Overview
Security Center protects your NAS by detecting abnormal file activities and may warn of ransomware or other malicious behaviors. One of its protective actions is “Set this shared folder to read-only mode”. When enabled, this action is triggered automatically if the number of abnormal file activities in a monitored shared folder exceeds the defined threshold. This helps contain potential damage.
However, to ensure service continuity and stability in a High Availability (HA) setup, this action behaves differently in HA mode, compared with Standalone mode. This FAQ explains how the feature functions in both configurations.
Limitations
The “Set this shared folder to read-only mode” action behaves differently depending on whether your NAS is running in standalone mode or in HA mode.
| Configuration | Supported | Behavior |
|---|
| Standalone Mode | Yes | - When abnormal file activity exceeds the configured threshold, and the action is enabled, Security Center will automatically set the affected shared folder to read-only mode.
- This helps stop further potential data loss or corruption. |
| HA (High Availability) Mode | No | - Even if the action is configured, Security Center will not set the shared folder to read-only mode when abnormal activity occurs.
- This restriction is in place to preserve HA system stability and avoid conflicts between active and passive nodes. |
| After HA Is Disabled (Reverts to Standalone) | Yes | - Once the NAS is no longer in an HA configuration, the action will function normally again.
- If abnormal file activity is detected beyond the threshold, the shared folder will be set to read-only as configured. |
This limitation in HA mode is designed to ensure high availability and operational integrity.

概述
安全中心通过检测异常文件活动来保护您的 NAS，并可能警告勒索软件或其他恶意行为。其保护措施之一是“将此共享文件夹设置为只读模式”。启用后，如果监控的共享文件夹中的异常文件活动数量超过定义的阈值，则此操作会自动触发。这有助于遏制潜在损害。
然而，为了确保服务的连续性和稳定性高可用性 (HA)设置中，此操作在 HA 模式下的行为与独立模式不同。本常见问题解答解释了该功能在两种配置中的运作方式。
限制
“将此共享文件夹设置为只读模式”操作的行为取决于您的 NAS 是在独立模式还是在 HA 模式下运行。
| 配置 | 支持 | 行为 |
|---|
| 独立模式 | 是 | - 当异常文件活动超过配置的阈值，并且启用了该操作时，安全中心将自动将受影响的共享文件夹设置为 只读模式。
- 这有助于阻止进一步潜在的数据丢失或损坏。 |
| HA (高可用性) 模式 | 否 | - 即使配置了该操作，当发生异常活动时，安全中心将 不会 将共享文件夹设置为只读模式。
- 此限制旨在保持 HA 系统的稳定性并避免主动和被动节点之间的冲突。 |
| HA 禁用后（恢复为独立模式） | 是 | - 一旦 NAS 不再处于 HA 配置中，该操作将恢复正常功能。
- 如果检测到超过阈值的异常文件活动，共享文件夹将按配置设置为只读。 |
HA 模式下的此限制旨在确保高可用性和操作完整性。
