Abstract
The described technology is generally directed towards stretching a mapped storage clusters by adding nodes to a mapped cluster of mapped nodes and storage devices mapped to a real cluster of nodes and storage devices. Stretching the mapped cluster can provide additional computing resources to a set of storage devices. In one implementation, one or more newly mapped nodes are added to increase the node count of an existing mapped cluster to form a stretched cluster, with the storage devices distributed among the increased number of nodes; a mapping table is updated to relate the stretched cluster nodes and storage devices to the real cluster nodes and storage devices. Also described is un-stretching a stretched cluster, or further stretching a stretched cluster.
