I'm a very happy user and fanboy of the ext3 filesystem. Search the fora though, there are lot of "which filesystem?" discussions. :P

Ok, OK, OK let me try, Pepsi vs. Coke, which you like better pros and cons?:wink:
This is an endless battle that leads to the same place as gnome vs. kde.
OK Google fight says Reiser wins but Reiserfs loose so I guess reiser4 is the future.:lol: . Anyways ReiserFS is in many ways better i have my system performing better in reiserfs than ext3. Even reiser4 runs super stable in my system and even faster than reiserfs and ext3.

If you were to provide details on what you intend to use them for, then someone may be kind enough to offer you a specific recommendation one way or the other.

But if you want general information on which is most suited to which tasks, then you should first try searching. There's plenty of information out there.

ext3: old, super stable, pretty fast, can convert from/to ext2 if needed. Would recommend for servers and such were nothing can go wrong.
reiserfs: faster than ext3, but not by much, less stable than ext3, but still very stable. Handles really small files really well. Would recommend for most people.
reiser4: super fast, just beginning to get stable. Handles small files really well. Would recommend for bleeding edge systems.
xfs: great with large files. filesystem can be corrupted if you dont shut computer off properly (it saves some stuff in ram and forgets to write to disk sometimes). great for that extra partition that will hold large files like .iso's or whatever.
ext2: really old, everything supports it, extremly stable. fast for small partitions, does not require ~50 megs for its journal like ext3/reiserfs/reiser4/xfs do. great for /boot partition, if you want one.

feel free to comment, thats the best I could come up with, and i am no professional by any means

Benchmarking between different filesystems. Also Google for reiser4 which is way better, although still with some problems to resolve through development. The " horses for courses" analogy applies here. It depends on what the system is being built for and what the particular partition is going to be used for (what type/size of files it contains and whether read, write access speed is important, etc.)

Unless you have something special in mind you won't do much better than going along with the handbook recommended solution.

I know fallow (formerly of love sources) has recently been a big proponent of the "back to basics" movement of ricer converts from Reiser4 to good old ext3. Personally, I dabbled with Reiser 3.4 (never Reiser4) for a while, but found myself switching to xfs for speed and stability concerns.

I just found Reiser 3.4 to inconsistent speed wise, and all the while I was worried that a single emergency shutdown was going to corrupt all of my data. This isn't as much a concern in Reiser 3.4 as it is in Reiser4, but the Reiser fs's in general are notorious for being unreliable.

Personally, I would suggest that you not use ext3, but use a faster yet still stable journaled fs like xfs. I see that Griswold has voiced some criticism of xfs's stability, but from pure anecdotal evidence, I have to say I'm more wary of Reiser than of SGI's xfs.

That said, because of the logistics of filesystem conversion, I still have a very large partition (250 gigs) in Reiser 3.4 that has undergone several emergency shutdowns, and it hasn't failed me yet.

Well, get with the program. Reiserfs 3.4 is outdated and no longer being deployed by anyone. Reiserfs 3.6 is very stable. Reiser4 is very new and still very unstable. Anyone who tells you otherwise is clueless....

reiserfs 3.6 is very stable.
Sorry, I meant Reiser 3.6. I'm not clueless either, and I don't appreciate your unqualified criticism.

It is hard to qualify criticism of someone who doesn't even know which filesystem they are talking about. But it wasn't directed at you, anyway.

:lol: Good point. :wink: I admire your evangalism towards Reiser (although not your belligerence), but in the end it just isn't worth the risk IMHO. If you feel it is, then use it and good luck.

i've been using reiserfs for many years and have had great success with it on my home systems. at work we use ext3 and i recently had a hard drive crash and was able to convert it to ext2 and rewrite the superblock. if it was using reiserfs would it have been able to recover itself without the manual assistance? who knows. it was a nice feature that it could revert and be fixed, however a different FS may have been able to fix itself.

Yep, but I think when reiser4 comes to main line I will reinstall gentoo on it :D .

I have not used xfs yet, although I have been tempted to put it on my /usr partition. However, with regards to the stability of the reiserfs I can tell you this:

Due to dodgy hardware I experience at least(!) one major system crash a day, 8O which requires me to pull the plug and then reboot. I haven't to this day (I am talking here for well more than a year and half!!!) had a corrupted file on my system due to these crashes. I did end up with a couple of corrupt lib files after I moved some directories around by gzipping them and I blame gzip for it, but not once by emergency crash recoveries. The machine boots up fine, reiserfs does its checks and off it goes bringing up the system.

On the other hand I read that as xfs writes things in ram, an emergency shut down could well cause irretrievable damage (hence it is recommended that you are running a UPS on your box).

In conclusion, if my experience is anything to go by I can vouch for the stability and recoverability of reiserfs, especially when compared to ntfs of M$Windoze, which ends up corrupting itself silly - even without a hardware crash!

Remember: you cannot set POSIX flags with Reiser!!

Ext3 is the best ever :D

Now a quote from the benchmark:
Quote:
The conclusion is obvious by the "Total Time For All Benchmarks Test." The best journaling file system to choose based upon these results would be: JFS, ReiserFS or XFS depending on your needs and what types of files you are dealing with. I was quite surprised how slow ext3 was overall, as many distributions use this file system as their default file system. Overall, one should choose the best file system based upon the properties of the files they are dealing with for the best performance possible!

Meh. My experiences with Ext3 and ReiserfSv3 show that they perform almost equally (Reiser wins by a very small amount) for average desktop/workstation use. Ymmv of course...

Moved from Installing Gentoo to Duplicate Threads. We had enough filesystem flamew^Wdiscussions, for example this one.
