how to recover your LVM encrypted partition after a motherfucker deletes the /boot folder
debian, howto 1 Comment »Here it goes, what I’ve learned today about LVM encryption:
To have access to my encrypted volume group, from an Xubuntu live install cd, I had to:
sudo apt-get install lvm2 cryptsetup
sudo modprobe dm-mod
(this is for preventing the error “mount: unknown filesystem type ‘LVM2_member’”)
Then we check out the partition table with the GParted and go after the ” unkown” partition:
Then we decrypt the volume with the passphrase:
ubuntu@ubuntu:~$ sudo cryptsetup luksOpen /dev/sda5 cryptodisk
Enter LUKS passphrase:
key slot 0 unlocked.
Command successful.
(where /dev/sda5 is the device that appears as ” unkown” to the GParted )
Here the name of the volume group is razorgirl
And the devices will appear on my /dev tree, as /dev/razorgirl/root, /dev/razorgirl/home, etc
So I can do now:
sudo mkdir /mnt/razorgirl
sudo mount /dev/mapper/razorgirl-root /mnt/razorgirl
And start all the burocracy of the chroot and the reinstall of the linux image, that the sucker of course forgot to delete…
ubuntu@ubuntu:~$ sudo mount /dev/mapper/razorgirl-home /mnt/razorgirl/home
ubuntu@ubuntu:~$ sudo mount /dev/mapper/razorgirl-usr /mnt/razorgirl/usr/
ubuntu@ubuntu:~$ sudo mount /dev/mapper/razorgirl-var /mnt/razorgirl/var
ubuntu@ubuntu:~$ sudo mount /dev/mapper/razorgirl-tmp /mnt/razorgirl/tmp/
That will have to wait till I come back from the Hackmeeting.
But at least I get the contents!
Special note to the motherfucker: I think I will start a mailing list for all the loosers like you that hate me and cannot accept the fact that I got bored of their bullshit. But to fuck me up takes much more, sucker. You’re not even worth revenge. And thanks for all I’ve learned today about LVM)References:
