I have a LUKS external partition that is automatically opened/mounted and closed/unmounted by pam_mount during login and logout. Right now I am having to log out in the terminal and then shutdown using the GUI at the login screen.
I want to write an alias for the command gnome-session-quit && shutdown -h now to make this quick and easy but I don't know if this would affect the LUKS partition in any way if I don't give it enough time to gracefully unmount and close. I don't want to boot into a session where my encrypted drive fails to work because this command crashed it while it was still doing I/O operations.

Shutdown will wait for disks to be unmounted. See https://serverfault.com/questions/327758/linux-graceful-shutdown or https://www.tldp.org/LDP/sag/html/shutdown.html
The command you've posted will shutdown without data loss from filesystem corruption.

So the command will work? Thats good to know, now I can make an alias for it. Your link does ay that shutdown is graceful, but it doesn't address whether pam_mount will still close the LUKS encrypted drive.

@MyWrathAcademia if the partition is cleanlyumount'ed, it shouldn't matter whether or not it gets aluksClosesince that doesn't do any writing to the drive itself anyway.

thanks @Xen2050. Do you think I should set a timer in between the log off and shutdown, in order to ensure the partition is cleanly unmounted, e.g.gnome-session-quit && shutdown -h 1? Or is a delay not necessary in your opinion.

@MyWrathAcademia I'm not sure what gnome-session-quit umounts, but shutdown should be doing safe umounting anyway. Unless you're seeing errors (like dirty filesystems) I probably wouldn't bother with a delay, but if it's just a few seconds that might not be a big deal either

@MyWrathAcademia if the partition is cleanly
umount'ed, it shouldn't matter whether or not it gets a luksClose since that doesn't do any writing to the drive itself anyway.– Xen2050
