Hello, Thank you for your reply. Looks like you didn't get my point: Linux of course should see one hard drive but at capacity of combined two. If I set up HW raid0 of two 20GB identical IDE hard drives Linux should see just one big 40GB hard drive. In my case it sees one 20GB hard drive. So I'm wonder how to correct this issue. Thanks for any thoughts. Alex On Saturday 14 April 2001 04:17 am, you wrote:

Hello Linux folkz, I was trying to install SuSE 7.1 distro on ASUS A7V133 MB with Promise PDC20265 FastTrack100 onboard RAID controller. Surprisingly even though I configured raid0 of two WD 20GB HDs through the BIOS the Linux sees just one 10GB HD.

If i recall correctly, RAID0 is a hardware solution to create one large HD from different smaller ones.

So Linux is (of course!) correct. As far as the operating system sees it, you only have one HD.

Could somebody share his knowledge how to install Linux on HW configured raid array0.

Just use /dev/array0 as you normaly would have used /dev/hdc or /dev/sda.

Thank you in advance. Alex

I just looked up the raid levels:

RAID 0 - reads and writes are done in parallel for performance increase

In this case it still should be just a one 40GB hard drive (20GB + 20GB) not just 20GB.

RAID 1 - mirrors disks for redundancy and performance increase RAID 5 - build large disks and redundancy information

RAID1 and RAID 5 are not applicable in my case.

So, it looks like Linux is right (as usual <grin>).

In my case I doubt it. Regards. Alex

N.B. at RAID 5, the parity information is distributed between all the disks, so you have to substact the size of a disk from the total size.

It looks to me lvm - Logical Volume Manager - is more what you want. This creates a virtual disk and is a software sollution.

Regards, Cees.

Hello Keith, Thank you for your reply. Yes, please send me that Promise FastTrack100 driver or better tell where to get it. I'm going to use 2.4.2 kernel with this box. Definitely I need a driver for this darn chipset to be compiled into the kernel. Thank you in advance. Alex On Saturday 14 April 2001 09:18 am, Keith Gibbons wrote:

Alex, have you installed the Promise drivers, they need to be loaded in order to be able to see the extra drives. It is not enough just to configure the Fasttrak BIOS. I have tried unsuccessfully to get this card working with SuSE. Promise have supplied me with a driver for RH 7.0. I think it was compiled with kernel 2.2.16. I can forward it to you if you wish.
