适用场景

  • ONTAP 9
  • 删除工作负载

问题描述

  • 用户或命令(例如 qos statistics volume latency show Data 列)均显示高延迟。
  • 可能会看到(来自 event log show)与此相关的 EMS 消息,例如:
[wafl.zombie.susp.msg.threshold:notice]: WAFL(R) is experiencing zombie throttling possibly due to requests for large number of file deletions. [wafl_exempt08: wafl.cp.toolong:error]: Aggregate fas_01_DATA_AGGR experienced a long CP... This message occurs when a WAFL(R) consistency point (CP) takes longer than 30 seconds. A CP lasting more than 30 seconds might cause client latency and potentially a client outage.
  • 在 WAFL 免税处理域中,也可能会出现 CPU 利用率峰值较高的情况。
