Abstract
A data processing system and method are disclosed for storing logical volume information used by a logical volume manager to create and manage a logical volume. The data processing system includes a plurality of storage devices. A plurality of physical partitions within the plurality of storage devices are specified. Each one of the physical partitions includes a plurality of sectors. The specified physical partitions are logically combined to create the logical volume. A first plurality of the sectors are reserved in each of the physical partitions for the logical volume information. The first plurality of sectors are located at the top of each of the physical partitions. The logical volume information is stored in the first plurality of sectors in each of the physical partitions. In this manner, the logical volume information is stored at the top of each of the physical partitions.
