HOWTO - Discovering and using existing sata raid (eg sil3112)

[[_Silence_]]

Sorry for dragging this thread up, but it seemed appropriate

I followed the how-to given at the start of this thread, and all went well. almost.
I can see my raid array in GParted fine and correct, but when i try to run the "activateraid" scrip i get this:

INFO: Activating stripe RAID set "sil_afaddgceajabb"
INFO: Activating partition RAID set "sil_afaddgceajabb1"
INFO: Activating partition RAID set "sil_afaddgceajabb5"
mount: special device dev/mapper/sil_afaddgceajabb1 does not exist

But it does exist! I've seen it!

Help? Please?

I have the exactly same problem, running 2x 160Gb SATA in Raid0, NForce4 controller, but using Ubuntu 5.0.4.
Anyone know why it says that?

Just had to register to say thankyou for this great guide..

After trying various linux distros over the last year I never managed to get to access my sata raid 0.

Now after an hour, mostly down to typo's on my behalf I can access my NTFS SATA partition!!!!

I too signed up just to say 'thank you'

THANK YOU

All I had to do was run dmraid -ay and life is good! Thanx a bunch!

I have two 160gb sata drives in a raid 0 with ntfs on them. I have it set up to mou tnat boot time. Thank you for such a good guide. I run slackware, so it was a good thing this guide is distro independant. Any 2.6 variety of kernel has device-mapper support in it.

Thanks again, -Bill

Thanks for the howto.

Managed to get my striped set (RAID0) working following this howto.

2 x Seagate SATA disks on an VIA VT6420 controller (ASUS A8V Deluxe motherboard).

Hello,

Could you please provide more details?

I'm using WinXP now, with 2 160Gb HDD in RAID0. I left 40Gb Partition Free to install Ubuntu, but as some of you, ubuntu installer recognize 2 160Gb HDD instead 1 RAID set. My Mobo is ASUS A7N8X-E Deluxe with Sil3112 Controller.

Even last ubuntu beta has same behavior on installer.

About the description to install kernel, it seems how to install from Linux, but, could you provide more details about how it is done since boot?

How did you boot the system to install new kernel? By LiveCD? Floppy Disk?

I cannot find any good description over the internet.
Several people says that is better install Linux Raid instead Sil3112 Raids, but I already has installed, and worried to lost my WinXp data.

Any help will be welcom.

still no go for ATA RAID ?

i have HPT372 on a DFI Lanparty mobo,
with 2x 120 GB attached, i even managed to get windows installed on it ,
but i can't figure it out on ubuntu 5.04 (didn't try another distribution for that purpose, yet) ...

all i get after following the steps is also an empty
/dev/mapper/control

maybe some mind get us some help with the opensource driver they provide ?
http://www.highpoint-tech.com/BIOS%2...ource-v2.0.tgz

i'm used to osx, and a very little to debian, but this is all completely new to me,
and, besides, giving me a headache


any help greatly appreciated,
thanks in advance

ERROR: sil: setting up RAID device /dev/sdd
ERROR: sil: zero sectors on /dev/sde

Regarding the subject...

I installed Mandriva 2006 Beta in existing RAID0 as described before,
without any problem!!

Just insert CD and that's all!

Ubuntu guys should investigate about this procedure....

Don't copy exactly the line in the first post

mount -t <fs type> -o users,owner,ro,umask=000 dev/mapper/<your partiton name> /<your mount dir>

because there is a little error...
Try

mount -t <fs type> -o users,owner,ro,umask=000 /dev/mapper/<your partiton name> /<your mount dir>

with the "/" before dev...
