See documentation for the latest supported version 3 or the latest supported version 4.3.2.6. 持久性卷的重新声明策略
持久性卷重新声明（reclaim）策略指定了在卷被释放后集群可以如何使用它。卷重新声明政策包括 Retain、Recycle 或 Delete。
-
Retain策略可为那些支持它的卷插件手动重新声明资源。 -
Recycle策略在从其请求中释放后，将卷重新放入到未绑定的持久性卷池中。
重要
在 OpenShift Container Platform 4 中， Recycle 重新声明策略已被弃用。我们推荐使用动态置备功能。
-
Delete策略删除 OpenShift Container Platform 以及外部基础架构(如 AWS EBS 或者 VMware vSphere)中相关的存储资源中的PersistentVolume。
注意
动态置备的卷总是被删除。
