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。
