This article discusses the features of the local quorum resource on Windows Server 2003-based clusters.
In Microsoft Windows NT 4.0 and Microsoft Windows 2000 you can perform a local quorum installation of a server cluster to create a stand-alone cluster. This cluster is going to be a single server, with no shared disk. This functionality remains the same with Windows Server 2003; however, the Cluster service automatically creates the local quorum resource if it does not detect a shared disk (no special switches or installation procedure is required). Another new feature is the creation of a local quorum resource after it has been installed on any cluster.
When you run a cluster with a local quorum, the quorum information is stored in the %SystemRoot%\Cluster\MSCS folder. Because this information is stored locally, it is not replicated to other nodes in the cluster.
Caution Do not use a local quorum resource for the quorum on a multi-node cluster because this procedure can cause the loss of the cluster configuration data and the failure of the entire cluster. When you try to change the Quorum resource to a Local Quorum with a multi-node cluster, you receive the following error:
To create a local quorum resource after its installation:
An error occurred attempting to make '<local quorum resource name>' the quorum resource
The parameter is incorrect.
