The system includes: a control table which includes availability indicia for indicating whether the control table is available and identification indicia for indicating ownership of the data storage volume. The system also includes control processes each executed on a client. The control processes request and acquire exclusive ownership of the control table to provide to the clients exclusive write access to the data storage volume.
