How To Remove Disk Encryption From a partition ( LUKS passphrase issue )

[Tuxic]

Hello, I am really getting irritated with trying to find an answer to this one. I was putting the last touches on a DELL laptop for my sister after installing Fedora 10 Beta. I spent days getting everything the way I want it.

But now, I remembered that I chose disk encryption during setup. What I really want is to get rid of the encryption pass-phrase so that my sister doesn't have to deal with authenticating twice once in LUKS on bootup and the other in GDM. I have been reading the cryptsetup man page. I don't see a single option that would allow me to unencrypt the disk or at least have it not prompt me for a pass-phrase.

If I try to remove the current pass-phrase, it goes like this:

[root@TBox ~]# cryptsetup luksRemoveKey /dev/sda2
Enter LUKS passphrase to be deleted:
key slot 0 selected for deletion.

WARNING!
========
This is the last keyslot. Device will become unusable after purging this key.

Are you sure? (Type uppercase yes):

OK I get that but what do I do then? I really don't want to format, it would take me ages to get back here after all the packages I have installed.

Hi there,

I would also like to know if and how is it possible to remove encryption from a LUKS protected partition.
Google doesnt help much in this topic (points here mostly).

As far as I my current knowledge goes right now, it seems one have to backup the files on the partition, nuke it, create new unencrypted partition and restore files from the backup.

as far as i know... it's not possible to decrypt the whole disk on-the-fly
copy the files somewhere, then format your disk, and copy all files back.

bye!!
