    摘要: Provided is a method for controlling a computer system including a first server computer, a second server computer, at least one data storing device, and a client computer. The first server computer manages a first file system. The second server computer manages a second file system. The second file system includes data copied from the first file system. Data written in the second file system after data is copied from the first file system is stored in a shared volume. In the method, when a load on the second server computer is higher than a load on the first server computer, copy of the data stored in the shared volume to the first file system is started and a read request from a client computer is issued to the first server computer. Accordingly, it is possible to execute high-speed distribution of an access load of a storage system.

    摘要: A node 1 and a node 2 are in a mutual failover relationship and share information used in failover through a shared LU. Of filesystems FS1A, FS1B that are mounted at the node 1, the actions of level 1 are allocated to FS1A and the actions of level 2 are allocated to FS1B. The level 1 filesystem FS1A is taken over to the node 2 simultaneously with commencement of failover. The level 2 filesystem FS1B is taken over to the node 2 when an access request for FS1B is generated after commencement of failover. In this way, business services with high availability can be restarted at an early stage.
