Creating multiple PV and PVC in same kubernetes namespace

I am trying to create multiple PV and PVC(for each one of the PV) in a single namespace and it is not allowing me to do so. Is this an expected behavior? i am using NFS. 

NAME                          CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS      CLAIM                                                 STORAGECLASS   REASON    AGE
nfs-office-tools-service-pv   70Gi       RWX            Retain           Bound       office-tools-service-ns/nfs-office-tools-service-pv   manual                   4d
nfs-perfqa-jenkins-pv         20Gi       RWX            Retain           Available                                                         manual                   8m
nfs-perfqa-pv                 2Gi        RWX            Retain           Bound       perfqa/nfs-perfqa-pvc         

                    manual                   17d

When i create a new PVC for the newly created PV, it is giving error as below: enter image description here

Below are the yaml for PV and PVC:

PV.yaml

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs-perfqa-jenkins-pv
  namespace: perfqa
spec:
  storageClassName: manual
  capacity:
    storage: 20Gi
  accessModes:
    - ReadWriteMany
  hostPath:
    path: "/nfs_share/docker/test/jenkins"

PVC.yaml

apiVersion: v1
kind: PersistentVolumeClaim
metadata:
  name: nfs-perfqa-jenkins-pvc
  namespace: default
spec:
  storageClassName: manual
  accessModes:
    - ReadWriteMany
  resources:
    requests:
      storage: 20Gi

Your cluster has ResourceQuota or LimitRange with requests.storage set to 2Gi. So you cannot create PVC with 20Gi.

First of all note that persistent volume is defined at cluster level. it is not defined at namespace level.

correct pv definition as below

apiVersion: v1
kind: PersistentVolume
metadata:
  name: nfs-perfqa-jenkins-pv
spec:
  storageClassName: manual
  capacity:
    storage: 20Gi
  accessModes:
    - ReadWriteMany
  hostPath:
    path: "/nfs_share/docker/test/jenkins"

There is no issue with pv. it is created and is available

nfs-perfqa-jenkins-pv         20Gi       RWX            Retain           Available

also check for resourceQuota in default namespace. You might have set max storage limit to 2GB
