Abstract
In a cluster of network devices using a consensus protocol for cluster synchronization, a full software rollback is performed by backing up a cluster state on a primary instance for the cluster, and then restarting all devices at the same time from a prior partition. The primary instance can then start a cluster management service and other devices can join the cluster using the consensus state stored by the primary instance.
