Anyone Using EXT4 Having Problems?

'major' and 'minor' doens't really mean anything though, does it? It's as easy to fsck up and the result be a major bug and fsck up and the result be a minor bug is't it? besides, i think the bug your referring to was a known-about-bug, meaning it was KNOWN to not work with any kernels that was <2.6.28rc* at the time.. I might be confusing this bug and another though..

Actually , I wasn't referring to 1 bug . I just knew that rtorrent invoked more than 1 bug in the past .

The point is , Ext4 developement is not finished and the features need heavy testing . If you followed the mailing list you would know that bugs still show up .

Examples :

http://kerneltrap.org/mailarchive/linux … 274/thread
http://kerneltrap.org/mailarchive/linux … 024/thread

+1 for add plus warning. Seems very fair.

Make it a harsh warning, though. Filesystem bugs are sometimes very weird.

This isn't *buntu, people can handle themselves if it doesn't work, we don't need to be protected from ourselves. Add a warning and give us the choice....I really want to try Ext4 on secondary computer.

+1 for add plus warning.

This was fixed in 2.6.28rc3 or something.
The point is still valid . Some nasty bugs still come up . It's not wise to use a filesystem that receives a lot of patches (Patches that fix major issues not minor) .

That thinking would suggest we should never use any filesystems at all. Ext3 recently in 2.6.25 iirc had a bug which causes disks to get wiped, all the filesystems have major bugs from time to time. The fact that one comes up recently is not a valid point for concern.
For a point of reference, ext3 has had 6 fixes this month, ext4 has had 8, and ext2 has had none. Does that suggest we should all move to ext2 or that ext3/4 are receiving a lot more attention?

And on a side not, on the point of more patches and fixes, reiser and xfs have had no patches in the last month, does this mean they are totally stable? Or that since there is very little interest in these systems that bugs are not being fixed?

Edit: I stand corrected XFS has had 8 patches this month, on par with ext4.

Hmmmm...
I recently had this discussion with someone, is ext4 something we'd like to support in the arch installer out of the box already, or should we perhaps hold off for another kernel release cycle? After all, this will be the first kernel release that it is renamed 'ext4' instead of 'ext4dev'... is it something we should consider stable enough to offer as a menu option at this point?
Currently I'm leaning toward waiting another release cycle, with filesystems the tried-and-true tends to be more important than new-and-shiny, but I'm interested in hearing some opinions on this anyway? Should we perhaps wait 2 release cycles?

Arch is bleeding-edge sir ^^

+1 for add plus warning.

Once the 2.6.28 kernel is released, I think a fair amount of people will want to try out ext4, but will have to jump through hoops to get Arch installed on it. It's not hard, but kind of inconvenient. Yet another group will wonder why (read: whine) it wasn't added yet. So, my opinion is that ext4 support should be added to the installer sooner than later for no better reasons than 1) making the lives of group 1 easier, and 2) avoiding group 2 altogether.
The people who have important data should be smart enough to make a more conservative choice of file systems.

agree completely

I do agree with you for the most part .

The way I see it though :
* Ext4 = Ext3 + promised new features .
* Some of the new features are working very well .
* Some new features are not (most notably delayed allocation and to some extent multi-block allocation) .
* Am I making false accusations ? well , follow the mailing list and you will know that a new issue (bug) shows up almost every week due to the instability (unfinished work) on those features .

-------------------------------------
Anyway , I feel like I'm submitting a lot of useless posts . So I would agree with others . Adding support with a big threat-like warning is not a bad idea .

So, those of you who use Ext4, have you had any problems yet? I plan to use the new file system for / and /home, but if anyone has a horror story to share I might reconsider. ;)

I've seen nothing but improvements over Ext3.

Nope.

using ext4 in 4disks soft RAID5, using big files, no problems so far. already 2weeks 24/7.

Wintervenom · 2009-02-10 06:29:48

I have come across problems, and that is when the system crashes.
On six occasions, when the system went down (fucking Catalyst!), I logged back in to discover that the settings for whatever applications I had open, including the desktop environment, had been annihilated to zero-byte files. After the sixth occurance, which occured right after I had finished setting up a fresh install two days ago, back to Ext3 I went.

Been using ext4 on a complete / partition including boot with no problems after the initial install. Happy so far.

Possible bugs are argument against USING ext4, but not adding it to installer
Arch is bleeding edge, add the option, with a warning

toad · 2009-02-10 15:00:36

Quick interlude to OP - no problems yet. Setup: fstab mounts all partitions ext4 but physically I have only converted my multimedia partition. Others to come...

And back to installer: include +1

I totally agree. Yet I would not use ext4 for at least a year or two until it receives enough testing and fixes.

Exactly the same here. All my partitions have been mounted as ext4 for about a month; MM partition converted about three weeks ago.

And back to installer: include +1

+ another 1, if users' opinions are being counted.

Arch Linux
