PVC can be put in different namespaces by setting metadata.namespace but PV cannot. PVC will pre-bind to the PV with the same name. My solution is just name PV&PVC pair with different for each name space,eg. efs-pv-namespace1, efs-pv-namespace2.

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nfs-caelus
  namespace: caelus
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: ""
  resources:
    requests:
      storage: 15Gi
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs-caelus
spec:
  capacity:
    storage: 15Gi
  accessModes:
    - ReadWriteMany
  nfs:
    server: 10.100.15.163
    path: "/"
---
apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nfs-nirvana
  namespace: nirvana
spec:
  accessModes:
    - ReadWriteMany
  storageClassName: ""
  resources:
    requests:
      storage: 15Gi
---
apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs-nirvana
spec:
  capacity:
    storage: 15Gi
  accessModes:
    - ReadWriteMany
  nfs:
    server: 10.100.15.163
    path: "/"
