cryptsetup --verbose --verify-passphrase luksFormat  /dev/mapper/<lvname>
  • You will be asked for password
  • Create mapping between logial volume and luks partion
cryptsetup luksOpen /dev/mapper/<lvname> crypthome
  • You will be asked for password
  • create /etc/crypttab file with following contents (replace <lvname> with name of you logical volume reserved for “home”):
crypthome /dev/mapper/<lvname>
  • format crypthome 
mkfs.ext3 /dev/mapper/crypthome
  • edit fstab and replace <lvname> with crypthome
  • test if you can mount partition
