What filesystem do you use?
 

I use reiserfs because i heard its the fastest, but i don't know much about the others...

can anyone give me a short explanation in the advantages of using one filesystem over another one?

You can get an overview of various filesystems here
I user reiserfs.

I've used reiserfs for some years now. It's journalled, fast and stable.

I use reiserfs because Pat and Bob said to.

I've been using Reiser for years without any data-loss, on
a wide range of hardware, through several distro's.

It's fast, stable. Nuff said ;)

Reiser it is!

My /home partition was ext3 for quite a while since it had too much stuff to easily back-up, but now it's reiser across the board.:D

Reiser and Slack just seem to go together.

I use ReiserFS, though I use XFS on mass storage drives.

Yeah i'm also a reiserFS fanboy. when I was first trying out slackware I just used ext2, but the next slackware install I tried using reiserFS I noticed a huge performance boost from reiserFS.

reiserFS I recommend for anyone.
Too bad that the Symantec Nortons Ghost only supports ext2 and ext3 so far :(

So? :)

Use dd or partimage ;P

I use XFS.

I also use ReiserFS. Seems good to me.

Is there a major difference in speed between the ReiserFS and ext3 however? I've used ext3 fine for the past x years and never had any problems or issues.

nevermind, I answered my own question. For those of you interested... check this link..

http://linuxgazette.net/102/piszcz.html

General purpose: ReiserFS.
Very large files: XFS.
Small partitions like /boot: ext3.

Be careful with ext3: It caused my machine when I copied large files from an arbitrary partition to a 40GB ext3 partition. I tried ReiserFS on that partition, which was ok, but finally found XFS to be faster in writing large files. Again:

Don't use ext3 for large partitions!!!

On the other hand: A consulting firm (I don't remember their name) says it has changed their recommendation from ReiserFS to ext3 for Oracle databases, recently.

And the German Linux Magazin has published benchmarks showing IBM's JFS to be the least configurable, but still overall the fastest of the file systems available in Linux. It was the only file system in their test that showed top speed in every benchmark they did; JFS finished 1 or 2, which made it 1 overall. So you might give this one a try. (I have no experience with it, myself).

Don't use ext3 for small partitions, either. :}

My /boot for instance is only 36MB, if I used
ext3 (with its 32MB journal) I'd have difficulty
to have more than one kernel with system.map
and all... ext2 for /boot ;)

I use reiserFS now, was using ext2 before and haven't noticed much difference expect it doesn't scan the disk every 13 boots.

reiserFS, because it was the default option and because someone pointed me to theGentoo docbook which explins some of the differences. It seemed to be the most sensible thing to do.
Are there any good reasons for using 'older' systems like ext2 or ext3?

used to use reiserfs but stupid gdesklets won't read my damn harddrive size correctly, so im back with ext3( i know pathetic, i had to rebuild anyway) - ihavent noticed any performance difference between the two

ReiserFS it's way faster than ext3 :cool:

XFS

I use reiserfs because it's standard in the slack 9.1 install :jawa:

I just wanted to add something about reiserfs.
Once i left my computer open all night and the batteries just died, when i woke up in the mornning and tried to start linux i got a kernel panic, tried to boot from a floppy but still i couldnt get to my system so i just had to reinstall everything again ! just for the record, i sware this is true. I still use it tough, it's fast indeed,

regards

reiserfs4, it's like lightning :)

I wonder when reiser4 is going to get into the default 2.6 kernel, would be great. Currently using reiserfs and no problems so far. Seems faster than ext3

Actually reiserfs has had some latency issues with the 2.6 kernel, and is much slower than with the 2.4 kernel (appearently). Interesting article on this on kerneltrap. So it may actually be slower than ext3 with the 2.6 kernel.

Reiser4 does not suffer from these issues because its nearly a complete rewrite from 3. I would expect it to be merged into 2.7 development sources though, don't hold your breath.

I use Reiserfs from suse, now in slack i used too but i am thinking to migrate to XFS. i want all my partitions and hard drives to be linuxes. music+movies - XFS , /home -reiserfs / -ext2.

I always use reiserfs because once somebody told me to.....

Well, i did.....
.... with several distros....
....small partitions and large partitions.....
....and i never had any problems with it.....
.....so i stay with it :)

I use ReiserFS mainly because I liked it when I had Gentoo installed (emerges were lightning fast when using ReiserFS, compared to ext3 and jfs). Hadn't had any problems with it, but I switch distros and filesystems so often that I haven't used it over an extended period.

For some weird reason I used JFS when I erase and reformat the HD on my iHP-120 (I needed all the space for backup). Bummer, since it contains mostly Windows stuff, and Windows can't read the partition :p ... bah, extra work...

reiser4 because reiser 3.6 has been so good to me. When the power goes out, my system's still there....

being that i am still in my first actual linux install i went with the recommendations on the slack disk.

ext2 /
ext2 /home

slack said that ext2 was stable and fast, and i thought it said that /boot must be ext2...i also chose the highest inode density possible and think i'm suffering for it with available drive space. since i haven't tried ext3 or reiserfs, what exactly is the benefit of a journaled file system? is it purely speed? if reiserfs is that much better, is there a simple way to convert?

Reiser, the fastest one installed by defautl supports b-tree that helps a lot when you actually have thusands of directories and thousends of files in each directory files with an excelent journal system.

Not much choice on Fedora Core, using ext3 hopefully they'll support reiserfs soon.

Nope. Redhat don't like it. Bitch to them. ;)

With a journaled file system, you don't need to scan the drive if it gets shut off without unmounting (i.e., power outage). This helps against corruption.

You can convert ext2 to ext3 by booting off a CD, leaving your drive unmounted, and typing tune2fs -j /dev/hda1 (or whatever it is).

Is there anyway to convert ext3 to reiserfs? Or would I have to reinstall Slackware in order to use reiserfs?

It's good to see Paul Reiser has found a new career, after Mad About You went off the air, ;)

I don't think there is, no. :(

I am currently using ext3 but after reading all of the comments you guys have posted about reiserfs I feel tempted to try it out. :)

hda1=ext 3
hda2=reiserfs 3.6

I get about 32MB/s on hda1

what's the trade-off?
how much more space does a journaled file system need?

...about 32mb for the journal

that's not much

and seeing as i think i might have hit some corruption after a power loss today i'd kinda like to try it out, but i don't want to have to start from scratch unless i absolutely have to (critical system failure)



anyone think it's possible to:
backup / to /home
change / from ext2 to reiserfs
restore / from /home
backup /home to /
change /home from ext2 to reiserfs
restore /home from /

any known problems, suggestions, recommendations?
or is ext3 my only option?

If you're feeling brave, go for it. I did a similar thing, but when I restored / my boot loader was corrupted and I had to reinstall :(. I think you'd be fine with changing /home, and if you have a /boot partition you could do / too...

The new statistics for Reiser 4 say:

Copying - Reiser 4
Overwriting - Reiser 4
Deleting - ReiserFS (Ext3 is faster than Reiser 4 at deleting)

I am using Ext3 only because it was painless to convert from Ext2 ( I didn't have to format my HDD )

you had to reinstall slack or you had to reinstall lilo?

brave? hmm... i'm willing to take a certain amount of risk, but not willing to risk having to reformat. i reformatted and reinstalled slack countless times in the first couple weeks after switching to linux. if it is necessary i won't have a problem doing it again, but not by choice. it would probably take me weeks to get the system back to where it is now.

so...booting from cd or floppy and executing "tune2fs -j /dev/hda1" and "tune2fs -j /dev/hda2" is basically risk free. the only possibility that would worry me (with either ext3 or reiserfs) would be a power failure during the conversion process. the power has been off and on here for days so whichever fs i decide on going with i'm going to wait until power has been stable for like a week straight.

when you backed up each partition to another partition before a format, what method did you use? did you tar the partition, create an image, etc? and for the format would it just be "mkfs -c -v -t reiserfs hda1" and "mkfs -c -v -t reiserfs hda2"?

i decided to go the "safe" route

followed the instructions earlier in this thread for converting
ext2 to ext3. the process was incredibly fast, i was expecting
it to take about the same amount of time as a low-level format.

i haven't been timing anything, but my boot seems to be
completing faster than it used to under ext2 (even when the
disk did not have to checked for errors)

i use reiserfs, i used to use ext2.... but then i decided to reinstall slack and give reiserfs a try. pretty happy with it.

JFS for multimedia content (especially big video files).
ReiserFS for everything else.

I installed my slack 10 with da ext3, but later, desided 2 "jump" 2 reiser( i read about a new version... http://www.namesys.com/). Now i found a way to change my linux FS without reinstalling slack, if my experiment will have success, i'll wright sm guide =)

cool beans

hope it goes well
let us know how you did it if it works

ext3 vs Reisers on Redhat
 

Hopefully sometime RedHat will understand.

I am Using LVM and SuSE in a Prod environment.
I can enlarge my filesystem while my Oracle database is running !!!
(lvexpand + resize_reiserfs)
And it woks !

You cannot do that with ext3.
You have to unmount the ext3 filesystem (Stop database) , enlarge it, then mount it again.
I cannot to that in ther middle of the day

Until ext3 can do that, do even think to go ext3.

P.S. Unless you are willing to get up at 3am, to stop production machine to enlarge the ext3 filesystem.
