Abstract
An information processing system includes a plurality of edge nodes to provide services relating to files, and a core node communicatively coupled to each of the edge nodes and configured to send or receive data of the files to or from the edge nodes and to manage the data of the files. Any one of the edge nodes is granted a first access right permitting update of the files, whereas any two or more of the edge nodes are granted a second access right to prohibit update of the files. The core node stores the access right granted to each of the edge nodes. When detecting that a failure has occurred in the edge node granted the first access right, the core node sends one of the edge nodes granted the second access right a first instruction to take over the first access right granted to the failed edge node.
