Bill, your answer stopped mine.
I was just about to propose identical advices as you did (rename mount point
and use cpio -p) but in a worse english than yours.
What I could just add is about Bill's 8th step : don't suppress only LV but FS
reference too, using 'umount /tmp/data ; rmfs /tmp/data'. Removing LV only
(with rmlv) would leave FS stanza in /etc/filesystems.
