k8s pv,pvc无法删除问题

一般删除步骤为：先删pod再删pvc最后删pv

但是遇到pv始终处于“Terminating”状态，而且delete不掉。如下图：

解决方法：

直接删除k8s中的记录：

1	kubectl patch pv xxx -p '{"metadata":{"finalizers":null}}'

参考信息：

This happens when persistent volume is protected. You should be able to cross verify this:

Command:

kubectl describe pvc PVC_NAME | grep Finalizers

Output:

Finalizers: [kubernetes.io/pvc-protection]

You can fix this by setting finalizers to null using kubectl patch:

kubectl patch pvc PVC_NAME -p '{"metadata":{"finalizers": []}}' --type=merge

实例操作：

[root@test-dev-master01 ~]# kubectl patch pvc test-es01  -p '{"metadata":{"finalizers":null}}' -n xitu-test
persistentvolumeclaim/test-es01 patched

[root@test-dev-master01 ~]# kubectl patch pvc datadir-zookeeper-zookeeper-0  -p '{"metadata":{"finalizers":null}}' -n xitu-test
persistentvolumeclaim/datadir-zookeeper-zookeeper-0 patched

[root@test-dev-master01 ~]# kubectl patch pv d-bp1flc3jh6rcc0le0x7y  -p '{"metadata":{"finalizers":null}}' -n xitu-test
persistentvolume/d-bp1flc3jh6rcc0le0x7y patched
