i dont think red hat has an option to use reiser fs, although slackware does, perhaps try out slackware if you really want reiser fs

jfs is a cooler one. xfs is the coolest one.

Well those examples are taken a little out of context I think. Most of us don't use dual P4's with 2GB ram.

If you are currently using reiserfs, there is no reason to change it. ext2 is an old filesystem with no journaling.

ext3, reiserfs, XFS etal are all journaling filesystems, which is a bonus for quick startups and better filesystem integrity.

Of course, each comes at the price of more options in your kernel, and more maintenance from you: the sysadmin.

Like I said, unless you are really interested in filesytems and want to try them out you might as well stick with reiserfs, because it's fine. I use it myself for every partition except /boot, which is ext3, just to be safe.

So the older the filesystem the better?

Code:
Peak Performance Results:

EXT2      773 Mbps @ 44 clients
EXT3      660 Mbps @ 44 clients
Reiserfs  532 Mbps @ 28 clients
XFS       661 Mbps @ 44 clients
JFS       683 Mbps @ 40 clients
I saw that on http://lwn.net/2001/0830/a/jfs-comparison.php3 (ppuru posted this link)

It says EXT2 doesnt have journaling, i don't know what that means... why does journaling make the system boot up faster, explain how journaling works.... thank you alot -- i'd like to understand!

Also is states
Code:
In this test, JFS had the best peak throughput for journal filesystems,
and ext2 had the best peak throughput for all filesystems.  Reiserfs 
had the lowest peak throughput, and also had the most % time in
stext_lock
So I also don't understand why you're all pro reiserfs when it had lowest peak throughput...

Journaling filesystems have a journal in which they write what they're going to do before they do it. When in the middle of writing something they get interupted (like in a power outage), instead of taking forever to scan the disk and find any errors, they look in their journal to find out what was interupted. They are also a bit slower than non-journaling filesystems because everytime they write something they take note of it in their journal. Ext2 is faster than the rest, but if you didn't shutdown properly it takes forever to boot.

hmmmmmmm
im also wondering...
those links presented REISERFS performs slower than EXT3..
but why do you keep on using REISERFS than EXT3?

As i said, that study is a little out of context. The benchmark was performed om a dual P4, with 2gb of ram. Plus, certainly on my box I will never have up to 44 clients connecting at once..only a few webpages served once in a while, plus whatever I happen to be doing locally.

I am not really "pro-reiserfs", it just happens to be the default filesystem for the distro I use. I cetainly don't notice any lag, or delays when reading and writing files so why would I want to do something as drastic as change my entire filesystem? If your conviced by reading this that reiserfs sucks, by all means, change it to XFS or whatever...I just can't be bothered as it would be too much of a pain in the ass.

Besides, as some docs point out, JFS and XFS are not quite "ready for prime-time", so I just use one that has proven to be stable and reliable.

Here is another link I found that describes the different filesystems:
http://www.linux-mag.com/2002-10/jfs_01.html

Is it correct that reiserfs is actually better than ext3 for when you have directories full of very small files?

One drawback I heard concerning reiserfs is that it is not yet supported under LVM or software RAID, unlike ext3.

I have also read that, but I am not sure what exactly a "small file" is...
