The way I was told to do it, and which seems to work ok:

1. Shrink the fs to significantly smaller than the final desired size
2. Shrink the LV to the desired size
3. Grow the fs to fill the LV

I guess that could be a problem if the desired size is very close to the
amount of data already in the filesystem, but other than that it seems
to work.
