Abstract
A computer-implemented method for preventing split-brain scenarios in high-availability clusters may include (1) detecting, at a first node of a high-availability cluster, a partitioning event that isolates the first node from a second node of the high-availability cluster, (2) broadcasting, from a health-status server and after the partitioning event has occurred, a cluster-health message to the first node that includes at least a health status of the second node that is based on whether the health-status server received a node-health message from the second node, and (3) reacting, at the first node and based at least in part on whether the first node received the cluster-health message, to the partitioning event such that the partitioning event does not result in a split-brain scenario within the high-availability cluster. Various other methods, systems, and computer-readable media are also disclosed.
