  • Reconciliation of asymmetric topology in a clustered environment
    Patent number: 10164856
    Abstract: Provided are techniques for the orderly shutdown of a node within a cluster in the event of asymmetric topology maps, comprising receiving, at a first node, a plurality of heartbeats, each heartbeat corresponding to a particular, corresponding other node in the cluster and comprising information on a topological map corresponding to each particular other node's view of the cluster generating, by the first node, a topological map of the cluster based upon the information comprising the heartbeats; comparing the topological map of the cluster and the topological maps corresponding to each node; in response to a determination that the topological maps of the duster and each node are not in agreement, determining the connectivity of the first node with respect to the cluster and in respond to a determination that the first node has the lowest connectivity within the cluster, shutting down the first node.
