Abstract
Provided is a storage system that performs inter-node movement of parity and reconfiguration of a stripe when a node configuration is changed. The storage system includes a plurality of nodes and a management unit, in which the nodes are targets for data write and read requests, form a stripe by a plurality of data stored in different nodes and parity generated based on the plurality of data, and store the parity of the stripe to which the data under the write request belongs in a node different from the plurality of nodes that store the plurality of data so as to perform redundancy; and the management unit transmits, to the node, an arrangement change request to perform the inter-node movement of the parity and the reconfiguration of the stripe when the node configuration is changed.
