Recent releases of kernel 2.4 have support options for the ReiserFS
journaling file system. If you're running Red Hat 7, you should just be
able to drop 2.4.2 onto your box, enable ReiserFS, compile, LILO, and
go; you'll also need the ReiserFS userland tools to actually make and
maintain your new filesystem, links to that should be in the kernel
source.
There are other contenders, including ports from other Unices (JFS from
IBM's AIX, EFS/XFS from SGI's IRIX) and the next version of e2fs, named
(surprise) e3fs. Last I checked none of these were available as options
in the main kernel distribution, you'd have to do go to the sites for
each project and patch their sources into the kernel tree yourself. A
quick google search should help with that.
XFS is neat because it will (well, should, eventually) provide support
for EFS, which is a sort of RAID manager on steroids; you can literally
construct file systems from disks housed across many machines on a
network, which will recover gracefully without data loss when
subcomponents fail out of the array.
e3fs is neat because it will be back-compatible with e2fs, much like
Sun's logging version of UFS for Solaris. Given a kernel with e3fs
compiled in, you should be able to just mount your existing partitions
as e3fs filesystems, maybe run fsck on them once, and away you go;
later, if for some reason you don't like e3fs or you need to move your
hard drive to a machine that lacks e3fs support, you can still mount
your e3fs filesystems as e2fs.

With all due respect to Kenny Rogers,
the best that you can hope for is a return code of zero.
Opinions expressed above are my own, and not those of my computer.
