Problem Installing Arch on Raid0 Setup

Hey Guys,
I am trying to Install Arch (2008.06 X64 Core CD) on a RAID 0 setup, using the Fake-Raid Wiki.
The setup is a Nfroce 4 Motherboard, using the O/B Nvidia-Sata controller.
XP is already installed on the first part of the drive.

I started with this section:

# modprobe dm_mod sata_nv
# pacman -U /src/core/pkg/dmraid*
# dmraid -ay
# ls -la /dev/mapper/

The problem is that first command results in an Error: "could not insert module, unknown symbol or parameter"
I went on as ordered, ignoring the error and noticed that no mapper directory was created under /dev/.
So I am pretty much stuck at this point.

Help would be appreciated, thanks

Re: Problem Installing Arch on Raid0 Setup

There seems to be a problem in the latest kernel upgrade with the device-mapper setup.  Other posts refer to the problem as well.  My upgrade to Kde4 with lilo boot refers to the lack of device-mapper when running the /sbin/lilo -v command to initialize lilo.

It seems the 2.6.26 version of the package required is not recognized.

Re: Problem Installing Arch on Raid0 Setup

I take it there is a problem with current Kernel version...
And from the link you gave me, it is impossible to upgrade kernel into the installation as after installing it, you have to perform a restart, but then the update would be gone.

Do you suggest falling back to previous Version of Arch ? 2008.03 ?

I await new developments but a move back would be an option..................your choice.

Re: Problem Installing Arch on Raid0 Setup

Ok, a quick update.
Going back to 2008.03 solved the issue
I am back to windows as I have forgot to resize one of the partitions
Too bad cfdisk doesn't support that.

p.s.
waiting for a future version to solve this is not really a possible solution for me as I need to install Arch right now, who knows when this issue will be solved.
Thanks anyway for pointing this issue out.

Re: Problem Installing Arch on Raid0 Setup

OK, almost done.
I fail to chroot:
running "chroot /mnt/ /bin/bash/" gives me this error: "chroot: cannot run command '/bin/bash/' : no such file or directory"

After this it's the installation of GRUB which is the only thing I need to finish the installation.

any ideas what is wrong ?

Re: Problem Installing Arch on Raid0 Setup

Oh, it's a buggy build then as it seems
and the Device Mapper is broken?

I am completely new to Arch and was very disappointed that the installer couldn't even handle basic LVM tasks.
See my thread http://bbs.archlinux.org/viewtopic.php? … 02#p413602

Lucky I came across this thread, where you told that install from the 2008.03 image solved this for you.

So I will download this image too and give it another try.

Re: Problem Installing Arch on Raid0 Setup

You don't need to modprobe sata_nv, it will works without it. About chroot:

chroot /mnt/ /bin/bash/
You need to do:
chroot /mnt/ /bin/bash

Good Luck ;-)!

Re: Problem Installing Arch on Raid0 Setup

Please try modprobe dm-mod....this should open up device mapper in 2.6.26......................
