SYMPTOMS

  • You have uninstalled File Server Resource Manager without removing the quotas and quota templates you have already created. You have then re-installed File Server Resource Manager on the same computer.
  • When you open the File Server Resource Manager console, you see there are no quotas defined, but when you try to create a new quota and apply it on a folder, you get the following error:
 
     Can't create quota in the given path as a quota already exists for that path.
     An unexpected error has occurred. Please check application event log for more information
 
  • The following events are logged in the Application Event Log

CAUSE

When you define quotas, File Server Resource Manager (FSRM) stores information about these quotas in the quota.xml,  quota.md, and databasefilescreen files in the \System Volume Information\SRM folder on the drive that the quotas were imposed initially. During a clean uninstallation of the FSRM, these files are removed. However, if the uninstallation was not completed successfully and you re-installed FSRM on the same computer, these files still remain and are not over-written by a subsequent re-installation of FSRM.

RESOLUTION

The resolution involves recreating the quota.xml,  quota.md, and databasefilescreen files in the \System Volume Information\SRM folder on the drive that the quotas were imposed initially.
 
WARNING: You will lose all your quota definitions and quota template configuration when you follow this procedure. Perform these steps only if you wish to start configuring File Server Resource Manager from scratch.
 
The System Volume Information folder can be found on the root folder of any Windows volume. This is folder is critical for the functioning of the operating system, hence it is accessible only by the SYSTEM account. It is a hidden system folder, which can be made visible if you configure the Folder Options in Windows Explorer to Show hidden and system files.
 
Since only the SYSTEM account can access this folder, we will use a workaround to get to this folder. We will use the AT command to schedule a job to open the Command Prompt (cmd.exe). The AT command starts cmd.exe in the SYSTEM account context and you will be able to access the \System Volume Information\ folder.
 
  1. Open Command Prompt.
     
  2. Type the command:
    AT [time in hh:mm] /interactive cmd.exe

    where [time in hh:mm] is the next minute with respect to your system clock. For example, if the time now is 20:09, then the command should be
    AT 20:10 /interactive cmd.exe
     
  3. Wait for the next minute. In the above example, wait till 20:10. The Command Prompt window will appear. This window is running under the SYSTEM user context.
     
  4. Type each of the following commands in the Command Prompt window:
    CD \System Volume Information\SRM
    ATTRIB quota.xml -s -h
    ATTRIB quota.md -s -h
    ATTRIB databasefilescreen -s -h
    DEL quota.xml
    DEL quota.md
    DEL databasefilescreen
    exit
     
  5. Re-install File Server Resource Manager. The above files will be recreated. The previous quota settings will be lost and you can recreate your quotas.
