Abstract: In some embodiments, a cluster computing system notifies a host system that a first path to a resource in the cluster computing system is optimized and that a second path to the resource is non-optimized. The resource is owned or managed by a first computing node of the cluster computing system. The first path includes the first computing node. The second path includes a second computing node and an intra-cluster connection between the second computing node and the first computing node. A disruption in the intra-cluster connection, which prevents communication between the first and second computing nodes via the intra-cluster connection, is identified. During a time period in which the disruption exists, the host system is notified that the first path is optimized and that the second path is unavailable, and input/output operations between the host system and the resource via the first path are continued.
