红帽全球峰会8.2. 扩展 CSI 卷
您可以在存储卷被创建后，使用 Container Storage Interface (CSI) 来扩展它们。
不支持 缩小持久性卷(PV)。
先决条件
- 底层 CSI 驱动程序支持调整大小。请参阅"Additional resources"部分中的"OpenShift Container Platform 支持的 CSI 驱动程序"。
- 使用动态置备。
-
控制
StorageClass对象的allowVolumeExpansion被设置为true。如需更多信息，请参阅"启用卷扩展支持"。
流程
-
对于持久性卷声明(PVC)，将
.spec.resources.requests.storage设置为所需的新大小。 -
观察 PVC 的
status.conditions字段来查看调整大小是否完成。OpenShift Container Platform 在扩展过程中为 PVC 添加Resizing条件，该条件会在扩展完成后删除。
