为什么即使您的节点使用率较低、EC重新平衡也不起作用?

适用场景

  • NetApp StorageGRID
  • EC数据和复制的数据

问题解答

数据将仅平均分布于EC数据。

示例:
  • 节点1、节点2、节点3、节点4、节点5的使用率均约为90%
    • 其中30%是EC数据
    • 其中60%的使用量是复制的数据
  • 添加新节点(节点6)
  • EC重新平衡已成功运行
  • 现在、节点6的使用率约为25%
  • EC重新平衡再次运行、但不会执行任何移动

这是因为节点6仍然缺少复制的数据(这些数据会随着时间的推移而增长)。它不会获得比其他节点更多的EC数据。

节点1到6的EC数据量应大致相同。可通过"支持">"网格拓扑">"站点">"节点">"LDR">"存储"查看此配置
