![]() ![]() Mkfs.ext4 -m 0 -L Backups /dev/mapper/b1 (-m 0 removes reserved blocks (i.e. set to 0%), since your system's livelihood does not depend on the empty space on this disk) 1 (to set it as the 1ST primary partition).p (to specify it as a PRIMARY partition).n (create a new partition table and a partition).Create the partition table (you know all your existing data on the disk will be gone, right?) To see the setup run lsblk.Įnough with theory. Partition table -> LUKS -> LVM -> partition tables. Then it sets up LVM on LUKS, by creating creates a physical volume, a volume group and two logical volumes, root and swap that contain the appropriate file systems. It creates the partition table, two unencrypted partitions (/boot and /boot/efi), one encrypted LUKS partition. The first way seems to be more compatible with the existing linux disk tools. An alternative is to have LUKS on the raw disk and then have partitions under it i.e LUKS -> MS-DOS partition table -> ext4. it will be like this: MS-DOS Partition table -> Luks -> ext4. As far as the disk layout goes, LUKS will be set up on a partion, then a file system will be created on LUKS. The idea is to use the main encrypted root partition to store the key for the backup disk.
