  • Publication number: 20170123731
    Abstract: A management method and apparatus, and a storage medium, are capable of preventing the deterioration in the response performance of the overall system caused by the imbalance of the load between server apparatuses in a computer system equipped with a distributed shared file system. The management apparatus for managing a computer system is equipped with a distributed shared file system, and in cases where the load of a server containing a certain file is high upon updating that file, it selects another server with a low load as the temporary storage destination of the update data of that file, notifies the selected server as the write destination of the update data to the client, and, at the stage where the load of the server containing the file decreases, instructs the server retaining the update data to transfer the update data to the server containing the file.
