Ext4 as default

Ext4 as default is not a good idea. Any loss of power can corrupt your file system to the point of not being able to recover. Unless you run a battery backup consider your choices.

That's not true. The fixes were merged for the kernel ahead of 2.6.30 release and backported to the rawhide kernel a while back. The beta release has the fixes already.

Moreover Eric Sandeen, one of the primary developers of Ext4 is a Red Hat developer and Fedora has included Ext4 as a option right from Fedora 9 release. We have solid testing, feedback and fixes for several releases now.

1) no "we" don't have solid testing because all this happened
2)2.6.30 is planned for summer (?) so it is not here yet
3) no it is not the same with backporting (there are some problems)
4) read Linus comment about ext4 about at lkml after 2.6.29 release.

Personally I like that Fedora pushes the bleeding edge a bit, if I wanted guaranteed stability I'd be running Debian or CentOS. As for Ext4 specifically, it's no worse than the old days of distros including ReiserFS as the default methinks. I distinctly remember some downright nasty issues in the 2.4 series with that one.

The patches for that issue are in the Fedora kernel already.

Of course, you shouldn't trust any data you can't lose to a beta release of any software.

But those patches still leave a very significant reliability regression for ext4 vs ext3. Ted is simply going to have to accept reality, bite the bullet, and part with the benchmark numbers he seems so focused upon... for the good of everyone.

Thanks for parroting this already stale news yet again! I've been running the EXT4 file system on my Debian box for months without any issues whatsoever and I highly recommend it. Of course I'll also welcome any patches that might minimize the odds of data loss. Speaking of odds, I think they're in my favor even with the file system as is. I'm not going to shy away from an advanced file system and its myriad features because the power just might go out on me. Do you constantly look up at the sky because you might get struck by lightning?
