Is the last sector of a partition free?

How can I tell if the last sector on a partition is used by the file
system?  I'm sure there's an easy way, but can't figure it out.  (I
have a couple file systems I'm considering switching over to gjournal,
but would like to know if it'll work before I schedule downtime.)
