当存储池运行不正常时，将显示以下消息。

Dec 14 04:06:21 [cluster01-01:raid.sp.unhealthy:notice]: Storage pool sp1 is unhealthy. Reason: One of the aggregates belonging to the storage pool is not in normal state.

发生此错误时，请检查存储池中是否存在任何 SSD 磁盘故障：

重构完成后，不正常状态应恢复为正常。

但是，如果将损坏的磁盘作为分区 SSD 放回系统中，则存储池将保持不正常，并显示以下状态：

cluster01::storage pool*> show -storage-pool sp1 -instance

                        Storage Pool Name: sp1
                     UUID of Storage Pool: 84afe3e1-a215-11e5-ac48-00a09854bc10

                  Storage Pool Total Size: 4.00TB
                         Is Pool Healthy?: false
                State of the Storage Pool: degraded
  Reason for Storage Pool Being Unhealthy: Storage pool has more number of disks than expected.
Job ID of the Currently Running Operation: -
               Is Allocation Unit Broken?: false

cluster01::storage pool*>

将显示以下消息：

cluster01::storage pool*> Dec 14 04:39:44 [cluster01-01:raid.sp.unhealthy:notice]: Storage pool sp1 is unhealthy. Reason: Storage pool has more number of disks than expected.

存储池将保持此状态，直到先前出现故障且更换的 SSD 从系统中物理删除或取消分区。

追加信息

请执行以下步骤，手动取消对从存储池中更换的 SSD 驱动器的分区。
注意： 只有当磁盘未被任何聚合使用时，才能从存储池中删除磁盘。

在执行以下步骤之前，请格外小心或联系 NetApp 技术支持。

1. 运行 storage pool show-disks -storage-pool <sp name> 命令以查找存储池中的现有驱动器。
2. 选择被重构替换并需要从存储池中删除的驱动器。
3. 运行 storage disk show -disk <disk name>" -fields diskpathnames, owner 命令以确定共享驱动器的所有者节点以及所有者节点上驱动器的本地名称。该 diskpathnames 字段将按 hostname:localname 格式提供名称。
4. 运行 storage disk partition show -container-disk <disk name> -fields owner-node-name 命令以了解此共享驱动器中的所有分区名称及其所有者节点。
5. 对于所有者与磁盘不同的分区，请运行 storage disk partition removeowner -partition <partition name> 和 storage disk partition assign -partition <partition name> -owner <disk owner> 命令更改所有者。
   完成此步骤后，磁盘及其所有分区的所有者应相同。
6. 进入所有者节点的节点 shell。
7. 运行 disk unpartition <disk name> 命令
   一旦磁盘取消分区，它将作为备用磁盘返回。
   一旦磁盘成为备用磁盘，则存储池应报告健康状态。
