镜像替代节点的根聚合(MetroCluster IP 配置)

如果更换了磁盘,则您必须镜像灾难站点上新节点的根聚合。

步骤

  1. 在灾难站点上确定聚合: storage aggregate show
    示例
    cluster_A::> storage aggregate show
    
    Aggregate     Size Available Used% State   #Vols  Nodes            RAID Status
    --------- -------- --------- ----- ------- ------ ---------------- ------------
    node_A_1_aggr0
                1.49TB   74.12GB   95% online       1 node_A_1         raid4,
                                                                       normal
    node_A_2_aggr0
                1.49TB   74.12GB   95% online       1 node_A_2         raid4,
                                                                       normal
    node_A_1_aggr1   -         -     - unknown      - node_A_1         -
    node_A_2_aggr1   -         -     - unknown      - node_A_2         -
    4 entries were displayed.
    
    cluster_A::>
    
    
  2. 镜像根聚合之一: storage aggregate mirror -aggregate root-aggregate
    示例
    以下示例显示了此命令如何在镜像聚合时选择磁盘并提示确认。
    cluster_A::> storage aggregate mirror -aggregate node_A_2_aggr0
    
    Info: Disks would be added to aggregate "node_A_2_aggr0" on node "node_A_2" in
          the following manner:
    
          Second Plex
    
            RAID Group rg0, 3 disks (block checksum, raid4)
              Position   Disk                      Type                  Size
              ---------- ------------------------- ---------- ---------------
              parity     2.10.0                    SSD                      -
              data       1.11.19                   SSD                894.0GB
              data       2.10.2                    SSD                894.0GB
    
          Aggregate capacity available for volume use would be 1.49TB.
    
    Do you want to continue? {y|n}: y
    
    cluster_A::>
  3. 验证根聚合是否已完成镜像: storage aggregate show
    示例
    以下示例显示根聚合已完成镜像。
    cluster_A::> storage aggregate show
    
    Aggregate     Size Available Used% State   #Vols  Nodes       RAID Status
    --------- -------- --------- ----- ------- ------ ----------- ------------
    node_A_1_aggr0
                1.49TB   74.12GB   95% online       1 node_A_1    raid4,
                                                                  mirrored,
                                                                  normal
    node_A_2_aggr0
                2.24TB   838.5GB   63% online       1 node_A_2    raid4,
                                                                  mirrored,
                                                                  normal
                                                                  normal
    node_A_1_aggr1   -         -     - unknown      - node_A_1    -
    node_A_2_aggr1   -         -     - unknown      - node_A_2    -
    4 entries were displayed.
    
    cluster_A::>
  4. 对其他根聚合重复执行上述步骤。
