Darryl,
Thanks for your help.
So a step-by-step howto should be something like:
1. Install Debian on HD "A"
2. Load md and raid1 modules ("modprobe raid1 etc...")
3. Add both modules in /etc/modules
4. Install "mdadm"
5. Zero array devices ("mdadm --zero-superblock /dev/hdX")
6. Partition HD "B" and "C" ("cfdisk /dev/hdX")
7. Create RAID ("mdadm -Cv /dev/md0 -l1 -n2 /dev/hdB /dev/hdC")
8. Format array ("mkfs.ext3 -j /dev/md0")
9. Mount array ("mount /dev/md0 /mnt/array")
10. Insert line "/dev/md0 /mnt/array ext3 defaults 0 0" in "/etc/fstab" file
11. Set automatic array startup ("dpkg-reconfigure mdadm")
12. reboot
Is this OK ??
TIA
K.
