An object of the present invention is to dynamically transfer a virtual
file server within a cluster that is configured by a plurality of file
servers in which virtual file servers are set up. A storage system
includes: a first file server; a second file server; and a disk
subsystem, in which: the first file server and the second file server
each include a virtual file server control unit that sets up the virtual
file server; the virtual file server includes a routing table that stores
path information necessary for communication; and the virtual file server
started up in the second file server determines a communication path by
using the routing table used by the virtual file server in the first file
server after taking a failover from the virtual file server of the first
file server to the second file server.
