    Mdadm and moving distros

    ok here we go, I have decided to change distros from FC10 x86_64 to open suse x86_64. I happen to have a spare hd to test the move first (thank god) I installed open suse on it, updated everything, plug up my sata drives, power up, goto terminal, su, mdadm -A /dev/md0 /dev/sd[abcd]1 and it says cant find superblock. Boot back to fc 10 goto terminal, su, mdadm -A /dev/md0 /dev/sd[bcde]1 (the show diff drives in fc) and it works fine. Ideas ? trying not to lose 500 gigs of raid 5 data on 4 500g drives

    ** Note the section on restoring an md RAID set and its config file => /etc/mdadm.conf


    1. Boot into FC10, save your mdadm.conf for reference, and save info from

    cat /proc/mdstat
    mdadm --misc --detail /dev/md[X]
    2. In SuSE, make sure fdisk -l shows your disks and that you're using the correct /dev/sd[X] reference.
    3. Copy/build the mdadm.conf in SuSE
