适用场景

  • Astra Trident
  • 支持后端驱动程序的CSI-Snapshot

问题描述

通过使用PVC、创建 CSI-SnapshotStorageClass 来从该快照创建PV,无论 storagePools StorageClass中存在哪个定义,克隆PVC都将始终在原始PVC所使用的相同的三项技术支持后端(例如SVM、驱动程序)中创建,而原始PVC也保存Snapshot信息。
 
例如、对于ONTAP、这意味着卷(及其所在的LUN)将显示在同一聚合和SVM中。
 
不能在支持三项技术的存储集中为具有相同(绝对不能不同)驱动程序的不同后端创建此类、例如、通过操纵StorageClass storagePools 设置。但是、即使尝试重新定位后端、此过程也不会失败、而是不会应用请求的存储库或后端更改。
