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...
