Abstract
A computer-implemented method for changing fencing modes in clusters may include (1) identifying a cluster of nodes configured with a fencing mode for resolving split-brain scenarios within the cluster, (2) identifying a request to reconfigure the cluster of nodes with a new fencing mode, (3) transmitting the request to each node in the cluster of nodes, (4) in response to the request, for each node in the cluster of nodes, testing the operability of the new fencing mode from the node, (5) receiving a message from the node indicating the success of the test; and, after receiving the message indicating the success of the test from every node within the cluster of nodes, and (6) reconfiguring each node within the cluster of nodes to use the new fencing mode. Various other methods, systems, and computer-readable media are also disclosed.
