Diagnosing Windows Cluster Issues

Working with a Microsoft Engineer on a cluster issue today. He showed me a really cool command to get some diagnostic log information about cluster related problems.

The command to get this information is:

cluster.exe ClusterName log /gen

You may receive the following error:

System error 1825 has occured (0x00000721)
A security package specific error occured.



If you receive this error remove the ClusterName.

cluster log /gen

The cluster debug log file get stored in the following location after running this command:

c:\windows\cluster\cluster.log
