SYMPTOMS
In a Microsoft Windows Server 2003 Microsoft Cluster Service (MSCS) environment, the MSCS service tries to recover the quorum disk when the MSCS folder in the quorum disk is inaccessible or does not exist. In this situation, the quorum disk may be damaged after MSCS tries to recover the quorum disk.

You can test whether the quorum disk is affected with this problem by running Chkdsk.exe in read-only mode. You can run Chkdsk.exe in read-only mode if you do not use the /f or /x options. For example, you can type chkdsk : at a command prompt, and then press ENTER. You can use the following switches:
 * /f Fixes errors on the disk.
 * /x Forces the volume to dismount if it is required.

If the quorum disk was affected with this problem and you run Chkdsk.exe in read-only mode, you may receive the following error message:

The type of the file system is NTFS.

The volume is in use by another process.

Chkdsk might report errors when no corruption is present.

Volume label is Volume.

WARNING! F parameter not specified. Running CHKDSK in read-only mode.

CHKDSK is verifying files (stage 1 of 3)... Deleting corrupt attribute record (112, &quot;&quot;) from file record segment 3.

File verification completed. Errors found.

CHKDSK cannot continue in read-only mode.

Important If this problem occurs, do not run Chkdsk.exe with the /f or /x option on the quorum disk. If you run Chkdsk.exe with the /f or /x option on the quorum disk, the data on quorum disk may be corrupted.



CAUSE
This problem occurs when the MSCS service tries to recover the quorum disk from a corrupted state. In this case, incorrect volume information data may be written to the quorum volume.

WORKAROUND
To work around this problem, you can recover the quorum disk when you apply this hotfix on all the MSCS nodes and then format the quorum disk. This procedure is useful if the quorum disk is already affected with this problem.

To recover the quorum disk when you apply this hotfix on all the MSCS nodes and then format the quorum disk, follow these steps:  Double-click the 217103_enu_ _zip.exe file, and then extract the file contents to a location that can be accessed by all the nodes in the MSCS cluster. Log on to the Windows Server 2003-based computer by using an account that has administrative permissions. Double-click WindowsServer2003-KB891189- -enu.exe. Back up the quorum disk by using the Windows Server 2003 Backup and Recovery Wizard or a third-party backup utility. Format the quorum disk by using the Disk Management utility.
