Quorum Disk (Quorum Resource)

The quorum resource is a common resource in the cluster that is accessible by all of the cluster nodes. Normally a physical disk on the shared storage, the quorum resource maintains data integrity, cluster unity, and cluster operations—such as forming or joining a cluster—by performing the following tasks:

•Enables a single node to gain and defend its physical control of the quorum resource — When the cluster is formed or when the cluster nodes fail to communicate, the quorum resource guarantees that only one set of active, communicating nodes is allowed to form a cluster.

•Maintains cluster unity — The quorum resource allows cluster nodes that can communicate with the node containing the quorum resource to remain in the cluster. If a cluster node fails for any reason and the cluster node containing the quorum resource is unable to communicate with the remaining nodes in the cluster, MSCS automatically shuts down the node that does not control the quorum resource.

•Stores the most current version of the cluster configuration database and state

data — If a cluster node fails, the configuration database helps the cluster recover a failed resource or recreates the cluster in its current configuration.

The only type of resource supported by the Cluster Service that can act as a quorum resource is the physical disk resource. However, developers can create their own quorum disk types for any resources that meet the arbitration and storage requirements.
