Will copying the contents of the snapshot over the original logical
volume do what you want? If so, this can be done as follows:
# mount /dev/vg/snapshot /snap
# mount /dev/vg/original /orig
# (cd /snap; tar cf - .) | (cd /orig; tar xvf -)
Of course the v option on the second tar invocation can be omitted to
avoid seeing all the filenames of the files being copied.
Sincerely,
