Need to recover from a corrupted quorum log or disk on a Windows 2000 Cluster?

It can be tricky...but it can be accomplished.

I would suggest calling Microsoft PSS as a FIRST result, but if you want to follow these steps you can.

The following are steps that I went through to recover a corrupted quorum disk.

NOTE - I cannot guarantee that problems resulting from a corrupted quorum can be solved. Use the information provided at your own risk.


If you cluster service is running, then you will need to stop the service. I had only one cluster node running when I attempted these steps.
1. Open Computer Management
2. Go to Services and Applications
3. Services
4. On the Action menu, click Stop
5. On the Action menu, click Properties
6. Under Current Status, in the Start Parameters, type in -noquorumlogging then click start
7. Run Check Disk on the Quorum drive.

If the disk comes back clean, then it is most likely the Quolog.log file that is corrupted. You must delete the MSCS\Quolog.log file plus any MSCS\*.tmp files on the Quorum disk.

8. Stop the Cluster Service.
9. Restart the Cluster Service without any start parameters.

NOTE-When you start the cluster service without a quorum log, you can lose recent changes.
