Recovering From a Corrupt Quorum Disk

The quorum disk maintains the configuration data necessary for cluster recovery when a cluster node fails. If the quorum disk resource is unable to come online, the cluster will not start and all of the shared drives will be unavailable. If this situation occurs, and you need to run chkdsk on the quorum disk, you can start the cluster manually from the command line.

To start the cluster manually from a command prompt:

1Open a command prompt window.

2Select the cluster folder directory by typing one of the following:

cd \2000\cluster (for Windows 2000 Advanced Server), or cd \windows\cluster (for Windows Server 2003)

3Start the cluster in manual mode (on one node only) with no quorum logging by typing the following:

Clussvc -debug -noquorumlogging

MSCS starts.

4Run chkdsk /f on the disk designated as the quorum resource. To run the chkdsk /f utility:

a Open a second command prompt window. b Type:

chkdsk /f

5After the chkdsk utility completes, stop MSCS by pressing <Ctrl><c>.

6Restart the cluster service.

To restart MSCS from the Services console:

a Click the Start button and select Programs→ Administrative Tools→ Services. b In the Services window, right-click Cluster Service.

c In the drop-down menu, click the Start button. To restart MSCS from the command prompt:

a Open the second command prompt window that you opened in step 4a. b Type the following:

Net Start Clussvc

The Cluster Service restarts.

See the Microsoft Knowledge Base article 258078 located at the Microsoft Support website at www.microsoft.com for more information on recovering from a corrupt quorum disk.
