This tutorial is all about software raid-1 creation in linux.We will learn how to configure software raid-1 in linux having spare devices.In this lab we are going to use RedHat Enterprise Linux 5 to configure software raid-1 with spare device.We use spare device as a reserved disk which is used only when any of disk used in raid-1 failed.

As we know RAID-1 needs minimum of two disk and when any of disk among those two failed or crashes spare device replaces itself with that failed device or disk.
