hello,
having used a Windows-based Truecrypt encryption with
pre-boot-authentication for some years, I want to do the
corresponding action under Linux. I am using Linux Mint 17 Cinnamon.
The system has one harddisk.
I already found, read and unsuccessfully tried out
-
http://blog.andreas-haerter.com/2011/06/18/ubuntu-full-disk-encryption-lvm-luks.sh
and
- http://community.linuxmint.com/tutorial/view/344
Both tutorials / scripts refer to older Linux versions.
Since I am new to Linux I do not know, what syntaxes may have
changed.
I got things working so far, using a VirtualBox machine, (so Mint 17
x32 is used):
- 200 MB primary partition ext3 on /dev/sda1
(unencrypted) as /boot
- 9,81 GB crypt-luks on /dev/sda2 (as seen from GParted)
This configuration boots up GRUB, Mint's green/white dots start
flashing.
Then I think a timeout appears - message reads:
"Gave up waiting for root device ...
ALERT /dev/mapper/ubuntu-root does not exist - dropping to a
shell."
When I boot up from CD, start "Preferences - Disks"
I can use the built-in unlock feature and I see
/dev/mapper/luks-0a410528-cde8-440c-891f-ef6068aad0b3
LVM2 Physical Volume (LVM2 001)
which consists of
/dev/ubuntu/swap (4.1 GB)
/dev/ubuntu/root (5.2 GB)
/dev/ubuntu/home (1.2 GB)
So, the partions exist and can be unlocked.
I also can mount e.g. /dev/ubuntu/root
Mounted at /media/mint/fc34585c-ca63-4b28-aaca-5a00f3776856
There is /etc/fstab present.
It reads
(...)
/dev/mapper/ubuntu-root / ext4 errors=remount-ro
0 1
# /boot was on /dev/sda1 during installation
UUID=30b080b5-9b39-46c9-9b61-2320efde52dc /boot ext3
defaults 0 2
/dev/mapper/ubuntu-home /home ext4 defaults
0 2
/dev/mapper/ubuntu-swap none swap sw
0 0
There is a good deal accomplished on my way to a disk encryption,
but some small problems still prevent it from running flawlessly.
I wish to have the system booting up and asking for the passphrase
to unlock all three partitions at once.
Help would be appreciated.
regards,
Andreas
