AUTOMATED NODE FENCING INTEGRATED WITHIN A QUORUM SERVICE OF A CLUSTER INFRASTRUCTURE

A quorum service detects liveness failures of at least two failed nodes in a domain of a cluster infrastructure layer of a cluster environment within a limited time frame and adds the at least two failed nodes to a list of nodes set to pending to be fenced by a group leader node. The quorum service determines whether the at least two failed nodes include the group leader node. The quorum service, responsive to the at least two failed nodes not including the group leader node, triggers the group leader node to trigger at least one fencing operation to fence the at least two failed nodes in the list of nodes. The quorum service, responsive to the at least two failed nodes including the group leader node, sets a new node as the group leader node and triggers the new node set as the group leader node to trigger the at least one fencing operation to fence the at least two failed nodes in the list of nodes.
