Prepare Disks

You have different choices to setup encryption. This chapter describes LVM on LUKS with encrypted boot partition. Because we want to unlock all volumes at once.

List your disks with lsblk and run gdisk /dev/[your disk] e.g. gdisk /dev/nvme0n1. You can take a look at the gdisk Arch Wiki en / de

It's crucial to use gdisk because GPT is needed for UEFI boot.

Please create 4 partition like described in the Arch Wiki above with gdisk. Use the codes for the partition type. Don't format the partitions at this time, we will do it later with the YubiKey. It should look similar like this.

Number  Start (sector)    End (sector)  Size       Code  Name
   1            2048            4095   1024.0 KiB  EF02  BIOS boot partition
   2            4096         1232895   600.0 MiB   EF00  EFI System
   3         1232896         2461695   600.0 MiB   8300  Linux filesystem
   4         2461696      2000409230   952.7 GiB   8E00  Linux LVM

The second partition contains the EFI System and must be of type FAT32. Format the second partition e.g. /dev/nvme0n1p2 with:

mkfs.fat -F32 /dev/[disk 2nd partition]

The next chapter describes how to prepare the YubiKey.
