Knoppix 5.3.1 DVD RAID5 Issue

[VladD]

I have an Intel G35 Motherboard, 4GB of RAM and 4 500GB HDD's configured (using "Intel Matrix Storage" features of the ICH9R) as a 1320GB RAID5 and a 103GB RAID0. I booted the Live DVD (5.3.1 EN) and the RAID0 is visible, while the RAID5 isn't. Here are some details:

knoppix@Knoppix:~$ ls /dev/mapper
control  isw_ciiagfcheb_Temp_Raid0

root@Knoppix:/ramdisk/home/knoppix# dmraid -s

So the RAID5 isn't accepted because "raid45" isn't there ... but there is a module called "raid456.ko" ... is it a typo somewhere?

As my old PC crached and I can't (yet) use my new one, my access to email is very limited. I'll check this forum from time to time, but right now I'm moving towards BartPE.

Are you under the mistaken impression that just because Linux has included software RAID drivers, it can somehow understand RAID structures created with proprietary Windows software RAID drivers that may use a different geometry?

[VladD]

Yes. Google-ing the subject gave me this "impression", as well as the fact that the RAID0 built with the same "proprietary" tools is properly recognized.

FYI, this RAID technology is not "Windows", but Intel, and if I'm not mistaken, the standard has been around since the beginning of this millenia. And, btw, it is the only decent solution a user without very deep pockets has to have both drive redundancy and multi-OS boot.
