问题和答案

MDV 卷应如何位于聚合上?
  • 在 MetroCluster 配置中,最佳实践是将 MDV 卷放置在 2 个不同的镜像数据聚合上(位于分布在 2 个 HA 对上的 8 节点 MetroCluster 上)。 
  • 您可以将元数据卷从 MetroCluster 配置中的一个聚合移动到另一个聚合。
  • 当源聚合已停用或未镜像时,或者出于其他原因,您可能需要移动元数据卷。

 

  • 此操作步骤说明,如果两个 MDV 卷都托管在一个聚合上,则其中一个卷应移动到另一个聚合。
  • 请执行以下步骤:
    • 验证卷是否位于同一聚合上
      Cluster_A::> volume show -fields volume,aggregate
      vserver      volume                    aggregate      
      --------------- ------------------------------------------ -----------------------
      Cluster_A     MDV_CRS_6cc9b517a26d11e48b6100505697f7e6_A a1_required_data_aggr_1 <== MDV on same aggregate
      Cluster_A     MDV_CRS_6cc9b517a26d11e48b6100505697f7e6_B a1_required_data_aggr_1 <== MDV on same aggregate
      Cluster_A     MDV_CRS_7ec06dc9a26d11e4b97100505697f7e9_A b1_required_data_aggr_1
      Cluster_A     MDV_CRS_7ec06dc9a26d11e4b97100505697f7e9_B b2_required_data_aggr_1

       
    • 移动卷
      • 将权限设置为高级

Cluster_A::> set advanced

  • volume move另一个聚合运行二级元数据卷命令。
  • 按照MetroCluster 服务指南中的操作步骤 操作(移动MetroCluster 配置中的元数据卷)。
  • 卷移动完成后、元数据卷将位于两个单独的聚合上。
  • 将权限模式重新更改为admin

Cluster_A::> set -privilege admin
