适用场景

Cloud Volumes ONTAP ( CVO )

问题描述

在 Azure 高可用性( HA )配置 中,即使 Azure CVO 处于闲置状态或仅提供少量客户端 IOPS ,编号最高的 CPU 也可能以 100% 或接近 100% 的 CPU 利用率运行。

 cluster::> set diag cluster::*> node run -node cluster-01 sysstat -M -c 3 1 ANY1+ ... ANY16+ AVG CPU0 CPU1 CPU2 CPU3 CPU4 CPU5 CPU6 CPU7 CPU8 CPU9 CPU10 CPU11 CPU12 CPU13 CPU14 CPU15 Nwk_Lg ... 100% 0% 9% 3% 3% 2% 3% 2% 2% 2% 2% 3% 3% 3% 3% 2% 2% 3% 100% 0% 100% 0% 12% 7% 5% 6% 5% 5% 6% 5% 5% 6% 6% 11% 6% 5% 6% 7% 100% 0% 100% 0% 8% 1% 1% 1% 1% 1% 2% 1% 2% 1% 1% 11% 1% 5% 1% 1% 100% 0% 

注:

  • 此示例显示了一个包含 16 个 CPU 核的配置。
  • CPU15 始终 100% 地利用,而不会产生任何实际用户工作负载。
  • 上述命令输出会被截断,仅会突出显示最后一个 CPU 核心(CPU15)的高 CPU 利用率。
