A determination is made as to whether the selected storage area contains at least a predetermined amount of free space. If so, the predetermined amount of free space is allocated on the selected storage area to create an allocated storage area. A symbolic link to the allocated storage area is written in a directory associated with the virtual storage volume. Data destined for the virtual storage volume is then written in the allocated storage area.
