No, it works fine - with lilo at least.

If you use Grub, install openSUSE as you usually do, but instruct Grub to be installed on MBR. After the install process is complete, openSUSE WILL boot. However it only continue to do so only if /dev/sda exists. In order to correct it, do the following as root grub device (hd0) /dev/sda root (hd0,0) setup (hd0) device (hd0) /dev/sdb root (hd0,0) setup (hd0) After this you should be working as you've always been.

Thanks,

jim

I never used RAID until a couple of months ago, and spent a lot of time evaluating how I should do it beforehand. I chose mdraid because I have a long history of multibooting, and for mdraid it is not necessary to use whole disks as RAID devices. Long ago I learned need to repair was inevitable, and that repairs from HD boots were almost always easier than booting from removable media. So, I started by doing all my partitioning in advance of beginning installation anything. Next I booted a Knoppix CD, and installed Grub on hd0,0 and hd1,0. I then put OS/2 on hd0,1 and DOS on hd0,2, after which I installed 11.0, followed by 11.1. During 11.0 installation I created md0-md7 on hd0,6-hd0,13 and hd1,6-hd1,13. The details you can see on http://fm.no-ip.com/tmp/Linux/f965-02.txt . I directed the SUSE installers to put Grub on /, which failed in all cases, leading to: https://bugzilla.novell.com/show_bug.cgi?id=463033 Still, in spite of that bug, because I put Grub on hd0,0, I am able to boot both 11.0 and 11.1. Note that I do not mount hd0,0 as /boot in any case, so upgrades do not disturb what is working for booting. There's little significant benefit for a real /boot partition to live on RAID. Its contents infrequently needs to be changed. It if works that way, fine, but it is not necessary. I've never seen a benefit to putting Grub on MBR either. Usually it's just an opportunity for some installer to break an installation one wishes to keep intact. It usually isn't necessary, and I've never done it yet. http://en.opensuse.org/Bugs/grub#How_does_a_PC_boot_.2F_How_can_I_set_up_a_w... -- "Do not let any unwholesome talk come out of your mouths, but only what is helpful for building others up."

NO that is the way I run 11.0 and it runs fine.

Are you sure ? Are you using Grub ? Have you tried to unplug the first HD to see if it boots ? In my case, in all installs I did, the YaST system did not install itself on the second HD. -- Rui Santos http://www.ruisantos.com/ Veni, vidi, Linux! -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I haven't unplugged a drive to check, but I would expect raid errors if the drives weren't mirrored:

That is correct... The problem is that the MBR on the HD's are not mirrored. The Grub loader is copied only onto the MBR's first disk, and not the second. This will turn the system "unbootable" in case the first HD fails. However you use dm-raid... It may not apply to you...

No errors to date. A pull test will be a good experiment though. If it fails, I'll report back, but if I was a betting man, I'd bet it boots fine on either sda or sdb
