Abstract
Proposed are a computer system and a management method capable of localizing influence from a failure of a physical node and preventing influence from the physical node failure from spreading. This computer system includes one or more servers that respectively provide a different single namespace to a client, a plurality of physical nodes that are capable of executing a plurality of virtual nodes that respectively belong to one of the single namespaces and provide a file sharing service to the client, and a management apparatus for managing the virtual nodes, and executes control of calculating a degree of contribution to a user for each of the virtual nodes, and selecting the virtual node to be migrated and the physical node of a migration destination so as to average, among the physical nodes, a total value of the degree of contribution of each of the virtual nodes running on the physical nodes based on the degree of contribution to the user for each of the virtual nodes, and migrating the virtual node selected as the migration target to the physical node selected as the migration destination.
