Just to repeat, since this suggestion has been made several times and I
guess in the flood of messages in this list folks are not reading the
earlier messages -- for this particular application, you need a filesystem
you can shrink back down, which xfs won't do, but ext2 will.   JFS can't
be shrunk either.

I must admit, the symlink plan (mount your new filesystem, point your
myth box to that new directory, symlink in all the old files to the new
directory) is the quickest and simplest, though you will not be able
to delete shows directly from the old disk until you reverse the process.
