如何對K8S的PV 和PVC擴容

直接改完後保存

然後強制刪除pvc

[root@k8s-master01 ~]# kubectl delete -f nfs-pvc001.yaml 
persistentvolumeclaim "nfs-pvc001" deleted
^C
[root@k8s-master01 ~]# 
[root@k8s-master01 ~]# 
[root@k8s-master01 ~]# 
[root@k8s-master01 ~]# kubectl get pvc
NAME         STATUS        VOLUME      CAPACITY   ACCESS MODES   STORAGECLASS   AGE
nfs-pvc001   Terminating   nfs-pv001   600Gi      RWX            nfs            70m
[root@k8s-master01 ~]# kubectl get pvc
NAME         STATUS        VOLUME      CAPACITY   ACCESS MODES   STORAGECLASS   AGE
nfs-pvc001   Terminating   nfs-pv001   600Gi      RWX            nfs            70m
[root@k8s-master01 ~]# kubectl patch pvc nfs-pvc001 -p '{"metadata":{"finalizers":null}}'
persistentvolumeclaim/nfs-pvc001 patched
[root@k8s-master01 ~]# kubectl get pvc
No resources found.
刪除成功
[root@k8s-master01 ~]# 
[root@k8s-master01 ~]# 
[root@k8s-master01 ~]# kubectl get pv
NAME        CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS     CLAIM                STORAGECLASS   REASON   AGE
nfs-pv001   800Gi      RWX            Recycle          Released   default/nfs-pvc001   nfs                     74m

[root@k8s-master01 ~]# vim nfs-pvc001.yaml 修改容量大小
[root@k8s-master01 ~]# kubectl apply -f nfs-pvc001.yaml 
persistentvolumeclaim/nfs-pvc001 created

[root@k8s-master01 ~]# kubectl get pv
NAME        CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS     CLAIM                STORAGECLASS   REASON   AGE
nfs-pv001   800Gi      RWX            Recycle          Released   default/nfs-pvc001   nfs                     75m
最後PV狀態悲劇了Released   

[root@k8s-master01 ~]# kubectl get pvc
NAME         STATUS    VOLUME   CAPACITY   ACCESS MODES   STORAGECLASS   AGE
nfs-pvc001   Pending                                      nfs            9s
[root@k8s-master01 ~]# kubectl get pvc
NAME         STATUS   VOLUME      CAPACITY   ACCESS MODES   STORAGECLASS   AGE
nfs-pvc001   Bound    nfs-pv001   800Gi      RWX            nfs            3m33s
[root@k8s-master01 ~]# kubectl get pv
NAME        CAPACITY   ACCESS MODES   RECLAIM POLICY   STATUS   CLAIM                STORAGECLASS   REASON   AGE
nfs-pv001   800Gi      RWX            Recycle          Bound    default/nfs-pvc001   nfs                     78m
[root@k8s-master01 ~]# 

最後把PV下面紅框的刪掉，保存即可恢復正常，原來的圖片資源還在
