问题描述

尝试更新/重新同步失败，无法建立 SVM DR SnapMirror 关系
SnapMirror 报告未找到常见快照副本：

Transfer for volume "<volume>" failed. Reason: No common Snapshot copy found between <SVM>:<volume> and <SVM-DR>:<volume>. Delete the volume using the (privilege: advanced) "volume delete -force" command. Then, perform a SnapMirror resync using the "snapmirror resync" command. Execute "snapmirror show -destination-vserver <SVM-DR> -fields last-transfer-error,unhealthy-reason -expand" to check if the constituent volumes have encountered errors.

有时，无法删除目标卷：
例如：

cluster_dst::*> set advanced

cluster_dst::*> volume delete -vserver SVM1 -volume volume1 -force true Error: command failed: Volume volume1 in Vserver SVM1 must be offline to be deleted. cluster_dst::*> volume offline -vserver SVM1 -volume volume1 -force true Warning: Forcing offline volume volume1 in Vserver SVM1 can potentially disrupt access to files in other volumes. Do you want to continue? {y|n}: y vol offline: Error off lining volume "SVM1:volume1". Error while deleting junction.
