The idea is to have two harddrives in mirror mode with complete system encryption. For each harddrive we need a BIOS boot partition with grub core.img stuff in them. They have to be configured and installed (in grub) in such a way that each harddrive can boot from itself. I have decided to have the swap partitions not in any RAID configuration. Each harddrive will have a separated swap partition, each swap will be encrypted with a random key. The rest of the disk is the whole linux system (including /boot). This is going to be a RAID1 (copy) with a LVM on top (to allow future extension) and encryption on top.

• Create GPT partition table with gdisk
• Create a BIOS boot partition of 1MB (necessary for grub2 on GPT disks)
• Create a swap partition
