一般删除步骤为:先删pod再删pvc最后删pv。

遇到的问题

但是遇到pv始终处于“Terminating”状态,而且删不掉。如下图:

解决方法

直接删除k8s中的记录:

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@binghe ~]# kubectl patch pvc test  -p '{"metadata":{"finalizers":null}}' -n k8s-test
persistentvolumeclaim/test patched
[root@binghe ~]# kubectl patch pvc datadir-zookeeper-zookeeper-0  -p '{"metadata":{"finalizers":null}}' -n k8s-test
persistentvolumeclaim/datadir-zookeeper-zookeeper-0 patched
[root@binghe ~]# kubectl patch pv d-bp1flc3jh6rcc0le0x7y  -p '{"metadata":{"finalizers":null}}' -n k8s-test 
persistentvolume/d-bp1flc3jh6rcc0le0x7y patched
