适用场景

ONTAP 9
基于文件的Snap Restore
基于Snapshot的NetApp软件(Snap Creator (Commvault)、 SnapManagers、SnapCenter)
第三方备份应用程序使用与ONTAP的单文件快照还原集成
VMware本机快照(不是基于重做日志的传统VMware快照)

问题描述

手动或计划的Snapshot操作失败、并显示以下错误：

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关系的源卷、则手动或计划snapmirror update 可能会失败、并且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))
