Abstract
In a storage system including a plurality of storage nodes and a plurality of storage devices that provide storage areas to the storage nodes, a cluster control unit that has detected occurrence of a failure in another storage node requests an external control device to execute a detach process of detaching a storage device allocated to a failure storage node from the failure storage node and an attach process of allocating the storage device to an alternative storage node. Then, the alternative cluster control unit restores, based on a log stored in a storage device allocated to a storage node in which a most recent failure has occurred among the storage nodes belonging to the same redundancy group as a failure storage control unit of the failure storage node, storage content of a memory of the alternative storage node.
