ABSTRACT:
The method of the present invention is useful in detecting the lack of majority cluster nodes within a cluster, and reorganizes the cluster membership to allow for running with less than a majority of nodes connected. As nodes become alive, they are added to the cluster until the original majority is reached, which then allows for the cluster to return to normal operation. Thus, the method of the present invention allows for the revival and reconstitution of a majority node set of clusters.
