适用场景

  • ONTAP 9
  • SVM灾难恢复
  • SnapMirror

问题描述

  • 某些SVM DR源卷已满 vserverDR 快照、这些快照不会滚动
  • 除非受影响的源卷达到 255个快照限制、否则SVM-DR关系仍会成功更新并保持运行状况良好

Failed to create snapshot copy on volume. Volume: volSource: Cannot exceed maximum number of Snapshot copies. Failed to create Snapshot copy on volume. Volume: volSource: Cannot exceed maximum number of Snapshot copies.

  • 受影响的卷也不会创建或滚出通过卷的快照策略管理的快照。

注意:在执行此知识库的解决方案步骤之前,请确保您的问题描述与所有三个要点匹配。如果SVM-DR中涉及的各个卷的底层vserverdr.* 关系因其他原因失败、则这些卷可能会保留多个SnapMirror Snapshot。这是正常行为。在这些情况下、请使用 snapmirror show -expand -fields last-transfer-error
