First you need to Boot into a Live CD environment and open up a terminal window. (applications–>accessories—>terminal)
Install required packages using the following command
sudo apt-get install lvm2 cryptsetup
probe required module using the following command
sudo modprobe dm-crypt
setup the crypto module to recognise the partition
sudo cryptsetup luksOpen /dev/hda5 crypt1
Enter your passphrase. You should get the following message:
key slot 0 unlocked.
Command successful.
If not, something has gone wrong.
Scan for volume groups
sudo vgscan --mknodes
sudo vgchange -ay
REMEMBER the name of the volume group, as you will need it later.
Create a mount point
sudo mkdir /volume
mount the encrypted volume to the mountpoint you just created.
sudo mount /dev/paulb-desktop/root /volume
The volume is mounted, now you can chroot or whatever else you need to do. If you would like to open the gnome file manager for writing to it issue the following command:
sudo nautilus /volume
Thanks!
I’ve just installed Ubuntu 8.04 on a encrypted partition with lvm a few days ago and wondered how to do this, if something goes wrong.
Never worked with lvm before…
Thanks a lot,
I’ve just broke my fedora system and was unable to access my LUKS-LVM “/” partition untill I found you tutorial.
you make me very happy!
I have SATA(hda) hdd with Ubuntu 8.10 + lvm + encrypt
/dev/sda1 * 1 60770 488134993+ 83 Linux
/dev/sda2 60771 60801 249007+ 5 Extended
/dev/sda5 60771 60801 248976 83 Linux
On other Ubuntu 8.10
andruffka@andruffka:~$ sudo cryptsetup luksOpen /dev/sda5 crypt1
Command failed: Can not access device
andruffka@andruffka:~$
what’s wrong?
wow, my encrypted volume is sda1, not sda5
and mount command like “sudo mount /dev/mapper/LABEL-root /media/MOUNTPOINT”
Unfortunately, I can’t get this to work from the live cd. Unknown command apt-get.
denali206, use aptitude instead of apt-get, it’s the same functionality.
