setting up raid autodetect for boot?


I plan to move my /home and /var/www directories over to two raid mirrors I have, and the mirrors are set up perfectly, except for the fact that I can't seem to figure out how to set up raid autodetect

I'm using kernel 2.6.8

http://www.tldp.org/HOWTO/Software-RAID-HOWTO-7.html

^^ That link defines 3 steps at the beginning of section 7.2, and it'd be great if someone could take me into greater detail on step 1, and also checking step 2 and making changes if necessary. I think step 2 is fine, but step 1 is where i'm having issues, and they go into no detail on that page.

for starters, can someone help me out with:
1) do the kernel images from the apt repositories have/support autodetection?
2) if not, what do i need to do to obtain it? maybe just add a module(s)?
3) if the kernels already support autodetection, then what else do i need to do to get these raid arrays detected on boot?


add any other supplemental/additional information you think would be helpful or overall good to know.

I've been messing with this and googling for a while, but I can't find critical details that should probably come from someone who has set this up before

Hi FilesLikeABrick,

did you get some light behind your question? If yes... can you share, please?
I try to set up a sonftware RAID and can't figure out, how this autodetection thing works...

I have persistent super-blocks installed, and the partition types are set to 0xfd, too.
If the howto is right, there must be something with the kernel autodetection...

I use debian sarge with kernel 2.6.8.

Thank you very much,
Clemente
