Abstract:
1. A computer-implemented method for resolving split-brain scenarios in computer clusters, the method being performed by a coordination point server comprising at least one processor, the method comprising: identifying a plurality of nodes within a computer cluster that are configured to collectively perform at least one task; receiving, at the coordination point server from a node within the computer cluster, a failure notification that identifies a link-based communication failure experienced by the node that prevents the nodes within the computer cluster from collectively performing the task; upon receiving the failure notification at the coordination point server, immediately causing the coordination point server to initiate an arbitration event within the computer cluster in order to identify a subset of the nodes that is to assume responsibility for performing the task subsequent to the link-based communication failure; wherein the coordination point server initiates the arbitration event by immediately prompting each node within the computer cluster to participate in the arbitration event.
