I've had some difficulties(!) with raid disk failures in the past and often wanted an online resource to help. The RAID FAQ was getting out of date so I decided to start this wiki in the hopes of getting a community-manageable resource up.
If you need to contact me you can email me at david at dgreaves dot com at will.
Of course there is always the linux-raid list at email@example.com
See http://vger.kernel.org/majordomo-info.html for more details.
