Have you already tried to put an "lsof|grep '/usr/';sleep SomeTime" into your
shutdown script before the umount in order to find the bad guy(s) aka
processes ;-) which have files still open?
Then you might enhance scripts to shut them down correctly.

In general: there's no danger related to not running "vgchange -a n" on your
            VG(s) because nothing is written to the PVs at all today.
