QNAP two-bay NAS
Scenario
A 2-bay NAS that may be configured with RAID 1 (mirroring), where both disks hold identical copies of your data for redundancy. Some users may wish to switch to using both disks independently—each as its own separate storage volume—to maximize total capacity or to dedicate each disk to a different purpose.
There is no in-place downgrade path from RAID 1 to single-disk volumes. Removing the RAID 1 configuration requires deleting the existing storage pool and volume, which erases all data on those disks. You must back up all data before proceeding.
Warning
This procedure is destructive. All data on the NAS will be permanently deleted when the storage pool is removed. Complete a full backup before continuing.
The overall process consists of three stages:
- Back up all data to an external USB storage device
- Delete the existing RAID 1 storage pool and volume
- Create two new independent single-disk storage pools and volumes
Stage 1: Back Up All Data to External USB Storage
-
Connect an external USB storage device with sufficient capacity to hold all data from the NAS.
-
Open File Station on the NAS.
-
Verify that the USB device appears under External Devices in the left panel.
-
Copy all folders and files from the NAS shared folders to the USB device.
-
After the copy is finished, verify that all critical files are present and accessible on the USB device before proceeding.
Stage 2: Reinitialize the NAS
Warning
The following steps will permanently erase all data on the NAS disks. Confirm your backup is complete before continuing.
Refer to How do I reinitialize the NAS?
Stage 3: Create Two Independent Single-Disk Storage Pools and Volumes
Repeat the following steps twice—once for each disk—to create two separate storage pools.
For Disk 1:
-
In Storage Manager, go to Storage/Snapshots.
-
Click Create > New Storage Pool.
-
Select only Disk 1 when prompted to choose disks.
-
Set the RAID type to Single (no redundancy).
-
Follow the wizard to confirm and create the storage pool.
-
After the pool is created, click Create > New Volume (or the wizard may prompt you automatically).
-
Assign the full capacity to the new volume and set a volume label (for example, Disk1_Storage).
-
Click Finish to complete the volume creation.
For Disk 2:
-
Repeat steps 2–8, selecting only Disk 2 and using a distinct volume label (for example, Disk2_Storage).
Screenshot needed: Storage Manager showing two separate storage pools, each with one disk and one volume.
-
After both volumes are created, open Control Panel > Shared Folders and create or reassign shared folders to each volume as needed.
Stage 4: Restore Data from USB Backup
-
Open File Station.
-
Under External Devices, locate the USB device containing your backup.
-
Copy your data from the USB device back to the appropriate shared folders on each disk.
-
Verify that all files are restored correctly.

QNAP 双盘位 NAS
场景
一个可以配置为 RAID 1（镜像）的双盘位 NAS，两个磁盘保存相同的数据副本以实现冗余。一些用户可能希望将两个磁盘独立使用——每个作为其自己的独立存储卷——以较大化总容量或将每个磁盘用于不同的目的。
没有从 RAID 1 降级到单盘卷的就地路径。移除 RAID 1 配置需要删除现有的存储池和卷，这将擦除这些磁盘上的所有数据。您必须在继续之前备份所有数据。
警告
此过程具有破坏性。当存储池被移除时，NAS 上的所有数据将被长期删除。在继续之前完成完整备份。
整体过程分为三个阶段：
- 将所有数据备份到外部 USB 存储设备
- 删除现有的 RAID 1 存储池和卷
- 创建两个新的独立单盘存储池和卷
阶段 1：将所有数据备份到外部 USB 存储
-
连接一个具有足够容量的外部 USB 存储设备以容纳 NAS 上的所有数据。
-
在 NAS 上打开File Station。
-
验证 USB 设备是否出现在左侧面板的外部设备下。
-
将 NAS 共享文件夹中的所有文件夹和文件复制到 USB 设备。
-
复制完成后，验证所有关键文件在 USB 设备上是否存在且可访问，然后再继续。
阶段 2：重新初始化 NAS
警告
以下步骤将长期擦除 NAS 磁盘上的所有数据。确认您的备份已完成后再继续。

阶段 3：创建两个独立的单盘存储池和卷
重复以下步骤两次——每个磁盘一次——以创建两个独立的存储池。
对于磁盘 1：
-
在存储管理器中，转到存储 / 快照。
-
点击创建 > 新建存储池。
-
在提示选择磁盘时，仅选择磁盘 1。
-
将 RAID 类型设置为单一（无冗余）。
-
按照向导确认并创建存储池。
-
池创建后，点击创建 > 新建卷（或向导可能会自动提示您）。
-
将全部容量分配给新卷并设置卷标签（例如，Disk1_Storage）。
-
点击完成以完成卷创建。
对于磁盘 2：
-
重复步骤 2 至 8，仅选择磁盘 2并使用不同的卷标签（例如，Disk2_Storage）。
需要截图：存储管理器显示两个独立的存储池，每个池有一个磁盘和一个卷。
-
在创建两个卷后，打开控制台 > 共享文件夹，并根据需要创建或重新分配共享文件夹到每个卷。
阶段 4：从 USB 备份恢复数据
-
打开File Station。
-
在外部设备下，找到包含您备份的 USB 设备。
-
将数据从 USB 设备复制回每个磁盘上的相应共享文件夹。
-
验证所有文件是否正确恢复。
