1. Utilities to support 'new-style' RAID disks The Multiple Device driver's main goal is to group several disks or partitions together, making them look like a single block device. This includes linear adding of disks, RAID-0, -1, -4 and -5. 'New-style' RAID arrays have a lot features not present in the 'older' RAID arrays, including autodetection. Old arrays can be upgraded with this package, and it is mostly a good idea to use this package when creating new RAID arrays. In order to use this package, you must have a kernel with 'new-style' RAID drivers, which are included in stock kernels since the 2.4 series. For older kernels, you can find patches at http://people.redhat.com/mingo/raid-patches/. From Debian 3.0r0 APT
