Currently, I'm running SuSE 7.3. I want to do an upgrade (not a new install) to 8.0. This seems to be impossible if the root partition is a RAID device (software raid, with persistent superblock, automatically recognized by the kernel). The thing that drives me crazy is that my RAID _is_ recognized during boot from CD1. However, if I choose "upgrade of an existing installation", when it comes to mounting the root partition, it insists that /dev/sda3 holds my root partition, in stead of /dev/md0. What can I do to make /dev/md0 to be recognized as my root partition? Any hint would be greatly appreciated. Below some more information, to show my current setup. # mount /dev/md0 on / type ext3 (rw) /dev/sda3 on /boot type ext2 (ro) # cat /proc/mdstat Personalities : [raid0] read_ahead 1024 sectors md0 : active raid0 sdd2[3] sdc2[2] sdb2[1] sda2[0] 15679104 blocks 32k chunks -- Paul.
