To answer the question: It has to be so frustrating, because the OP wants to go the hard way and not stick to Linux system tools. That's IMO basically the reason.

Hi, Well, usually hardware raid is much better, at least if you want raid5/6, for raid 0 or 1 it is not such a big difference, but all of these on board raid chips are not hardware raid at all (fakeraid), you just have less influence/clue on what it's doing. The only reason to do this would be if you want to be able to read these partitions from windows. If you don't need this it's much better to just use the tried and trusted linux software raid, I did the same on my nforce4 board. It's quite easy actually, and you don't need an initrd at all.

Re: [gentoo-user] Re: Why ity has to be so frustrating !!!
He probably want's to use fakeraid because he wants to have a dual-boot Windows-Linux, both using raid. I also have had the same problem with 2.6.16 + dmraid, and the only solution I found was to use kernel 2.6.15-r9 (just 2.6.16). Only 2.6.15 gives me other problems...

Re: [gentoo-user] Re: Why ity has to be so frustrating !!!
Hi all on the list; thanks for attention. I need to use fake RAID because of windows ( I had incresed in 80% the performance of windows because of the fake raid :) ). I know linux software RAID is good, and I had already used on a box running just linux, but I really need to use dual boot on this box, and I don´t want to loose the performance of windows. I tryed to dmraid + 2.6.16 and all I got was that /dev/mapper/* was empty ( just have control node ). I had try 2.6.15-r1 and /de/mapper was populated but kernel panics when mounting root system, it says it can not find linuxrc and /bin/bash this is the situation, and is been like that for days. -- gentoo-user@gentoo.org mailing list
Re: [gentoo-user] Re: Why ity has to be so frustrating !!!
Hi I use a A8N-E, with nvidia raid controler 2 segate SATA disks working at RAID-0 ( sttriping ), I had installed gentoo base system and grub successfully, but at boot time with kernel 2.6.16 it cannot find device on /dev/mapper and with kernel 2.6.15-r1 it has a kernel panic saiyng it can´t find /linuxrc file and /bin/bash file. any more information needed ? just asks On 6/26/06, Francesco Talamona [EMAIL PROTECTED] wrote: On Monday 26 June 2006 11:58, James Buckley wrote: He probably want's to use fakeraid because he wants to have a dual-boot Windows-Linux, both using raid.

I have a 4 disks software raid (1 and 5 + LVM) setup. The motherboard has an integrated Promise controller that thinks the two disks attached are a single logical RAID0 disk. If I ever had a windoze on those disks it would run as if it was on a single striped disc, according to controller BIOS. While I was building this computer I also tested the software array phisically removing one of the striped discs, despite the dreadful error messages (the computer refuses to boot without an human intervention) at boot Linux booted flawlessly, just marking the array as corrupted. As I said before, to help OP we need more details about his setup. Side note: I use LILO. MB: Asus A8V-deluxe, no GRUB nor Nvidia here, so YMMV!.
