admission-policy-binding' denied request: The metadata label 'eidf/user' is missing or has an empty value set.

I fixed it by introducing the missing label field and all was fixed. I think the template should be updated to avoid friction. I found it on the Running a Pytorch Pod page and Persistent Volumes.
