Scenario
When a split-brain error occurs in a QNAP High Availability (HA) cluster and you choose the “Preserve data on both nodes” recovery option, the system keeps each NAS device’s data separately. Data is not synchronized or merged automatically. You want to manually check and resolve any differences between the files on both devices.
Procedure
Method 1: Manually compare files using QNAP File Station
- Log in to both NAS devices.
- Open File Station and browse the folders you want to compare.
- In separate browser windows or tabs, compare file names, modification dates, and file sizes for the relevant folders.
Method 2: Use third-party folder comparison tools
- Mount shared folders from both NAS devices to your computer:
- Go to Control Panel > Network & File Services and ensure that file services (such as SMB, AFP, or NFS) are enabled.
- Mount the shared folders from both NAS devices to your computer using the file sharing protocol of your choice.
- Use a folder comparison tool you are familiar with (for example, FreeFileSync, Beyond Compare, or WinMerge) to scan and compare the contents of both shared folders.
- Based on the comparison results, manually decide which files to keep, merge, or remove.
Note
Automatic synchronization is not recommended because it may accidentally overwrite important data.

场景
当在 QNAP 高可用性 (HA) 群集中发生脑裂错误并选择“保留两个节点上的数据”恢复选项时，系统会分别保留每个 NAS 设备的数据。数据不会自动同步或合并。您需要手动检查并解决两个设备上的文件之间的任何差异。
步骤
方法 1：使用 QNAP File Station 手动比较文件
- 登录到两个 NAS 设备。
- 打开File Station并浏览您想要比较的文件夹。
- 在不同的浏览器窗口或标签页中，比较相关文件夹的文件名、修改日期和文件大小。
方法 2：使用第三方文件夹比较工具
- 将两个 NAS 设备的共享文件夹挂载到您的计算机：
- 进入控制台 > 网络和文件服务并确保文件服务（如 SMB、AFP 或 NFS）已启用。
- 使用您选择的文件共享协议将两个 NAS 设备的共享文件夹挂载到您的计算机。
- 使用您熟悉的文件夹比较工具（例如 FreeFileSync、Beyond Compare 或 WinMerge）扫描并比较两个共享文件夹的内容。
- 根据比较结果，手动决定保留、合并或删除哪些文件。
