problem

Today there is a pv No, after you delete the associated pvc, pv deleted when problems arise on the machine, as follows, delete mysql-wordpress

[root@cbov10-devk8s56-117 mysql]# kubectl get pv|grep mysql
mysql-pv-volume                            5Gi        RWO            Retain           Bound    default/mysql-pv-claim              manual       153d
mysql-wordpress                            5Gi        RWX            Retain           Bound    basic-server/mysql-wordpress        mysql-wordpress       66m

[root@cbov10-devk8s56-117 mysql]# kubectl delete pv mysql-wordpress
persistentvolume "mysql-wordpress" deleted
^C
[root@cbov10-devk8s56-117 mysql]# kubectl delete pv mysql-wordpress

[root@cbov10-devk8s56-117 mysql]# kubectl get pv|grep mysql
mysql-pv-volume                            5Gi        RWO            Retain           Bound    default/mysql-pv-claim              manual       153d
