Just for the historical record (and because this post still gets traffic), Ubuntu 9.10 will ship with ext4 by default. This is already the case in the beta released last week.

[...] I wonder if btrfs will overrun ext4 before it’s even widely deployed. “Ubuntu 9.04 does not use ext4 by default” http://mdzlog.alcor.net/2009/05/01/ub… [...]

Thanks for the info Mackenzie, I have to confess, I didn’t inform myself very well then, I thought it’s free of bigger bugs. But it’s ok, I have my important documents on Dropbox and the movies/music I back up regularly to an external HD.

Lorenz:
The patch for the most common problem was backported. There are still other possible issues in existence.

I’m using ext4 for / and keeping /home on ext3. And I carry around a live cd in case ext4 eats itself :)

We included it because many people are willing to accept the tradeoffs, because they’re interested in trying out the latest technology.

ext4 wasn’t mentioned in the press release or release announcement, though we did include an item in the technical overview at http://www.ubuntu.com/getubuntu/releasenotes/904overview#Ext4%20filesystem%20support

The text there provides a pretty clear explanation of the risks.

so the bug still exists? I thought it has been sorted out. I run ext4 now and the perceived speed increase is around 100%! Start Up time seems halfed, overall responsiveness of the system feels much better…loving it so far, no data lost either (hopefully)!

It’s completely understandable, it’s a new technology, its put there mainly for those who like to be a bit more “bleeding edge”. Tho Intrepid and Jaunty ext3 are defaulted to size 256 inodes while before they used to be 128. It’s pretty much installed following the ext4 standards.

Why put the Ext4 support as an highlight in this release then? It’s like showing a candy to a kid and saying “No, don’t touch this”.

Could you also tell us what those bugs with ext4 are ?
What are the risks?
Thanks,
