Question dmraid - installing to a raid array?


I have just built a new 64bit system (amd) with raid onboard the motherboard - nf4. I want to install slamd64, the 64bit port of slackware. the problem i am up against is that i want to install it to my raid array (raid 0 - 500Gb). I have read up on using raid in linux at this site <url>Http://</url> the only thing is i want to install to this array (from the start) obviously the cd image i have of slamd64 doesnt contain the dmraid software. Anyone got any ideas on how i can do this?
p.s i already have to ntfs partitions on that array

same thing


Exact same question. How do I get dmraid to load with the installer in slamd64 (two SATA disks as well)?

Realizing this is probably something that is rather simple to figure out... it's still easier to have you fine fellows tell me how to do it rather than try and do it myself (where would the world be if we did that? I'd be out of a job!)

I just managed to get a VIA 8237 fakeraid mirror set up. It all works beautifully. The only pain is that the original disk devices and partitions in /dev are still visible. I need to work that out...

for the interested, some steps:

1. I first installed Linux (Mepis) onto one of the SATA disks, with the other disk disconnected.
2. I then shutdown the PC and connected the mirror disk. When booting, the controller discovered the extra disk, and gave me the option to rebuild the mirror set. This takes some while!
3. After lots of looking around, I stumbled across this page: It describes how to setup a striped (raid 0) set, but it contains a link to a page that gives the setup for raid 1
4. I edited /boot/grub/ and /boot/grub/menu.lst. They now look like this:
(hd0) /dev/hda (my IDE disk)
(hd1) /dev/mapper/via_ddcafcgade (the DMraid created device in /dev/mapper)

title MEPIS mirror disk
kernel /boot/vmlinuz-2.6.15-1-586tsc root=/dev/mapper/via_ddcafcgade3 nomce quiet
initrd /boot/ (this is the initrd image I created, which loads dmraid)

Basically, that's it!

Now, if someone knows a way to get those old devices out of the list, that'd be great...
