Corresponding partitions on disks 1, 3, and 5 were to be concatenated (not striped) to each other via RAID, while the partitions on disks 2, 4, and 6 served as mirrors of their corresponding partitions on disks 1, 2, and 5. All of these partitions were then to be mounted as directories (/p1, /p2, etc) in the file system.
