ITE RAID/GigaRAID/LiveCD kernel

Hmmm, i was hoping for an easy clean install method with a livecd, but i haven't figured one out yet...

Maybe i need to move it to the raid array after the install

anyone got this to work with 2.6 kernel?

If so how?

cheers

HAHA, I was copying the scsi stuff to the same dir as the ITE source, make then copying the module to /lib/module/2.6.5/kernel/driver/scsi, then running an update-modules! Thanks for the instructions on how to do this correctly!

What kind of performance are you seeing in 2.6? I will try this driver this weekend and report results.

Woops, please disregard my post above! My ITE Raid had been not working for so long I disabled it in the BIOS. After enabling it the module loads just fine.

Thanks to all the people who posted helpful information in this thread

http://68.106.153.174/patch-linux-2.6-iteraid-1.43.bz2

Someone emailed me this patch and asked that I post it. I do not know this person, so you might want to check the patch before you apply it. THanks:

Hi,

I was visiting the gentoo.org forums and noticed in one of the ITE
threads your comments about the patch for 2.6.x kernel.

I have created a patch for 2.6.4 kernel which should work with older and
newer 2.6.x kernels.

The patch can be compiled in the kernel (Y) or as loadable module (M).

To enable it go to SCSI --> Low Level Drives --> SATA / ITE driver.

I am not a registered user to gentoo forums so you could post the diff
to the ITE thread for other users of GIGAByte mainboards that would like
such support for their RAIDs.

Hope this helps.

Regards,

Paul B.[url][/url]

WooWooWoo,
it was all running real smothly up to now, but...
I have 2xIDE as RAID1 and a S-ATA Harddisk.
I did a basic installation on the SATA (hde in my case), compiled the drivers, booted into that installation, loaded the modul and started partitioning the RAID that showed up as sda.
Fine up to now, but after starting with a Stage1 installation on the RAID last night and decided to continue today. So shutdown worked fine, but when I rebooted the machine I cannot boot into my basic installation on hde anymore.
CD booted and reinstalled GRUB but nope.
I can disable the HWRAID in the BIOS and boot into my basic installation, but then, I cannot access my RAID (because it is disabled and loading the module causes the kernel to crash).
So,
I have no idea how to get in my basic install with RAID enabled as it won't boot.
I am kinda scared right now...
HELP...

Okay, after loosing my first PANIC-ATTACK, I remembered some good old friend of mine I haven't seen for a looong time: BootFloppy
with Grub did the job.
Installation got me back.

Hi guys & girls,

I have the same (ITE) RAID controller on a 8KNXP Ultra mainboard. I did the following to get it to work :

- Installed Gentoo with one HD connected to the normal IDE controller (hdc)
- Compiled 2.6.4 kernel with ITE support using the nice patch mentioned in this thread.
- Created a bootdisk using this kernel
- Moved harddisk back to RAID controller (becomes sda)
- Booted using bootdisk with root=/dev/sda3 (3 = root)
- Updated fstab, rebooted, everything fine.

So the current setup is one HDD connected and working on the RAID controller. The problem is that when I add (connect) the second HDD (which is currently still empty), Linux won't boot anymore. I get lots of 'ITE: resetting' messages during boot, and it just doesn't get any further. I am a bit confused about how to set this thing up. Do I need to define a RAID configuration in the GigaRaid BIOS ? (Currently none is defined because I thought that the Linux software raid will take care of that instead). How can I get my machine to boot again using both drives connected ? Do I have to make changes in my mainboard bios ?

Please help me out here

Thanks !

rig0r,

Yes, you definately need to configure your raid array in the gigaraid bios! After that, the kernel doesn't even know it's raid or not. If you just connected the HD to the controller and didn't do any configuring, you are probably just using the disk like any other disk. You'll at least need to specify what type of raid you want in the bios...

Problem might be for you that setting up the raid array will probably erase your current disks...

Bye,

Hmm are you sure my disks will be erased when creating a new RAID array ? Must be some way to get around this I hope

nope2dope · Posted: Thu Mar 25, 2004 1:08 pm Post subject:

It is not for sure that your disks will be erased, but it can happen.
I personally think it is pretty save to set up a RAID1 afterwards, but don't blame me neither.
There is something like a rebuild RAID option in your RAID setup.
Got no idea about the RAID0.

Ok, I will give it a shot tonight. Worst thing that can happen will be a reinstall

However I have a small question about that. I currently have a 2.6.4 based bootdisk, which I created using my current gentoo installation. It has support for the ITE raid controller and some other stuff. I will need this kernel/bootdisk to do a reinstall. Is it possible to use this bootdisk and then somehow mount the LiveCD ? Or is there a way to get my custom kernel on a LiveCD ? I have looked through the forums but can't really find posts that match this particular case.

Thanks again !

Does anybody know what kernel options I need to enable to build the 2.4.24-xfs-r3 kernel exactly the same as what's on the Gentoo 2004.0 CD-ROM so I can stop getting these unresolved symbol errors when I try to insmod -f iteraid.o?

carpman · Posted: Fri Mar 26, 2004 9:59 am Post subject:

rig0r · n00b Joined: 25 Mar 2004 Posts: 73

Having the same problem here when doing insmod -f iteraid.o :

iteraid.o: unresolved symbol register_chrdev_Rblabla
iteraid.o: unresolved symbol mem_map_Rblabla
iteraid.o: unresolved symbol scsi_unregister_Rblabla
iteraid.o: unresolved symbol scsi_register_Rblabla

This module was compiled on another gentoo system with exact the same kernel version and kernel options as on the LiveCD.

The CRC option mentioned above doesn't help a bit here.

Any clues ?

Maybe someone can send me an iteraid.o that actually works with the Gentoo 2004.0 LiveCD ? (rig0r@hotmail.com)

IvanHoe · l33t Joined: 05 Oct 2002 Posts: 658

I solved it by using the genkernel utility to build the kernel.

rig0r · n00b Joined: 25 Mar 2004 Posts: 73

That's good news

But can you be a bit more specific at how you did this using genkernel ?
