    Is the Linux OS drive fully encrypted or can i do more?


    when i do "sudo lsblk" on Ubuntu 16.04.3 LTS
    cryptsetup 1.6.6, i see:

    NAME                     MAJ:MIN RM   SIZE RO TYPE  MOUNTPOINT
    sda                        8:0    0  37,3G  0 disk  
    ├─sda1                     8:1    0   487M  0 part  /boot
    ├─sda2                     8:2    0     1K  0 part  
    └─sda5                     8:5    0  36,8G  0 part  
      └─sda5_crypt           252:0    0  36,8G  0 crypt 
        ├─lubuntu--vg-root   252:1    0  34,8G  0 lvm   /
        └─lubuntu--vg-swap_1 252:2    0     2G  0 lvm   
          └─cryptswap1       252:3    0     2G  0 crypt [SWAP]
    During installation, i tried to tick the encryption option with hope it will be "full disk encryption". Was it successful or what can i do more so all data are encrypted? Thank You

    I can be found either 40 miles west of Chicago, in Chicago, or in a galaxy far, far away.
    It looks like only the sda5 partition was encrypted, as well as the swap space.
    Sometimes, real fast is almost as good as real time.
    Just remember, Semper Gumbi - always be flexible!

    just posted this in another thread, but it fits here as well:

    if you admittedly have a hard time doing your own research, i really do not recommend full disk encryption!

    imho, the benefits of it, compared to home encryption, have no relation to the additional effort.
    in other words, full disk encryption is much harder than encrypting a non-boot partition.
