When john now logs in, he gets an additional password prompt and his crypted home directory is mounted automatically. When he logs out, it will be unmounted.

Show pids using filesystem:
fuser -m MOUNTPOINT
As the user, kill all process accessing drive:
fuser -km MOUNTPOINT
Then unmount:
fusermount -u MOUNTPOINT
Example:
fuser -km /home/john fusermount -u /home/john
