NetApp Element 软件

问题解答

概述

NetApp 建议,在运行 Element Software 的集群中混用存储节点类型时,任何一个节点都不应超过集群总容量的 33% 。

例如,在具有四个 SF 系列 4805 节点的集群中,可以自行添加的最大节点是 SF 系列 9605 。在这种情况下,集群容量阈值是根据最大节点的潜在损失计算的。

集群警报

违反三分之二规则将导致以下集群警报:

  • NetApp SolidFire ActiveIQ 中的错误代码:
    • unbalancedMixedNodes
  • 详细信息:
    • A single node accounts for more than one-third of the storage cluster's capacity. Contact NetApp Support for assistance.
    • The mix of node capacities in the cluster is unbalanced because node ID <#>, "<NAME>" is greater than 33.3333% of the cluster's capacity.

追加信息

  • 有关详细信息,请参阅 用户文档中的管理节点一节
  • 删除触发警报的节点时:确保其余节点具有足够的容量
  • 删除触发警报的多个节点时:逐个删除
