How to Use the /debug Option for Cluster Service

MORE INFORMATION

If the Cluster service fails to start because of a logon error for the service account, or another system-related error, the service may not have a chance to run. As a result, a new log file may not be created.

To run the Cluster service temporarily from a command prompt, use the following procedure:

1. Open a new command prompt window.
2. Change to the cluster directory on the local system. Usually, this is %SystemRoot%\cluster.
3. Type CLUSSVC /debugat the command prompt. The cluster service will send output to the window similar to what would normally be seen in the diagnostic log file. You may also capture this information in a file by using the following command syntax instead:
   

   CLUSSVC /debug > c:\debug.log
   						

4. At the point that you are satisfied that the Cluster service is running properly, you may use CTRL+C from the keyboard to stop the service.

NOTE: This method runs the service outside of the normal environment given by the Service Control Manager. To use this procedure, you must be logged on with administrative rights. Do not use the -debug option for normal use or for any length of time. The service does not run as efficiently with the option set; hence, this option is intended for temporary diagnostic use only.
