由于快照支持的克隆，不允许进行快照操作
CONTAP-302033
适用于
- ONTAP 9
- 基于文件的快照恢复
- 基于快照的 NetApp 软件 (Snap Creator (CommVault), SnapManagers, SnapCenter)
- 使用与 ONTAP 的单文件快照恢复集成的第三方备份应用程序
- VMWare 原生快照（而非经典的基于重做日志的 VMWare 快照）
问题
- 手动或计划的快照操作失败，并出现以下错误：
1/5/2019 09:05:00 Cluster1-01 ERROR wafl.snap.create.skip.reason: vol01 <UUID>: Skipping creation of hourly.<time> Snapshot copy (Snapshot operation not allowed due to clones backed by snapshots. Try again after sometime.).
- 如果受影响的卷是 Snapmirror 关系的源，则手动或计划
snapmirror update可能会失败，并last-transfer-error显示：
Last Transfer Error: Failed to create Snapshot copy <snapmirror.snapshotname> on volume <svm>:<volume>. (Failed to create Snapshot copy <snapmirror.snapshotname> on volume <svm_uuid>:<volume_name>. (Volume has clones backed by snapshots))
- ONTAP ems 日志显示针对 SnapCenter Plug-in for VMware vSphere 的
app.log.error事件。
