Troubleshooting/Known issues

The mountpoint is not mounted

After reboots, discs are not decrypted and mounted - this is the intended behaviour (and, indeed, the reason we have this process in the first place), so we don't need to enter the passwords via console (where oftentimes keyboard layouts are ill defined), but can copy/paste them once the server is up and running.

Solution

Simply use

# Non systemd:
sudo service mountcrypt start


# With systemd:
sudo start-encrypted-devices

and enter the password (which you should find on https://password.vshn.net)
