Journaling File System

[Joe Hood]

I've seen some retorts to the linuxgazette.net report from the Reiser4
fans, basically explaining that Reiser makes better use of unused CPU
cycles and that the single PIII 500 is not likely to reflect a
production system of today.

Ed is correct on the EXT3 being the only supported FS from the Redhat
kernel.  You would need to roll your own kernel.

Personally, I don't like the EXT3 system are large volumes, especially
if there is a crash, you have to wait a very long time for a FSCK to
complete--and with a production server, that's a lot of people
breathing down your neck asking, "Is it up yet?"

My preference, keep in mind I'm only running Redhat on my Oracle
servers and otherwise use Debian, is to use JFS.  Unfortunately, I
don't have many tests to throw your way as JFS is relatively new, for
more info on JFS: http://www.linuxjournal.com/article/6268
