The storage setup is /dev/nvme0n1p6 (377GB) as root (/), /dev/sda2 (2TB) is encrypted as jaffa, and /dev/sdb (2TB) is trucrypt encrypted.
On boot, the encrypted disk (crypto-LUKS) needs to be decrypted:
udisksctl unlock -b /dev/sda2
This prompts for the passphrase and an administrator’s password and decrypts the disk which can then be mounted.
On a reboot the non-root disks need decrypting and mounting:
From gnome-disks decrypt the 2TB LUKS ST2000DM008-2UB102 and mount as
From veracrypt (run with sudo) decrypt the 2TB Seagate Expansion Desk using the
Auto-Mount Devicesoption and mount as
/dev/hafren. Takes a minute or two after providing the password.
