状态信息

适用场景

  • ONTAP 9
  • SnapMirror
  • SnapVault
  • 统一复制
  • 存储虚拟机灾难恢复( SVM DR )

问题描述

  • XDP SnapMirror或SVM DR反向重新同步 所需时间远远超过预期
  • 传输速度似乎非常慢、发送到目标的数据量也很低
  • snapmirror show  或者、ONTAP System Manager会在很长时间内报告SnapMirror关系状态为"正在准备"

  • 之后,卷和 SVM 复制关系 都可能会经历长时间的准备状态 snapmirror resync
  • 典型更新操作相比,准备操作可能运行的时间更长,并且似乎传输的数据更多
  • 在完成准备操作时、 snapmirror resync 卷SnapMirror或SVM DR的发生原因 速度会变慢。
