k8s无法删除pv，pvc问题

问题：

在k8s里面创建了pv，pvc删除时报错：error: resource(s) were provided, but no name was specified

解决：

正确的删除顺序：
 
1.先删除pod
 
2.再删除pv 
 
3.在删除pvc

删除pv，pvc命令：

kubectl patch pv pvname -p '{"metadata":{"finalizers":null}}'
 
kubectl patch pvc pvcname -p '{"metadata":{"finalizers":null}}'

[root@master1 pv]# kubectl get pod
