How to mount and un-mount an encrypted disk?

To mount and un-mount the encrypted disk you must use systemctl rather than the usual mount and umount commands. Mount the disk with systemctl start mnt-data.mount, and un-mount with systemctl stop mnt-data.mount The systemd units are executed only after the network and the other “normal” filesystems are mounted.
