How do I expand a storage pool in an HA cluster?

如何在HA 群集中扩展存储池？

When adding new disks to a storage pool, you can add the disks to an existing RAID group in the pool or use the newly added disks to create a new RAID group in the pool.

1. Insert the new disks into the same disk slots on both the active and passive nodes.
   
   Important

   Disks in the same disk slot must be of the same capacity on both nodes.
2. Go to Storage Manager > Storage Space.
3. Identify the pool to expand.
4. Under Action, click > Expand Pool.
5. Select an expansion method:
   • Create and add a new RAID group
   • Add new disk(s) to an existing RAID group
     If you select this method, also select the RAID group to expand.
6. Click Next.
7. Select the disks to be added, and then click Next.
   
   Note

   If the new disks do not appear on the list, check whether they are properly inserted in the same slots on both the active and passive nodes. The system only shows disks that are installed in the same slots on both nodes.
8. On the Summary page, confirm the configuration and click Expand.
   The system expands the storage pool on both nodes.

1. Identify the RAID group in the storage pool you want to expand.
   1. Go to Storage Manager > Storage Space.
   2. Identify the storage pool to expand.
   3. Under Action, click > Manage, and then go to the RAID tab.
      Storage Manager displays the RAID groups in the storage pool, and the disks used by each RAID group.
2. Verify that the RAID group's RAID type is RAID 1, 5 or 6.
   
   Note

   Only these RAID types currently support expansion by replacing disks one by one.
3. Disable all spare disks assigned to the RAID group.
   1. Go to Storage Manager > Disks > Disk.
   2. Identify the spare disk.
   3. Under Action, click > Disable Spare.
4. Note down all disk slots used by the RAID group.
   
   Tip

   To check the disk slots used by the RAID group, go back to Storage Manager > Storage Space, identify the storage pool, click > Manage, and then go to the RAID tab.
5. On the passive node, replace the disks one at a time.
   1. Replace an existing disk with a new disk that has a greater capacity.
      
      Important

      Do not replace more than one disk at a time.
   2. Wait for the system to rebuild the RAID group and the storage pool.
      
      Tip

      You can monitor the rebuild process in Storage Manager or High Availability Manager.
   3. Once the rebuild process is done, verify that both the disk's and pool's statuses are healthy.
      You can check the disk status in Storage Manager > Disks > Disk, and the pool status in Storage Manager > Storage Space.
   4. Repeat the previous steps until all disks have been replaced.
6. On the active node, replace the disks one at a time.
   Follow the same steps for replacing the disks on the passive node.
   
   Important

   Ensure the capacity of the disk in each disk slot on the active node matches that of the corresponding disk slot on the passive node.
7. After successfully replacing all disks in the RAID group on both nodes, check the storage pool capacity in Storage Manager.
   Once the total capacity of the storage pool is updated, the expansion is complete.

将新磁盘添加到存储池时，可以将磁盘添加到池中的现有RAID组，或使用新添加的磁盘在池中创建新的RAID组。

1. 将新磁盘插入活动和被动节点上的相同磁盘槽中。
   
   重要

   相同磁盘槽中的磁盘在两个节点上必须具有相同的容量。
2. 前往存储 管理器 > 存储 空间.
3. 识别要扩展的池。
4. 在操作, 点击 > 扩展池.
5. 选择扩展方法：
   • 创建并添加新的RAID组
   • 将新磁盘添加到现有RAID组
     如果选择此方法，还需选择要扩展的RAID组。
6. 点击下一步.
7. 选择要添加的磁盘，然后点击下一步。
   
   注意

   如果新磁盘未出现在列表中，请检查它们是否正确插入在活动和被动节点上的相同槽中。系统仅显示安装在两个节点相同槽中的磁盘。
8. 在摘要页面上，确认配置并点击扩展。
   系统将在两个节点上扩展存储池。

1. 识别您想要扩展的存储池中的RAID组。
   1. 前往存储管理器 > 存储空间.
   2. 识别要扩展的存储池。
   3. 在操作下，点击 > 管理，然后进入RAID标签。
      存储管理器显示存储池中的RAID组，以及每个RAID组使用的磁盘。
2. 验证RAID组的RAID类型是RAID 1、5或6。
   
   注意

   目前只有这些RAID类型支持通过逐个更换磁盘进行扩展。
3. 禁用分配给RAID组的所有备用磁盘。
   1. 前往存储管理器 > 磁盘 > 磁盘.
   2. 识别备用磁盘。
   3. 在操作, 点击 > 禁用备用.
4. 记下RAID组使用的所有磁盘槽位。
   
   提示

   要检查RAID组使用的磁盘槽位，请返回到存储管理器 > 存储空间，识别存储池，点击 > 管理，然后转到RAID标签。
5. 在被动节点上，一次更换一个磁盘。
   1. 用容量更大的新磁盘替换现有磁盘。
      
      重要

      不要一次更换多个磁盘。
   2. 等待系统重建RAID组和存储池。
      
      提示

      您可以在存储管理器或High Availability Manager中监控重建过程。
   3. 重建过程完成后，验证磁盘和池的状态是否健康。
      您可以在存储管理器 > 磁盘 > 磁盘中检查磁盘状态，以及在存储管理器 > 存储空间中检查池状态。
   4. 重复之前的步骤，直到所有磁盘都被替换。
6. 在主动节点上，一次更换一个磁盘。
   按照相同步骤更换被动节点上的磁盘。
   
   重要

   确保主动节点上每个磁盘槽位的容量与被动节点上对应磁盘槽位的容量匹配。
7. 在两个节点上的RAID组中成功替换所有磁盘后，检查存储池容量在存储管理器中。
   一旦存储池的总容量更新，扩展即完成。
