- Load Mint Live DVD
- Setup RAID5 Array. Use gparted (or any paritition tool) to make /boot and root (/) and swap partitions on each drive. Then use mdadm to make RAID1 /boot, RAID5 root (/) and format swap partitions. (I don’t recommending RAID’ing swap spaces, or don’t make swap partitions at all, use a file based swap once the system is running)
- Run Installer – Do advance partition layout. Map /boot, /, and swaps (if swap partitions were made). Set boot loader to RAID1′s MD (It always fails for me. But we’ll fix it later)
- When installer is done, don’t leave live session. Open terminal. run the following
- mount /dev/md1 /mnt (md1 is my root mdadm array)
- mount /dev/md0 /mnt/boot (md0 is my raid1 boot mdadm array)
- for i in /dev /dev/pts /proc /sys /run; do sudo mount -B $i /mnt$i; done (Mount all special folders so we can run commands in a chroot environment. Taken from here)
- chroot /mnt
- apt-get install mdadm
- grub-install /dev/sda;grub-install /dev/sdb;grub-install /dev/sdc (This is installing grub on each drive, so if drive fails we can boot off another. do this for all drvies)
- update-grub
- exit
- reboot into os
