适用场景

StorageGRID 11.7.0.8之前的版本

问题描述

  • 启动SnapMirror操作后、单个存储节点的CPU比其他存储节点高
  • 将受影响节点置于维护模式会将高CPU切换到其他节点
  • 专用于SnapMirror操作的负载平衡器将TCP连接跟踪利用率显示为100%
  • na_conntrack的数量有所增加
  • 其他症状可能包括...
    • 通过对托管 负载平衡器端点的活动网关执行ping测试、出现大量数据包丢失。
    • 单个存储节点的S3流量/速率高于其对等节点。

下面的黄色(dc2h2)指标突出显示了正在处理更多S3请求的单个节点。
