Crypt-Luks and Resize

[Oliiive]

Hello! I use Mint in my netbook for the whole disk and I need to resize my partition but I (badly I know) have crypted my system... Must I reformat/reinstall all, or can I resize it easily? Is there a solution to decrypt it?
It took me hours to configure my Mint, it would be a nitemare if I do it again...
It could be nice to have a "backup/restore" function...

Thanks for your help!

By design, since real data is obfuscated, a binary-encrypted partition is "full" and cannot be neither resized nor compressed. Don't you have LVM volumes, on top of the encrypted partition, that you would resize instead ?

I have /boot for 243Mo, sda2 extended of 297Gio and within sda5 crypt-luks for the same size.

It should have a function to uncrypt a partition, I own my netbook and I know my password...

sda2 extended of 297Gio and within sda5 crypt-luks for the same size.

Then your LVM volume group is located on top of sda5, holding all you logical volumes that you can resize with regular LVM tools and file system utilities.

For in-place unencryption, you would need extra disk space before performing the operation...

Ok could you tell me which tool can I use to resize then? Because it isn't possible with GParted
For unencryption I need space. Could I use a usb key (I have one with 16Go, or even external harddrive)

Thanks

Edit... Reinstalled Mint from scratch... Duh! So bad it doesn't have backup facilities...
