ABSTRACT:
The present invention is a grid quorum system, method and apparatus. In a cluster of resources in a computing grid, a resource locking method can include acquiring a temporally limited lock on a grid service in the computing grid. Upon expiration of the temporally limited lock, a renewal of the temporally limited lock can be requested. Subsequently, the temporally limited lock can be renewed if a renewal has been granted by the grid service in response to the request. Notably, the renewing step can include determining whether the cluster has been partitioned into a plurality of sub-clusters. If the cluster has been partitioned, a parent sub-cluster can be identified and the temporally limited lock can be renewed only if a quorum exists in the parent sub-cluster.
