Patent attributes
Proposed are a storage system and a failure handling method capable of quickly recovering from a degeneration configuration when a failure occurs while reducing a cost required for system construction. A storage system is provided with one or a plurality of storage devices provided in a cloud system, one or a plurality of storage nodes provided in the cloud system, and a cloud control device configured to control the cloud system. The storage node is configured to request the cloud control device to prepare a new storage node when a failure of another storage node is detected, determine whether the storage device allocated to the storage node in which the failure occurs is failed, and request the cloud control device to allocate the storage device allocated to the storage node in which the failure occurs to the new storage node when the storage device is determined to be not failed.
