problems installing grub on ICH6 fakeRAID

hey there!

I'm currently installing arch on my "new" computer. It's mainboard has an Intel ICH6R controller and I want to use its RAID functionality.
I'm following the FakeRAID wiki article for the setup, and I'm stuck at the grub setup part.

grub> device (hd0) /dev/mapper/isw_cchbiijfii_RAID_Volume0

grub> geometry (hd0) 9001 255 63
drive 0x80: C/H/S = 9001/255/63, The number of sectors = 144601065, /dev/mapper/isw_cchbiijfii_RAID_Volume0
   Partition num: 0,  Filesystem type unknown, partition type 0x7
   Partition num: 1,  Filesystem type is ext2fs, partition type 0x83

grub> root (hd0,1)
 Filesystem type is ext2fs, partition type 0x83

grub> setup (hd0)
 Checking if "/boot/grub/stage1" exists... yes
 Checking if "/boot/grub/stage2" exists... yes
 Checking if "/boot/grub/e2fs_stage1_5" exists... yes
 Running "embed /boot/grub/e2fs_stage1_5 (hd0)"...  19 sectors are embedded.
succeeded
 Running "install /boot/grub/stage1 (hd0) (hd0)1+19 p (hd0,1)/boot/grub/stage2 /boot/grub/menu.lst"... failed

Error 22: No such partition

as you can see, the array and the root partition is being found properly. I just have no idea why the "instal ...." thing fails.

and here is the partition table:

[root@archiso ~]# fdisk -l /dev/mapper/isw_cchbiijfii_RAID_Volume0

Disk /dev/mapper/isw_cchbiijfii_RAID_Volume0: 74.0 GB, 74038116352 bytes
255 heads, 63 sectors/track, 9001 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0xbf9bbf9b

                                   Device Boot      Start         End      Blocks   Id  System
/dev/mapper/isw_cchbiijfii_RAID_Volume0p1   *           1        5099    40957686    7  HPFS/NTFS
/dev/mapper/isw_cchbiijfii_RAID_Volume0p2            5100        9001    31342815   83  Linux

(the first partition contains some other OS, which is the reason why I can't use software RAID)

I've no idea what to do. Hope someone can help me there.

Greetings, Jake

Re: problems installing grub on ICH6 fakeRAID

Hey,

I had the same problem recently when installing Windows and trying to reinstall grub.  Oddly enough, it didn't work using the latest ISO (2009-08) but it did work with an older one, the one I installed it with for the first time. I'm not sure which ISO it is, I can check if you still have the problem. As for the installation: I pretty much followed the FakeRAID wiki too (mounting my installation + chroot + the grub commands you posted) and simply by using the older CD it worked. Maybe it's something about the dmraid or grub version.

It's a know bug... dmraid and 2009.08 doesn't work ok. Setup your system with 2009.08 and install grub with 2009.02. Works for me...

Install grub with 2009.02? How exactly? You just the last part of the grub installation is to use the 2009.02 CD?

Re: problems installing grub on ICH6 fakeRAID

TigTex is right. Do the installation until the grub install part from 2009.8, reboot from 2009.2, and do the grub installation from then on. That is what I did.

In fact you can still use the 2009.2 for the full installation process. When finished (assuming you have the right internet connection and bandwith) pacman -Syu , and your arch will be brand new. This is not the bulky Fedora fettuhi, new iso releases only make the installation easier. Below is how I did it using 2009.2 at the time:

If I am wrong, somebody correct me.
