Hi Dave, the last person I helped with RAID1 I pointed over to an excellent and detailed posting at <a href="http://www.howtoforge.com/how-to-set-up-software-raid1-on-a-running-system-incl-grub2-configuration-ubuntu-10.04">http://www.howtoforge.com/how-to-set-up-software-raid1-on-a-running-system-incl-grub2-configuration-ubuntu-10.04</a> There is so much detail on there is would be an article in it's own right, and I do not think putting it in the grub2 documentation would sit well. There is also the small matter of the rather excellent 10.04LTS server documentation for RAID at <a href="https://help.ubuntu.com/10.04/serverguide/C/advanced-installation.html">https://help.ubuntu.com/10.04/serverguide/C/advanced-installation.html</a> I've seen both methods used, using the ubuntu server system just requires the use of tasksel to put on gui ubuntu (GNOME), kubuntu or xubuntu versions on [lxde isn't a tasksel yet '-( ] The server edition covers the three types of RAID commonly used.

While I try to keep the <a href="https://help.ubuntu.com/community/Grub2" target="_blank">https://help.ubuntu.com/community/Grub2</a> current, there are several glaring lapses. The first is discussion of RAID; another is booting from USB devices. I have no Grub 2 experience with either and thus have not been able to contribute anything on these topics in the community doc. If anyone has experience and knowledge in these areas contributing to this doc would be very helpful.
