[opensuse] RAID1 boot problems
For years I've been setting up (open)suse machines with three (or more) partitions - each one using software RAID1, all partitions created and RAID set up during the installation. Has worked (at least up to 10.3) like a dream... /dev/md0 as /boot, /dev/md1 as /, and /dev/md2 as swap is(was) my current standard. Is it true that you simply can't do this (at least the /boot bit) with opensuse 11.x? I don't understand why this doesn't work, why this has changed in 11.x since it worked so well up to 10.3, and what I should be doing instead?

Good to know I'm not alone out there ! :)

I'd also like to know why this has changed !

If you really want to do it, install it as you always did but, on the Grub configuration change it to load on the the first Hard Drive MBR. The system will then boot but, only if that 1st HD exists... In order to circumvent it, also install grub on the other HD's MBR I'm also a bit frustrated with this Regression, if it is a regression at all.
Thanks,
jim

No, it works fine - with lilo at least. /Per -- Per Jessen, Zürich (4.68°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

I'm starting with two blank hard drives and the openSUSE-11.1-NET-x86_64 install CD. Please can someone give me a vaguely step-by-step process of how to achieve my "/dev/md0 as /boot, /dev/md1 as /, and /dev/md2 as swap", the configuration I've been using sucessfully for so many years with previous version of (open)suse.

Disclaimer - I don't use grub, and lilo is no longer supported in YaST, so some familiarity with lilo is probably needed. It's straight forward - I installed a system like that just the other day. I prefer creating the RAIDs ahead of time, it's faster and easier than using YaST, but it'll also work very well with YaST. Step-by-step - - boot your system from CD, select an installation source. - once you're in YaST, create your RAIDs, select mount points and go. - lilo installation will fail, but swap to a console and correct the /mnt/etc/lilo.conf file (comment out the line with message=), - chmod /mnt, rerun lilo - swap back, and you're done with stage1. /Per -- Per Jessen, Zürich (4.25°C) -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

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.

i am new to md and software-raid and have never used it before. i have a cleaninstall of opensuse 11.1 x86 and two sata disks sda and sdb, same size, same model. all attached to same sata controller. i have created sda1=2gig and sdb1=1gig for swap and rest of harddisk sda2 and rest of other disk too sdb2. all during install time. then created the raid1 stuff during the yast2 gui all during setup time while booting from the 11.1 install dvd. system booted up fine when using both disks. im trying raid1 (md0 = swap on sda1 and sdb1, md1=/ on sda2 and sdb2) with opensuse 11.1 how do i check these grub settings to verify if grub has been installed properly. do the above grub commands also apply to my setup, and when/where to i enter them? during runtime of my 11.1 system (runlevel3 runlevel5)? or do i need to boot from install dvd or runlevel1 or something? thanks for hints and explanations. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org

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.

I think you have either grub or BIOS issues. First if you are using any type of bios raid, check your BIOS and make sure you have your raid array set as bootable. (it can be hard to find, so check each bios page carefully). Next check grub. On 11.0 I have sda and sdb in RAID1 with /boot / and /home partitions.

I haven't unplugged a drive to check, but I would expect raid errors if the drives weren't mirrored: 12:43 ecstasy:~> sudo dmraid -r /dev/sdb: nvidia, "nvidia_fdaacfde", mirror, ok, 976773166 sectors, data@ 0 /dev/sda: nvidia, "nvidia_fdaacfde", mirror, ok, 976773166 sectors, data@ 0 No errors to date.

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...
