Scenario
I have a high-availability (HA) cluster where after a disk failure on one of the nodes, a RAID group and its parent storage pool became degraded. The following occurred:
- The system automatically used a designated spare disk to rebuild the degraded RAID group.
This converted the spare disk into a data disk and restored the storage pool. - I replaced the failed disk with a new disk.
- The system automatically made the new disk the new spare disk.
This caused inconsistent disk configuration between the two nodes of my cluster.
How can I safely swap the roles of the data and spare disks to make the disk configuration between nodes consistent again?
Instructions
The following steps allow you to safely swap roles between a data disk and a spare disk.
Note
- These steps can only be performed in Storage Manager, which is only available on the active node.
- You can manage disks on both nodes in Storage Manager, so there is no need to perform a switchover.
- If you need to perform these steps on both nodes, perform them on one node at a time.
- Log in to the active node as an administrator.
- Go to Storage Manager > Disks > Device.
- Optional: In the top-right corner, click the dropdown menu to select the other node in your HA cluster.
- Select the data disk to be replaced with a spare disk.
- Click Action, and then select Replace.
A new window opens. - Select Set as spare disk.
- Enter your account password.
- Click OK.
The system transfers all data from the selected disk to the spare disk.
The spare disk replaces the selected disk as a member of its RAID group, and the selected disk becomes the new spare disk.

场景
我有一个高可用性（HA）群集，其中一个节点的磁盘故障后，一个RAID组及其父存储池变得降级。发生了以下情况：
- 系统自动使用指定的备用磁盘重建了降级的RAID组。
这将备用磁盘转换为数据磁盘并恢复了存储池。 - 我用一个新磁盘替换了故障磁盘。
- 系统自动将新磁盘设为新的备用磁盘。
这导致我的群集的两个节点之间的磁盘配置不一致。
我如何安全地交换数据盘和备用盘的角色，以使节点之间的磁盘配置再次一致？
说明
以下步骤允许您安全地交换数据盘和备用盘之间的角色。
注意
- 这些步骤只能在存储管理器中执行，该管理器仅在活动节点上可用。
- 您可以在存储管理器中管理两个节点上的磁盘，因此无需进行切换。
- 如果需要在两个节点上执行这些步骤，请一次在一个节点上执行。
- 以管理员身份登录到活动节点。
- 前往存储管理器 > 磁盘 > 设备。
- 可选：在右上角，点击下拉菜单以选择您的HA 群集中的另一个节点。
- 选择要用备用磁盘替换的数据磁盘。
- 点击操作，然后选择替换。
一个新窗口打开。 - 选择设为备用磁盘。
- 输入您的账户密码。
- 点击确定。
系统将所有数据从选定磁盘传输到备用磁盘。
备用磁盘替换选定磁盘成为其RAID组的成员，而选定磁盘成为新的备用磁盘。
