由于删除工作负载而导致延迟较长
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。
