HOWTO: SUSE 10.0 and Software RAID a.k.a FakeRAID

[markes]

I got that message linux-r1rn:/home/mk # dmraid -ay -i
ERROR: dos: reading /dev/mapper/via_bdeaacdjjh[No such file or directory] ,too. But this was because of an old dmraid version. With the new version of dmraid-1.0.0rc11-pre1.tar.bz2 i still have no problems.

/var/log/messages:
May 21 07:44:32 linux-r1rn kernel: device-mapper: dm-stripe: Target length not divisible by chunk size
May 21 07:44:32 linux-r1rn kernel: device-mapper: error adding target to table

Hello,
thanks to crushton, markes and maaki (from www.linux-club.de) finally i just managed to install Suse Linux 10.1 on my FakeRAID! Because i had some problems with the ways provided here i wrote another guide (german language only) how i did it.

Hmm,

From a fresh install, can't you setup RAID 1 from there? In setting up the initial system partitions, can't you set it so that /boot is mounted on a normal partition and format two identical partitions on two separate HDDs as Linux RAID and using the RAID utility thereafter? Atleast that's what I did...

Like splitting the RAID 1, installing and setting up (incl. dmraid) Linux to the first (primary) HDD and finally rebuilding the mirrored RAID 1?

For RAID 1 that is probably true, but you can not do that with RAID 0. For me it was much faster to install Linux to a seperate HDD, because i already had one extra HDD built-in and i did not have to rebuild my RAID.

Sincerely yours,

This is the first time I installed Linux on this Intel ICH9R sofRAID system, but need updated version of this howto. If anybody has one for openSUSE 11.1 please share with us.

One more question is: what line of /etc/mkinitrd on a runnning Linux should I put the "dmraid" script to have openSUSE recognize my Vista Device Mapper at boot time?

I have a strange situation that I can only boot with floppy but also disk order changes on the fly. GRUB knows disk order at boot time but OS changes all disks to non-raid. I put dmraid -ay in /etc/init.d/boot.local to access Vista.

I have fair amount of knowledge with Linux but I'm not good with programming logics. Please reply, this is my first post in this list.

thanks in advance
