Format the EFI system partition and label it (replace /dev/sda1 accordingly):

mkfs.fat -F 32 /dev/sda1
fatlabel /dev/sda1 EFI

Format the LUKS partition and label it (replace /dev/sda2 accordingly):

cryptsetup luksFormat /dev/sda2
cryptsetup config /dev/sda2 --label "LUKS"

Check the results with

cryptsetup luksDump /dev/sda2
lsblk -f

Open the LUKS partition:

cryptsetup open /dev/sda2 root

Format and label the mapper device:

mkfs.btrfs -L LINUX /dev/mapper/root
