To configure encryption on an empty LVM logical volume in Ubuntu 22.04 (Also works on Ubuntu 24.04) after OS installation, follow these steps:
Encrypting and Mounting a Logical Volume with LUKS
- If the logical volume is already mounted, unmount it:
# sudo umount <mount-point>
Format the Volume with LUKS Encryption
Use `cryptsetup` to encrypt the logical volume:
# sudo cryptsetup luksFormat <lvm-path>
Open the Encrypted Volume
Open the LUKS volume and map it to a device name (e.g., `data_crypt`):
# sudo cryptsetup open <lvm-path> data_crypt
