状态信息

适用场景

  • ONTAP 9.4到ONTAP 9.6 (含)
  • SnapMirror 

问题描述

  • 移动少量数据后、SnapMirror关系在传输状态下挂起。
  • 如果   满足以下所有条件、则会出现此问题描述:
    • SnapMirror源集群正在 运行ONTAP 9.4到9.6 (包括ONTAP 9.6)。此问题描述不会影响ONTAP 9.7及更高版本。
    •  问题描述启动时、SnapMirror源集群上已启用SnapMirror全局复制控制。
      • 可以 options replication.* 在源集群上使用命令查看SnapMirror全局复制控制。
    • 此问题描述会影响特定的SnapMirror源节点。
      • 挂起/卡住的SnapMirors可能具有一个相同的特定源节点、而同一集群中其他源节点的SnapMirors可能运行正常。
      • 在某些情况下、集群中的所有源节点都可能受到影响。
    • 在SnapMirror源节点的 EMS日志(位于/etc/log/EMS)中,将显示如下例所示的消息:
      Tue May 01 00:00:00 [ClusterA-01: repl_Handle_reg: repl.xfer.term.timed.out:error]: A component of a replication transfer with destination volume DSID '1234' or SnapMirror(R) tape ndmp session '' is taking a long time to terminate since it is busy performing some operation.
    • 在SnapMirror源节点的SKTrace日志(位于 /etc/log/mlog/sktrace.log)中,将显示如下例所示的消息:
      2019-05-01T00:00:00Z 34159448880650904 [5:0] REPL_0: repl_sender::NodeFactory::abortOrphanSenderNodes(): | Clearing orphan sender node with transfer uniq: 012345678-0123-0123-0123-0123456789ab
  • 在应用 此知识库文章中的解决方案之前、请确保 满足上述所有条件、并且已找到匹配的错误消息。 
    • 有 许多问题会以各种方式表现出来、这些问题可能会导致 SnapMirors挂起。
    • 如果遇到类似的问题描述、但发生原因不明确、请向NetApp技术支持创建案例。
