Post quorum


"a cluster has 'quorum' if a majority of nodes are alive, communicating, and agree on the active cluster members. So in a thirteen-node cluster, quorum is only reached if seven or more nodes are communicating. If the seventh node dies, the cluster loses quorum and can no longer function."

why it is so...... why cluster cant work, if its majority nodes go down????

Because if it becomes broken into two parts, 6 on one side, 7 on the other due to some sort of network fault, only the 7 nodes will contiue to function, the other ones taking themselves out of the equation, meaning you aren't going to process pieces of data or whatever in isolation to other data.
