creating encrypted lvm partitions

gistfile1.txt

First, create an ext4 /boot partition (sda1), and an empty partition for encrypted LVM (sda2)

ubuntu-mate@ubuntu-mate:~$ sudo cryptsetup luksFormat /dev/sd
sda   sda1  sda2  sdb   sdb1  
ubuntu-mate@ubuntu-mate:~$ sudo cryptsetup luksFormat /dev/sda2

WARNING!
========
This will overwrite data on /dev/sda2 irrevocably.

Are you sure? (Type uppercase yes): YES
Enter passphrase: 
Verify passphrase: 
ubuntu-mate@ubuntu-mate:~$ sudo cryptsetup luksOpen /dev/sda2 crypto
Enter passphrase for /dev/sda2:
