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.

Abstract translation: 在一些实施例中，集群计算系统通知主机系统到集群计算系统中的资源的第一路径被优化，并且资源的第二路径未被优化。 资源由集群计算系统的第一计算节点拥有或管理。 第一路径包括第一计算节点。 第二路径包括第二计算节点和第二计算节点与第一计算节点之间的集群内连接。 识别集群内连接的中断，其阻止第一和第二计算节点之间经由集群内连接的通信。 在存在中断的时间段期间，主系统被通知第一路径被优化并且第二路径不可用，并且主机系统和资源之间经由第一路径的输入/输出操作被继续。 p>

Abstract: 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.
