适用场景

ONTAP 9™3及更高版本

问题描述

  • 升级到ONTAP 9™3会突然导致QoS延迟从9.1或9.2增加
  • 升级后创建新的Vserver
  • 工作负载未更改
  • 延迟归因于QoS延迟中心。
    • 示例:
Cluster::> qos statistics volume latency show Workload Latency Network Cluster Data Disk QoS NVRAM Cloud ----------- ---------- ---------- ---------- ---------- ---------- ---------- ---------- -------- -total- 85.00us 85.00us 0ms 0ms 0ms 0ms 0ms 0ms vol1 84.00us 84.00us 0ms 0ms 0ms 0ms 0ms 0ms vol2 105.00ms 105.00us 0ms 0ms 0ms 104.1ms 0ms 0ms
