kubernetes - 在同一kubernetes命名空间中创建多个PV和PVC

Question

我正在尝试在单个 namespace 中创建多个PV和PVC(针对每个PV)，但不允许这样做。这是预期的行为吗？我正在使用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

当我为新创建的PV创建新的PVC时，出现如下错误:


以下是PV和PVC的yaml:

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"

聚氯乙烯

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

Answer 1

您的集群具有ResourceQuota或LimitRange，且requests.storage设置为2Gi。因此，您无法使用20Gi创建PVC。
