Well, in my case I now have a script, triggered via a button in Webmin
so I can initiate it from my mobile phone over wifi if I have to, that
un-mounts the volume and "luksClose"s the encrypted partition, so it
might as well spin down the disk too, and avoid an emergency head park
(apparently there's a SMART counter for this).
