NOTICE:

To avoid problems, you must follow this procedure if the evicted node is the last node in the cluster

a. Open a command prompt.

b. Type the following:

cluster node <node_name> /force

where <node_name> is the cluster node you are evicting from the cluster.

5. Close Cluster Administrator.

Running chkdsk /f on a Quorum Resource

You cannot run the chkdsk command with the /f (fix) option on a device that has an open file handle active. Because MSCS maintains an open handle on the

quorum resource, you cannot run chkdsk /f on the hard drive that contains the quorum resource.

To run chkdsk /f on a quorum resource's hard drive:

1. Move the quorum resource temporarily to another drive:

a. Right-click the cluster name and select Properties.

b. Click the Quorum tab.

c. Select another disk as the quorum resource and press <Enter>.

2. Run chkdsk /f on the drive that previously stored the quorum resource.

3. Move the quorum resource back to the original drive.

Recovering From a Corrupt Quorum Resource

The quorum resource maintains the configuration data necessary for cluster recovery when a cluster node fails. If the quorum 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 resource,

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 the following:

cd\winnt\cluster

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. Type:
