Is there a way to do full disk encryption after the install?

I have Ubuntu 11.10 installed with /home encrypted but really need the whole drive encrypted. I would really like to do that with out a re-install. Is there anyway to do that?

No. Part of full disk encryption, Truecrypt or otherwise, is writing random data to the hard drive.

Best you could do (without a re-install) would be to migrate your home to encryption or make a encrypted data partition. You could use Truecrypt or LUKS (I personally use LUKS).

"writing random data to the hard drive" - this is totally optional and not the root cause for marking this not possible. One could change the initramfs configuration, crypttab, fstab, make a separate /boot partition, copy everything over to a new encrypted volume. It's hard, though. I would re-install everything copy data back as well. – gertvdijk Dec 18 '12 at 12:16
