cryptsetup luksClose

[ms@xxxxxxxxxxxxxxxxxxxxxx (Marc Schwarzschild)]

Hi,

I am setting up an external USB encrypted drive. I can mount it
manually after I boot the computer. I understand that I must
issue the 'cryptsetup luksClose' after I umount the disk. How do
I arrange for this as part of the Debian halt process so it
happens automatically when the server is shutdown? What happens
if there is a power failure and 'cryptsetup luksClose' was not
executed?

Thank you,
Marc
