Abstract
Systems and method for expanding a cluster with nodes before an upgrade so that the cluster can handle a failover event during an upgrade and still continue operating. The system and method includes receiving, at a processor, a signal indicating a cluster is about to commence an upgrade; computing, by the processor, a first number of nodes; adding, by the processor, the first number of nodes from a network to the cluster before the upgrade is performed on the cluster; receiving, at the processor, a signal indicating the cluster finished the upgrade; and removing a second number of nodes that is no greater than the first number of nodes from the cluster after the processor receives the signal indicating the upgrade is complete.
