A networking-based file share witness system includes a cluster system including a plurality of node devices, and a first networking device that is coupled to a network and to each of the node devices in the cluster system. The first networking device includes a first networking engine that transmits data between the network and the node devices in the cluster system. The first networking device also includes a first file share that stores a quorum file that is configured to provide, subsequent to the unavailability of at least one of the node devices in the cluster system, a first file share witness vote that is configured to be utilized with at least one node vote provided by at least one of the node devices in the cluster system that remains available in order to reach a quorum and allow the cluster system to continue to operate.
