Filesystem Benchmark

[pitupepito2000]

While browsing I came along this very good article. I tried to do a search to find an old article that I remembered that Drag wrote about filesystems, but couldn't find it. Here is a the link:
http://linuxgazette.net/102/piszcz.html

I read that a while ago, I think. It was kind of interesting. But benchmarks aren't the biggest consideration for a lot of us when choosing a filesystem.

EDIT: Could you add a results option to the poll?

I thought that it already had a "results" option. If it doesn't how would I go about adding one?

I think there is an edit option either on the poll itself or it's an option when you're editting the post. Not sure, it's been a while.

It's not a huge deal. At the moment I have ext2, ext3, and XFS filesystems in different places.

As fast as that benchmark says ReiserFS is, I'll never use it again, the risk just isn't worth it.

 

[Flatline]

I've never lost any data using ReiserFS (although I don't use Reiser anymore because I heard a couple of horror stories). XFS seems to have some of the best recovery tools and it seems faster than EXT3, so that's what I use these days.

Yeah, I've used ReiserFS on a bunch on non-critical boxes and never had a problem.
Of course I did wait for it to mature a bit, say around 2.4.20 or so.

 

[drag]

I lost data from ext3 and lost data due to xfs.

1. Ext3 was writing to a superblock (apperiently) when the power when out. POOF. Lost my /etc/ directory. All the files in it were fine, but they now had names like 1003213412. Reinstall.

2. XFS. My cat was leaning to far to see out the window. Saw a rabbit or bird and jumped (or something), fell down (of course), onto the back of my computer. Killed USB, my mouse stopped working. X didn't freeze but was unusable. Switched out of X shut ti down. Kernel oops.
rebooted.
Still no mouse light. Rebooted, powered the computer down pulled plug, hit the power to drain all the power out of the power supply and motherboard. Rebooted. Played with bios settings a bit and USB was back.

X wouldn't start. OK... not a good sign. GDM worked, but I couldn't log in and have it work.
Went to console, logged in.
That worked.
ls
<kernel gibberish.>
!!!?!?
ls
<kernel gibberish>
ls
<kernel gibberish>
cd /
ls
bin cdrom dvd floppy initrd lost+found opt proc sbin sys usr
boot dev etc home lib mnt root share tmp var
? OK.....
cd
ls
<kernel gibberish>
Oh.crap. Figured it out....
cd /
sudo su -
umount /home
xfs_check /dev/hdc1

What xfs_check said I didn't like reading.

xfs_repair /dev/hdc1

And on it went.

Found out my cat obliterated my "drag" directory. Everything got stuck in lost&amp;found.
Everything was labeled 123123-type numbers. After their inode numbers I guess. However the directories themselves had lost their name, but the contents of those directories were fine.
So I went thru and manually renamed all the files and directories. Of coures I had no idea what the files were before they got obliterated. So I used vi and did a lot of searching thru binary files.

All 70Gigs of it. (of course by the time I was finished I was down to 48gigs with judicious trimming). Took like 6 hours (slow day at work though. which was nice. Renamed everything thru SSH)

Of course after all this was done my XFS filesystem was 80% fragmented. Oh, well. Didn't notice any difference, but I figured it was a good idea to start off with a clean plate. Copied everything over to another partition, reformated, and copied it back. Didn't even have to reboot once.

Stupid cat.

Do they benchmark GFS?




Google File System

I hear they were gonna, but they were 99,999 servers short.

 

[n0cmonkey]

I've had no problems with XFS. I lose power roughly once per week (atleast lately :|), and the machine is running fine. Haven't checked to see if anything has really been messed up though.

I have had the same experiences with FFS and softupdates too.

Using a prerelease version of ReiserFS would feel kinda like using a beta Windows release...

No I think it's would feel more like just using Windows, period.

bada-bing! Thankyou folks! har har har har.

 

[Haden]

I'm running XFS on 4 servers (10+2+2+1 disks) and on my desktop. Despite having multiple hw problems over time (power failures, bad cables), xfs never let me down.

A lot of people over in the gentoo forums have at least one partition running reiser4

A lot of people on the gentoo forums probably think that all of those compiler optimizations are worthwhile.

A lot of people on the gentoo forums can read instructions....not much more

Still, most of the people I have spoken to on there know their sh!t. :beer:

Gentoo is mainly about rc-scripts, USE variables, and portage. That's why most people use gentoo.

And reiser4 looks to be worth it...

But that's the beauty of linux... someone tests it and perfects it for everyone else.

I thought the beauty of FOSS is that *you* could test it and *you* could fix it for everyone else.

Where you means anyone really.

Anyhow, these thoughts don't prevent bugs. If Reiser is really rewriting everything from scratch all the time, he's probably introducing new bugs and quite effectively bringing back the old ones. You remember the old ones, the ones that corrupted data all the time?

 

[Nothinman]

Right, just like the previous versions of reiserfs have been 'perfected'? Pardon me if I don't convert all my filesystems right away.

 

[n0cmonkey]

The point is, MAKE BACKUPS! No matter what FS you're using.

 

[Sunner]

Well, maybe Reiser has learned something from the experiences with ReiserFS 3?
One could always hope, ReiserFS4 could make an awesome FS, assuming it becomes stable, and gets good userland tools to go along with it.
