Re: Best file system
i think really depens on what is your
depending on sizes of files you store in the
logical filesystem, ext3 has 3 alternatives: standard, largefile, verylarge. so
that it uses inodes table optimal which will affect the iosystem to reach
indexes/fileinfo and access file in physical rapidly.
there is another option you can choose is reisefs
(my fav) if you are planning that file system is used for web (/var/www or
/usr/local/apache/httpdocs). reiserfs is very good at that kind of jobs. i warn
you about it`s higher risks to get corrupt compared to ext3.
if your data is highly critical (/var/backup) or
mostly static ( /boot ), ext2 will be the best one that fits your needs.

Actually, yes! If your server has a UPS, and
will automatically do a
clean shutdown on power failure, then you should try
ReiserFS, XFS, and
ext3 under the workload you're expecting. If you
don't _know_ what your
workload is, then try using bonnie++ to get an idea of
characteristics of your filesystem and disk IO
If you server is _not_ going to have a UPS, then
you're pretty much
stuck with ext3, for the reasons detailed here:
You should still benchmark, though, if you care
about performance; there
are quite a few IO tuning parameters that can have
positive effects on
system performance (for example, changing the IO
scheduler can affect
database hosts positively).
If you don't care about performance enough to
benchmark, then I'd say go
with ext3: it's the default and is well
