I too like reiserfs. I've been using it in a development system for
several months without a data failure. There is only one thing I noticed
that makes it not perform like ext2.

We have a data acquisition program running in the linux box. The data is
stored to disk in fixed block sizes. At the same time another program is
displaying the data on the monitor. This program checks the data file
periodically for new blocks to display. When running on a reiserfs
system, the update stops and I have to re-read the file to display the
new blocks. In an ext2 system I don't see this behavior. It seems like
the file's info is not updated quickly enough. On the other hand these
data files can be large, several megabytes, and as I understand it,
reiserfs is best suited for small files (although I don't know how small
"small" is.)
