40.7 Jonah Notes


Jonah is a Dell OptiPlex 7000 Desktop. See Section 40.6 for installation details.

The storage setup is /dev/nvme0n1p6 (377GB) as root (/), /dev/sda2 (2TB) is encrypted as jaffa, and /dev/sdb (2TB) is trucrypt encrypted.

On a reboot the non-root disks need decrypting and mounting:

  • From gnome-disks decrypt the 2TB LUKS ST2000DM008-2UB102 and mount as /media/jaffa;

  • From veracrypt (run with sudo) decrypt the 2TB Seagate Expansion Desk using the Auto-Mount Devices option and mount as /dev/hafren. Takes a minute or two after providing the password.

Alternatively on a reboot the encrypted disk (crypto-LUKS) can be decrypted from the command line which prompts for the passphrase and an administrator’s password and decrypts the disk which can then be mounted:

udisksctl  unlock -b /dev/sda2
