Linux software raid can say, "ok, use sda1, sdb1, sdc1, sdd1 as raid1; sda2, sdb2, sdc2 as RAID-5 with sdd2 as a hot spare; and finally, sda3, sdb3, sdc3, and sdd3 as raid0".

Install grub to the MBR of both those drives. Or just make it a plain partition. If you use raid0 at all, reliability is obviously not an issue for the system overall, and performance for /boot is not an issue either so a plain single partition on the first drive is fine.

Because linux has better software raid than the bios. And it is not tied to specific hardware/bios versions, but can be moved between systems quite easily.

I am surprised if the amd64 3.1 doesn't see the network byt i386 3.1 does. They should support the same hardware. There are some detection issues with nvidia ethernet in amd64 3.1, but usually doing 'modprobe forcedeth' on console 2 and going back to the installer fixes that.

Using raid1 for /boot and raid0 for everything else would simplify things, I hope. Having said that, I've not actually used raid for booting off myself, I've just had to debug GRUB-not-booting-again problems several times :| > I followed the instructions outlined at > http://www.howtoforge.com/linux_software_raid?from=10&comments_per_page=10 > and got further than ever before, but couldn't successfully install > either GRUB or LILO. > > The article above suggests 4 raid partitions >/boot (50M) >/swap (1G) >/ (10G) >/var (the rest) > > It is also written specifically for RAID1, though it implies that > doing the same for RAID0 would work.

Regardless, I've tried it three ways: If you're using md within partitions the MBRs are exempt, because they're outside all partitions. But when booting, grub will load most of itself from the /boot filesystem, wherever that is. It will embed part of itself in some "empty space" at the head of the filesystem (as I understand it) and the remainder will be loaded by navigating the filesystem itself. The code to load the embedded bit is very simplistic, and doesn't appreciate the difference between sda1 and md0. > >case 1: /boot as a specific 50M partition, on the 1st SATA drive > (ext3) >case 2: /boot as a RAID1 collection of the first 50M worth of all 4 > SATA drives (ext3). >case 3: /boot as a RAID0 collection of the first 50M worth of all 4 > SATA drives (ext3). >note: In all 3 cases, the remainder of the drive was configured as > a RAID0 array, and I used LVM (1 volume group) to created two logical > volumes, a 4G swap volume and the rest (to mount as /). > > case 1: allowed me to complete installation, grub appeared to install > okay, but it doesn't boot, I just get a blank screen. Very odd-- so you never get any of the "stage1 loading..." messages or anything? This really should have worked. Or did the screen go blank as it was booting and then not unblank? (Just as a matter of interest-- does installing without raid work at all? How about using the installer as a rescue disk, does that work?) > case 2: the partitioner seemed to change the partition types, and > would never let me install GRUB. Ick. Presumably the partition types got changed to the "raid autorun" type to be used by the kernel's own md bootstrapping code. If you have sda1 and sda2 as md0 (raid1) then you should be able to install grub to sda1 directly. However, persuading it to do this from inside Linux is convoluted-- you have to rewrite the device.map to specify that (hd0) is sda, which is presumably the reason for the installer not doing this for you. An alternative approach is to make a grub floppy[1], boot that, and then setup grub from there-- just do "root (hd0,0)" and "setup (hd0)". You need to have grub "installed" as in the files need to be in /boot/grub/ for the setup command to work. Presumably you won't have a useful menu.lst file, so you'll have boot the system "by hand" at least the first time-- after "root (hd0,0)" you need to do "initrd /initrd.img-whatever" and "kernel /vmlinuz-whatever root=/dev/md0" and then "boot". Not sure what parameters you may need to give to the kernel to get md0 automatically assembled-- "md=autorun"? Istr it days gone by there was a "build a boot floppy" option. Has that gone now? [1] which you can do with just dd from the shell while installing. A grub boot floppy is a terribly useful thing to keep around btw. From memory: "dd if=/boot/grub/stage1 of=/dev/fd0 bs=512" and then "dd if=/boot/grub/stage2 of=/dev/fd0 bs=512 seek=1".

In subsequent research (including this list archive) it appears that the BIOS RAID is considered 'inferior' to the software RAID support in Linux. So, my questions are: 1) Why is the ASUS BIOS RAID inferior to software RAID on Linux? Not necessarily inferior, but _unnecessary_. As others have pointed out, this is not a real raid controller. The bios does software raid, and the windows driver for the card does software raid for windows (if you use windows at all, that is.) The fact that you _need_ a raid driver in window is a strong hint that the raid is implemented in software - a hw raid controller can be made to look like a single disk on a standard controller - both linux and windows can then handle it without special drivers. So, in order to use a raid with this controller you need a software driver for it. And one exist - the linux software raid (md). It offers raid 0+1, among other things. You can get more space from your 4 disks with raid-5, but raid 0+1 will probably have better performance if you get the stripe size right. Note that bios raid and linux sw raid isn't compatible, so you have to turn bios raid off in order to use linux sw raid. There is no loss involved in doing this though. 2) Is it possible to install 31r1a instead of the Etch release (I'm not overly keen on working with Etch, but will do it if it's a better 64-bit option...In the few days I played with 64-bit Etch it seemed to work well, but I didn't have most of the utilties I need available from the installer/package manager). 3) Do I need to flash the BIOS for things to work? No - linux doesn't use the bios. The bios is only used to set up some hardware at power-on time, and to load the linux kernel which then takes over everything with its own drivers. Flashing the bios is sometimes useful if the old bios has bugs. Or if you want to do something radical like running linuxbios. 4) Is ATI 300 support better in Etch? I haven't tried, but I have the impression that unstable/experimental have more and better support for 3D. But of course there are more bugs to stumble over as well. You may want to try xserver-xorg 6.9.0.dfsg.1-4. (Also upgrade all the accompagnying libx... packages, xserver-common, libdrm and mesa packages.

So you unless you use a software to control it Linux is not going to see it. See these threads for details: http://www.nvnews.net/vbulletin/showthread.php?t=57548 http://www.nvnews.net/vbulletin/showthread.php?p=661719#post661719 Quote from: http://gentoo-wiki.com/HOWTO_Install_Gentoo_with_NVRAID_using_dmraid "The NVRAID BIOS is actually a software raid. The method used to install here will work with other operating systems such as Windows with no configuration changes needed with Windows. In linux 2.4 the Ataraid kernel framework provided support for software RAID assisted by the BIOS. For kernel 2.6 the device-mapper runtime can do the same kind of work, but it's configured in userspace however. Heinz Maulshagen introduced the dmraid tool to create RAID mappings using the kernel device-mapper subsystem. The controllers supported are (mostly cheap) Fake-RAID IDE / SATA controllers which have BIOS functions on it. Most common ones are: Promise Fasttrack controllers as well as HPT 37x, Intel and LSI. Also serial ata RAID controllers like Silicon Image Medley and Nvidia Nforce are supported by the program."
