I have a problem. When I install Ubuntu, I make only one partition and encrypt this partition. Now I want to make second partition with different file type. How I can "decrypt" partition or... take 100GB from existing 500GB partiotion.

P.S. I already tried from "boot cd" but gparded have problem with encrypted partition.

How I can:

a) Make second partition from "live system".

b) Take encryption off, so gparted from "live cd" can do the work??

    There is no way to do this. Backup your data, music, photos, and videos. Reformat your hard drive and start from the beginning. – user68186 Feb 04 '15 at 19:14
  • There is no other way, to resize encrypted disk other than format hard drive? :( – zchpit Feb 05 '15 at 14:20
  • I will be happy if someone tells me, I am wrong. But, as far as I know, it can't be done. – user68186 Feb 05 '15 at 14:58
  • There are ways to enlarge a partition, but shrinking I'm not so sure, should be possible for ext filesystems... You might be able to use a live dvd/usb and "decrypt" the encrypted drive/partition (cryptsetup luksOpen), then shrink the ext3 filesystem (probably removing the journal & using resize2fs), but then you'd have to shrink the LUKS "container", and I don't know how to do that... – Xen2050 Feb 06 '15 at 15:56
  • @Xen2050: too complex and error-prone... See answer below. – Fabby Feb 08 '15 at 12:35
  • I don't had time, so... I made backup and restore :) – zchpit Feb 09 '15 at 08:53

"Great security comes with great responsibility"... ;-)

The conclusion of @user68186 is correct: backup everything and recreate. I would back up everything twice: one system back-up using CloneZilla disk-to-image (will be encrypted as well) and one file backup (please do that one unencrypted to avoid more trouble later on, use your current back-up program.) of the following directories: 

bin        Videos     Desktop    Pictures                 
Documents  Music      Public     Downloads  Templates

Read this Q&A on the strategy to use. You’re definitely user type 4!
