Also keep in mind that dispersed cluster can only be expanded
by the number of initial nodes, eg starting with 4 nodes 3+1
can only evolve by adding 4 nodes 3+1, you cannot change the
default policy 3+1 to 4+1. So the granularity of the evolution
of the cluster is fixed at the beginning. <br class="">
