Scenario
On the Control Panel > Quota page, some users may see that Used Size exceeds the quota limit or that Available space is shown as a negative value, even though the user does not appear to store that much data.
Root Cause
This issue is caused by a User ID (UID) mapping problem:
- QTS calculates user quota usage based on file ownership (UID).
- If files or folders are owned by a UID that is mapped to an unexpected or incorrect user account, their size will be counted toward that user’s quota.
- This can result in incorrect quota usage, including over-quota status or negative available space.
Solution
Warning: Deleting or disabling user accounts can affect user access, shared folder permissions, and applications that rely on those accounts. Before proceeding, ensure you understand the impact and back up important data if necessary.
Method 1: Find and fix file ownership using File Station
Use this method if the number of incorrectly owned files is manageable and you can adjust ownership from the web interface.
- Log in to QTS as an administrator.
- Open File Station.
- Use the advanced search function and fill with the issue user in "Owner" to find files or folders owned by the affected user.
- If too many results are returned, search one folder at a time instead of the entire NAS.
- Identify files or folders that should not belong to that user.
- Change their ownership to the correct user or to an administrator account.
After ownership is corrected, the system will automatically recalculate quota usage.
Method 2: Free the problematic UID and reassign it to an administrator
Use this method if many files are owned by a problematic UID and changing ownership manually is not practical.
- Delete the user account that currently uses the problematic UID. This action frees up that UID. (Existing files owned by that UID are not deleted.)
- Create a new administrator account.
- The system automatically assigns the newly created account the freed UID by default.
- Administrator accounts are not restricted by user quota.
- Existing files owned by that UID will no longer affect regular users’ quota usage.
Method 3: Disable the affected user and create a new account
Use this method if you prefer to keep the existing UID and data as-is, and simply provide the user with a fresh account and quota.
- Disable the user account that shows incorrect quota usage.
- Create a new user account for the same person.
- Assign the required permissions to the new account.

场景
在控制台 > 配额页面上，一些用户可能会看到已用空间超过了配额限制，或者可用空间显示为负值，即使用户看起来并没有存储那么多数据。
根本原因
此问题是由用户 ID (UID) 映射问题引起的：
- QTS 根据文件所有权 (UID) 计算用户配额使用情况。
- 如果文件或文件夹的所有权属于映射到意外或不正确用户账户的 UID，其大小将计入该用户的配额。
- 这可能导致配额使用不正确，包括超出配额状态或可用空间为负值。
解决方案
警告：删除或禁用用户账户可能会影响用户访问、共享文件夹权限以及依赖这些账户的应用程序。在继续之前，请确保您了解影响，并在必要时备份重要数据。
方法 1：使用 File Station 查找并修复文件所有权
如果错误拥有的文件数量可控，并且您可以通过网页界面调整所有权，请使用此方法。
- 以管理员身份登录 QTS。
- 打开File Station。
- 使用优异搜索功能，并在 "所有者 "中填写问题用户，以查找由受影响用户拥有的文件或文件夹。
- 如果返回的结果过多，请逐个文件夹搜索，而不是整个 NAS。
- 识别不应属于该用户的文件或文件夹。
- 将其所有权更改为正确的用户或管理员账户。
所有权更正后，系统将自动重新计算配额使用情况。
方法二：释放有问题的 UID 并将其重新分配给管理员
如果许多文件由有问题的 UID 拥有且手动更改所有权不切实际，请使用此方法。
- 删除当前使用有问题 UID 的用户账户。此操作释放该 UID。（现有由该 UID 拥有的文件不会被删除。）
- 创建一个新的管理员账户。
- 系统默认自动将释放的 UID 分配给新创建的账户。
- 管理员账户不受用户配额限制。
- 现有由该 UID 拥有的文件将不再影响普通用户的配额使用。
方法三：禁用受影响的用户并创建新账户
如果您希望保持现有 UID 和数据不变，并仅为用户提供新的账户和配额，请使用此方法。
- 禁用显示配额使用不正确的用户账户。
- 为同一人创建一个新的用户账户。
- 为新账户分配所需的权限。
