From Linux Raid Wiki
I have spent 2 years messing with and learning in-depth software raid-5 on Ubuntu, culling much old ancient documentation. I found many new updates and things along the way in forums, in differing docs, and newer man pages. I documented my entire journey in excruciating detail. I hope to help bring all of this scattered knowledge together into one definitive, well-organized place.
