Well, ext3 is pretty mature. If nothing else, its very easy to upgrade
from ext2 to ext3. Its as simple as creating a blank file and remounting
(file is the journal file). This is exactly what RedHat plans to do with
their next release of their distro.

Other options are:

XFS - SGI's foray into the journaling filesystem arena. Very well done
with lots of active development. But I'm biased as my group at work is
heavily involved in the development of this stuff.

ReiserFS - Another very good jfs that is being distributed with SuSE
distros as an option when installing. Seems to have a good following and
have relatively good benchmark numbers.

JFS - IBM's Journaling Filesystem. One of the oldest JFS around but only
recently ported to linux. The Linux port is perhaps the least mature of
all the journaling filesystems avialable for linux.
