So is this part of the manpage out of date?

" The  resize2fs program will resize ext2 or ext3 file systems.  It
can be used to enlarge or shrink an
       unmounted file system located on device.  If the filesystem is
mounted, it can be used to expand  the
       size  of the mounted filesystem, assuming the kernel supports
on-line resizing.  (As of this writing,
       the Linux 2.6 kernel supports on-line resize for filesystems
mounted using ext3 only.)."
