Dell SE500W Recovering From a Corrupt Quorum Disk

Maintaining Your Cluster 79

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:

1

Open a command prompt window.

2

Select 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)

3

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

the following:

Clussvc -debug -noquorumlogging

MSCS starts.

4

Run

chkdsk /f

on the disk designated as the quorum resource.

To run the

chkdsk /f

utility:

a

Open a second command prompt window.

b

Ty p e :

chkdsk /f

5

After the

chkdsk

utility completes, stop MSCS by pressing <Ctrl><c>.

6

Restart 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

.

c
