Applicable Products
- QNAP QDA-A2AR (2 x 2.5-inch to 3.5-inch hardware RAID adapter)
- QNAP NAS models that support QDA-A2AR (for example, TS-673, TVS-x72 series)
Scenario
You have one or two 2.5-inch drives that are currently installed directly in your QNAP NAS and are members of a NAS software RAID group. You want to move these drives into a QDA-A2AR adapter so that they can share a single 3.5-inch bay, and you want to know if the NAS can keep the existing RAID data and configuration after this change.
Solution
No, you cannot keep the existing NAS RAID data when you move those drives into a QDA-A2AR.
When you configure the QDA-A2AR, it initializes the disks and creates its own hardware RAID metadata. This process overwrites the existing NAS RAID layout, so you should assume that all data on the drives will be erased.
Explanation
- The NAS uses software RAID and stores RAID metadata in a format specific to QTS or QuTS hero, while the QDA-A2AR uses its own hardware RAID metadata format.
- The QDA-A2AR must create and manage RAID on the adapter, which rewrites the disk structure and metadata.
- As with other hardware RAID enclosures, migrating active NAS RAID member disks into the adapter is not a data-preserving operation.
Recommended procedure
- Back up your data
- Create at least one complete backup of all data stored on the existing NAS RAID group, for example to another NAS, an external drive, or cloud storage.
- Verify that the backup is restorable before you change any RAID configuration or move disks.
- Power down the NAS and move the drives
- Shut down the NAS using the standard shutdown procedure in QTS or QuTS hero.
- Remove the 2.5-inch drives from their current NAS bays.
- Install the drives into the QDA-A2AR.
- Install the QDA-A2AR in the NAS
- Insert the QDA-A2AR (with the installed drives) into a 3.5-inch drive bay of the NAS.
- Power on the NAS and wait for it to boot.
- Create new storage on the NAS
- In QTS 5.2.x or QuTS hero h5.2.x, go to Storage & Snapshots > Storage > Storage/Snapshots.
- Create a new storage pool and volume, or a static volume, using the storage presented by the QDA-A2AR.
- Restore your data
- After the new volume is ready, restore your data from the backup to the new storage on the NAS.
- Confirm that important data is intact and accessible.
Limitations and risks
- You cannot preserve an existing NAS software RAID by moving its member drives directly into a QDA-A2AR.
- Do not move active NAS RAID member drives into the QDA-A2AR if you have not created and verified a backup.
If you proceed without a verified backup, data loss can be permanent and unrecoverable. Always back up important data before changing RAID configurations or moving drives between systems.

场景
您有一个或两个 2.5 英寸硬盘,目前直接安装在您的 QNAP NAS 中,并且是 NAS 软件 RAID 组的成员。您希望将这些硬盘移入 QDA-A2AR 适配器,以便它们可以共享一个 3.5 英寸插槽,并且您想知道在此更改后 NAS 是否可以保留现有的 RAID 数据和配置。
解决方案
不,当您将这些硬盘移入 QDA-A2AR 时,无法保留现有的 NAS RAID 数据。
当您配置 QDA-A2AR 时,它会初始化磁盘并创建自己的硬件 RAID 元数据。此过程会覆盖现有的 NAS RAID 布局,因此您应假设硬盘上的所有数据将被擦除。
解释
- NAS 使用软件 RAID,并以 QTS 或 QuTS hero 特定格式存储 RAID 元数据,而 QDA-A2AR 使用其自己的硬件 RAID 元数据格式。
- QDA-A2AR 必须在适配器上创建和管理 RAID,这会重写磁盘结构和元数据。
- 与其他硬件 RAID 机箱一样,将活动的 NAS RAID 成员磁盘迁移到适配器中并不是一个保留数据的操作。
推荐步骤
- 备份您的数据
- 为现有的 NAS RAID 组中存储的所有数据至少创建一个完整的备份,例如备份到另一个 NAS、外部硬盘或云存储。
- 在更改任何 RAID 配置或移动硬盘之前,验证备份是否可恢复。
- 关闭 NAS 并移动硬盘
- 使用 QTS 或 QuTS hero 中的标准关机程序关闭 NAS。
- 从当前的 NAS 插槽中移除 2.5 英寸硬盘。
- 将硬盘安装到 QDA-A2AR 中。
- 将 QDA-A2AR 安装到 NAS 中。
- 将安装好硬盘的 QDA-A2AR 插入 NAS 的 3.5 英寸硬盘槽中。
- 启动 NAS 并等待其启动完成。
- 在 NAS 上创建新的存储。
- 在 QTS 5.2.x 或 QuTS hero h5.2.x 中,前往存储与快照总管 > 存储 > 存储 / 快照。
- 使用 QDA-A2AR 提供的存储创建新的存储池和卷,或创建静态卷。
- 恢复您的数据
- 在新卷准备好后,从备份中将数据恢复到 NAS 上的新存储。
- 确认重要数据完好无损且可访问。
限制和风险
- 不能通过直接将成员硬盘移动到 QDA-A2AR 来保留现有的 NAS 软件 RAID。
- 如果没有创建和验证备份,请勿将活动的 NAS RAID 成员硬盘移动到 QDA-A2AR 中。
如果在没有验证备份的情况下继续操作,数据丢失可能是长期且不可恢复的。在更改 RAID 配置或在系统之间移动硬盘之前,请始终备份重要数据。
