Failures may occur during the execution of an operation by a user, for example, when a directory quota cannot be expanded, or when a directory lacking in storage resources, which are to be assigned from a file system, emerges even if the directory quota can be expanded. A storage subsystem of the invention is characterized by autonomously detecting quota expansion for a user; comparing the total of plural quotas with a limit value; and allocating a storage area set in a storage device in advance to the limit value if, based on the result of the comparison, the total value exceeds the limit value.
