问题解答

如果输出显示节点处于 部分交还 状态,则表示根聚合已交还,但一个或多个 SFO (数据)聚合的交还处于待定状态或失败状态。

  • 运行storage failover show命令时,将显示类似于以下内容的输出:


::> storage failover show
                              Takeover
Node             Partner        Possible State Description
--------------   -------------- -------- -------------------------------------
Node-1           Node-2      true     Connected to Node-2.
Node-2           Node-1      true     Connected to Node-1,Partial giveback

 

  • 但是cluster show,命令输出不会显示任何问题,并且数据将正常提供:


::*> cluster show
Node                 Health  Eligibility   Epsilon
-------------------- ------- ------------  ------------
node-01              true    true          false
node-02              true    true          false
2 entries were displayed.

可能会发生两种类型的故障转移
  • CFO (集群故障转移):这是根聚合的故障转移。
  • SFO (存储故障转移):这是数据聚合的故障转移。
