Cluster quorum with quorum nodes

Cluster quorum defines the minimum number of GPFS quorum nodes that must have the GPFS daemon actively running on them for the cluster to be operational. This number is half of the defined GPFS quorum nodes plus one, so it is a good idea to have an odd number of GPFS quorum nodes defined. Cluster quorum using only GPFS quorum nodes is the default quorum algorithm.
