Reiserfs is actually working.
We are doing our last performance tuning experiments, and are benchmarking it.

Don't be locked out of the source, and doomed to life in the slow lane.
Dump NT! Get Linux (http://www.kernel.org) plus ReiserFS
 (http://devlinux.org/namesys).  If you sell an OS or
internet appliance, buy a port of ReiserFS!
Speed matters.  Trees are fast.  Go faster!

dtfs holds lots of promise mostly because its the closest to actually
working 8) and it is fully compatible with ext2. From what I remember you
just plug in 'fs personality modules' into dtfs and presto, you have
logging for XYZfs.

Aside from a real LVM (eg growable fs) the lack of a logging FS is the
last big hurdle towards Linux HA. There are lots of smaller hurdles though
8)
