Re: [opensuse] Root and boot partitions on a sw raid volume (opensuse 12.2 - 12.3 rc1 64bit)
I wasn't sure if I would be able to reproduce the issue or not, since a fake-raid on Linux seems to be treated similarly as a regular software RAID :)

Chris, as you're not using software RAID, I don't quite see what you want to test? -- Per Jessen, Zürich (3.2°C) http://www.dns24.ch/ - free DNS hosting, made in Switzerland. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
The primary differences between fake raid and pure software MD are
- fake raid is partitioned, software raid usually not
- fake raid is seen as single device by BIOS, software raid - as multiple devices
So they need different solutions. Fake raid is actually easier to handle. Pure software raid needs more work.

Hi, I also have problems with setting up a system booting from a md device. I have a system with 2 disks and installed OpenSuSE 12.3, downloaded 28 April 2013, Grub2 is used. I created 2 md devices /dev/md0 formatted ext4 for /boot, size 155MB and underlying partitons /dev/sdb1 and /dev/sdc1 /dev/md1 with LVM and VG rootvg (sorry I'm used to AIX) and all other filesystems, all formatted with ext4 Both md devices seems to be synced well during installation. mdadm -D /dev/md0 doesn't report any problems, both disk are in active sync. The system is able to boot from /dev/sdb device but fails to boot from /dev/sdc. I'm not sure if /dev/md0 is booted or /dev/sdb1. I tried several things to solve this issue like using dd to copy MBR partiton from /dev/sdb to /dev/sdc and grub2-install /dev/sdc to have grub2 installed on /dev/sdc When I try to boot from /dev/sdc the system starts the GRUB2 command prompt now but no further actions. Any idea how I can make GRUB2 work with /dev/sdc1? -- View this message in context: http://opensuse.14.x6.nabble.com/Root-and-boot-partitions-on-a-sw-raid-volum...

Hi,
I also have problems with setting up a system booting from a md device. I have a system with 2 disks and installed OpenSuSE 12.3, downloaded 28 April 2013, Grub2 is used.
I created 2 md devices /dev/md0 formatted ext4 for /boot, size 155MB and underlying partitons /dev/sdb1 and /dev/sdc1 /dev/md1 with LVM and VG rootvg (sorry I'm used to AIX) and all other filesystems, all formatted with ext4
Both md devices seems to be synced well during installation. mdadm -D /dev/md0 doesn't report any problems, both disk are in active sync.
The system is able to boot from /dev/sdb device but fails to boot from /dev/sdc. I'm not sure if /dev/md0 is booted or /dev/sdb1.

Please download bootinfoscript from https://github.com/arvidjaar/bootinfoscript and post output to http://susepaste.org/ (it may be relatively long). As long as you have enough space post MBR and core.img can be embedded "grub2-install /dev/sdc" should work. Copying MBR directly will not in this case (as it does not copy embedded core.img). -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org
