Summary:Methods, non-transitory computer readable media, and devices that dynamically adjust a logical unit number fault domain in a distributed storage area network environment includes determining when at least one of a plurality of nodes of a cluster is cut off from others of the plurality of nodes of the cluster. Any logical unit numbers (LUNs) owned by each of the plurality of nodes are identified. A fault domain for any of the identified LUNs owned by the at least one of the plurality of nodes determined to be cut off is adjusted from a distributed task set mode (DTM) of operation to a single task set mode (STM) of operation. This adjustment is made without any communication from the DTM operation to the STM operation to any of one or more host computing devices interacting with the cluster.
