Scenario
When a RAID group is in degraded mode, inserting a replacement drive usually starts rebuilding automatically. In some cases, rebuilding does not start because the new drive is not automatically assigned to the degraded RAID group.
Note
This article only applies to RAID in degraded mode (the number of failed drives is still within RAID fault tolerance).
If the RAID is inactive or offline, use the inactive RAID recovery procedure instead.
Prerequisites
- Ensure the replacement drive capacity is equal to or larger than each current RAID member drive.
- If the new drive is not purchased from a reputable or authorized channel, the drive quality may be unreliable. Verify the drive can operate normally before use.
Solution
- Log in to the NAS through a web browser.
- Open Storage & Snapshots.
- Go to Storage > Storage/Snapshots.
- Select the target Storage Pool or Static Volume, and click Manage.
- In the degraded RAID group section, click Manage > Configure Spare Disk.
- Select the replacement drive, then click Apply.
Expected Result
RAID rebuilding starts immediately.
After rebuilding is complete, the RAID status returns to normal.
Troubleshooting
Issue: The replacement drive cannot be selected as a spare disk.
Checks:
- Confirm the drive capacity meets the requirement (equal to or larger than RAID member drives).
- Confirm the drive health is normal (no SMART warning, no bad blocks).
- Confirm interface and model compatibility with the NAS.
If the problem is not solved, collect system dump logs and contact QNAP Support.

场景
当 RAID 组处于降级模式时，插入替换驱动器通常会自动开始重建。在某些情况下，重建不会开始，因为新驱动器未自动分配给降级的 RAID 组。
注意
本文仅适用于降级模式下的 RAID（故障驱动器数量仍在 RAID 容错范围内）。
如果 RAID 处于非活动或离线状态，请使用非活动 RAID 恢复程序。
先决条件
- 确保替换驱动器的容量等于或大于每个当前 RAID 成员驱动器。
- 如果新驱动器不是从信誉良好或授权渠道购买的，驱动器质量可能不可靠。在使用前验证驱动器能否正常运行。
解决方案
- 通过网络浏览器登录 NAS。
- 打开存储与快照总管。
- 转到存储 > 存储 / 快照。
- 选择目标存储池或静态卷，然后点击管理。
- 在降级的 RAID 组部分，点击管理 > 配置备用磁盘。
- 选择替换驱动器，然后点击应用。
预期结果
RAID 重建立即开始。
重建完成后，RAID 状态恢复正常。
故障排除
问题：替换驱动器无法选择为备用磁盘。
检查：
- 确认驱动器容量符合要求（等于或大于 RAID 成员驱动器）。
- 确认驱动器健康状态正常（无 SMART 警告，无坏块）。
- 确认接口和型号与 NAS 兼容。
如果问题未解决，收集系统转储日志并联系QNAP 支持。
