 Posted: Fri Jul 06, 2007 5:21 pm Post subject: [Solved] Installing Gentoo on RAID0 ICH8 (Intel Matrix RAID) |
 |
|
Sorry for my stupid question, but i am total noob in Linux, so i can't assemble answer from pieces of information spread allover this forum
My hardware configuration:
Gigabyte GA-965P-DQ6 (rev 1.0)
Intel Core 2 Duo E6600
ATI Radeon X1900
2*Seagate 7200.10 ST3320620AS 320GB (connected to ICH8R SATAII ports 0 and 1)
I made intel matrix RAID with RAID0 (Volume0) and RAID1 (Volume1) volumes, after it i partitioned Volume0 and set up Windows XP x64.
I left 30GB for Gentoo unformatted partition in oreder to partition it during the installation.
Now I'm trying to install Gentoo from 2007.0 Live CD
I read this howto, but didn't understand a thing there
As i know, i don't need to create special small boot partition, do i?
After X failes (no drivers) Gentoo offers me to run dialogue-based installer
Should i run it immediately with any parameters (i don't understand how to use dodmraid) or should i do some actions before, because installer doesn't see my raid volumes, only physical hard drives
I'm dreadfully sorry to ask, but could you write a short step-by-step guide for me how to make Gentoo see my RAID volumes.

| You should create your partitions before trying to run the installer. From a root terminal, try running dmraid -a y and see if your devices show up in /dev/mapper/. If you, you can run cfdisk or whatever on the main device to partition it. I've never tried matrix raid so I'm not sure how it'll handle it. If your devices don't show up you may be SOL. |

as for Windows OS matrix RAID is no difference to to RAID0 if it helps.
ok, i'll try it, thanx
i tried.
i boot gentoo
then after X fails to boot if i input dmraid -a i get
bash: dmraid: command not found
in dev/mapper there's only control
if i try booting like gentoo dodmraid the same story, but in dev/mapper ls returns
control
isw_chcbiehcba_Volume0
isw_chcbiehcba_Volume01
isw_chcbiehcba_Volume05
isw_chcbiehcba_Volume06
isw_chcbiehcba_Volume07
isw_chcbiehcba_Volume1
isw_chcbiehcba_Volume11 |

Can you use cfdisk on /dev/mapper/isw_chcbiehcba_Volume0 or 1?
You should be able to create partitions and such with those. |

yes, cfdisk works perfectly
i've created partitions for /,home and a swap partition
and i can see my ntfs partitions both on RAID0 and RAID1
the only thing is that intaller doesn't see my RAID, only two separate HDDs |

That leaves me to believe that your raid controller isn't really a raid controller but a fake-raid thingy.
This is very common for controllers integrated into the motherboard. These "raid" controllers rely on custom drivers to make the operating system the drivers are for (ie. windows) think that you've got a real raid disk when in fact it's more than 50% software raid.
Support for such fake-raid controllers in linux is sparse. There are some proprietary drivers availible but these (i hear) are buggy and not supported.
Since these fake-raid systems (unlike linux software raid) require entire disks to be committed to the raid you cannot raid only parts of your disks.
You now have got a couple possible paths to choose from:
A) Don't use raid at all
B) Get a 3rd (and perhaps a 4th) disk for linux and run linux' software raid for linux stuff.
C) Drop the raid for windows and use the two disks as regular disks in windows and set up software raid for linux
I am currenty facing the same problem with my 3-disk setup. I was looking for a way to put / on a software raid set when I stumbled across your problem.
It looks that I am going to go for option C myself.
I hope that helps.

| His device is supported (yes it is software raid, as pretty much any onboard raid is.) The problem is that the gentoo installer doesn't recognize the devices as disks. You can either do an old fashioned manual install, or install to a third disk and copy things over. Either of these steps will require quite a bit of knowledge of how your system works. |

OK. I finally did it. It took a large amount of beer and efforts to understand my mistake.
I manually configured kernel, and and installed grub, but kernel didn't load because device-mapper was included like module. Then i emerged genkernel and now it works pretty nice. The only thing that is to do - compare genkernel config and my own to find mistakes
Thanks a lot to HeissFuss |
