Michael Johnson wrote in to let us know that he's updated Red
Hat's white paper on the use of ext3: "There is a lot more
information in this new version, and that information should answer
questions that were posted in talkbacks and such, so I am guessing
it would be interesting to your readers."
"In Red Hat Linux 7.2, Red Hat provides its first
officially supported journaling file system: ext3. The ext3 file
system is a set of incremental enhancements to the robust ext2 file
system that provide several advantages. This paper summarizes some
of those advantages (first in general terms and then more
specifically), explains what Red Hat has done to test the ext3 file
system, and (for advanced users only) touches on tuning.
Other journaling file systems are being written for Linux; this
paper does not address them in any way and is not intended to
compare ext3 to any other journaling file system."
