适用场景

NetApp StorageGRID 11.x

问题描述

问题描述在功能上是表面的、因为它不会影响网格功能。这是在 以下操作之一期间计算开销时的值:

  1. 在部署期间创建节点。
  2. 扩展期间创建节点。
  3. 节点恢复。
  4. 节点重新启动
  5. 升级

之后、一个或多个对象存储卷(RangeDB)的值将显示零使用量或用量过低。

注意:  只有在大量数据被占用后、才会注意到这一点。

这可以通过以下一个或多个示例来识别:

  • 各个卷的StorageGRID节点LDR概述显示的"复制的数据"或"EC数据"值不一致。

StorageGRID 节点LDR

  • 节点活动后空间使用量下降。

  • 一个节点显示不同的已用%:

StorageGRID 节点报告利用率过低

  • 在每个站点使用一个副本ILM规则时、一个站点的使用率高于另一个站点:

StorageGRID 节点LDR

  • 此使用量与ONTAP在Fabric Pool配置中报告的大小不同。
