Kubectl Pod 正在运行，但持久卷似乎无人认领?

Question

kubectl get pods：

NAME                         READY     STATUS    RESTARTS   AGE
wordpress-2942163230-47xzl   3/3       Running   0          20m

kubectl get pv：

NAME      CAPACITY   ACCESSMODES   RECLAIMPOLICY   STATUS      CLAIM     STORAGECLASS   REASON    AGE
pv0001    30Gi       RWX           Retain          Available                                      30m

kubectl get pvc：

NAME            STATUS    VOLUME    CAPACITY   ACCESSMODES   STORAGECLASS   AGE
task-pv-claim   Pending                                      manual         26m

为什么没有认领task-pv-claim？这是我的部署配置：

apiVersion: extensions/v1beta1
kind: Deployment
metadata:
name: wordpress
labels:
app: wordpress
spec:
replicas: 2
selector:
matchLabels:
app: wordpress

"-credential_file=/secrets/cloudsql/credentials.json"]
volumeMounts:
- name: cloudsql-instance-credentials
mountPath: /secrets/cloudsql
readOnly: true
- name: ssl-certs
mountPath: /etc/ssl/certs
- name: cloudsql
mountPath: /cloudsql
volumes:
- name: wordpress-persistent-storage
persistentVolumeClaim:
claimName: "task-pv-claim"
- name: cloudsql-instance-credentials
secret:
secretName: cloudsql-instance-credentials
- name: ssl-certs
hostPath:
path: /etc/ssl/certs
- name: cloudsql
emptyDir:

如果我执行kubectl describe，我会得到以下输出：

Volumes:
wordpress-persistent-storage:
Type:   GCEPersistentDisk (a Persistent Disk resource in Google Compute Engine)
PDName: wordpress-disk
FSType: ext4
Partition:  0
ReadOnly:   false

这实际上是以前的配置...奇怪的是，我确实对配置进行了kubectl apply，并删除了 pod(因此它将使用新配置重新启动(。

似乎我必须删除部署kubectl delete deployment wordpress而不仅仅是 pod。
