红帽全球峰会1.3.18.4. 可变 CSI 节点可分配属性已正式发布
此功能允许动态更新节点可以处理的最大存储卷数量。如果没有此功能，当节点首次加入集群时，卷限制本质上是不可变的。如果环境改变（例如，如果您附加一个新的网络接口(ENI)与存储共享硬件 "slot"-OpenShift Container Platform 不会识别它对磁盘可用的插槽数量较少，从而导致 pod 卡住。
此功能只在 AWS Elastic Block Storage (EBS)上被支持。
OpenShift Container Platform 4.21 中引入了可变 CSI 节点可分配属性作为技术预览功能。在 OpenShift Container Platform 4.22 中，它作为正式发布(GA)的支持。
