There is no plan for this to be made available until e2fsprogs
do it please :-)
This issue is still there from one year and I would like to migrate my XFS
filesystem.
This feature was added to Veritas filesystem, during the pleistocene epoch, and
a little bit later, after the the firt glaciation, was seen first time in XFS.

ext4 defrag / defragment
@Michael, I hope I had at least 3% of fragmentation )
Just performed a check on my 1TB partition (I use it in my Gentoo home server).
The partition is one year and one month old
917GB total, 871GB used, 37GB free, 10GB reserved
it is used as storage for audio and video files and for rtorrent.

I've recently been looking into this a little more. The kernel support

I did some testing and reading. A migration to a fresh Ext4 partition
seems to yield better performance than the e4defrag. Of
This feature request is now almost one year old.
xfs support extents and defrag since long time, but it doesn't support shrink
operations.
ext4 support shrink and extents, but doesn't have defrag.
What will come first? Defrag on EXT4 or shrink on XFS?
From a user perspective, unfortunately, we
@maxadamo,
E2defrag should hopefully be releasable in Karmic+1.There are still
a lot of bugs that are still being fixed in the defrag code, some of
which could cause data loss. They work fine if the system isn't under
stress, sure, but acid test is to make sure things work OK even when the
chattr +e works for me on up-to-date Karamic.

I was trying to follow Ted's guidance on this and couldn't get chattr to
add the extent option to the files. Ted told me by email to do this:
tune2fs -O extents,uninit_bg,dir_index /dev/yourfilesystem

Actually, the defrag stuff is in the current kernel now and e4defrag is
checked into the e2fsprogs repo. I've tried it and it works.

Good to know; has there been a release yet?

No release yet. e4defrag comes after the latest tag, v1.41.8.

The defragmentation support in ext4 is still a work in progress. The
current e4defrag essentially creates a new file that is the same size is
the existing file, checks to see if it is less fragmented, and if so,
invokes a ioctl which atomically substitutes the blocks from the new
file to the new
Thanks Ted. Even if it's not ready for heavy production use, it sounds
reasonable to have it included so adventurous users can test it out.
Perhaps that will catalyze work on tools to visualise the level of
fragmentation, and in turn tools to improve the defrag.

As long as adventurous users realize that e4defrag might destroy their
data, sure. There has been some discussion about initializing requiring
e4defrag to check for the existence of an environment variable,

recall reading that e4defrag was going be the proposed way to convert
files to using extents after migrating from ext3. But I get Operation

migration, so it looks
Just a quick comment if I may...
Reading the many discussions/forums etc. concerning ext4, I believe one
of the MAIN reasons that folk are looking to get a defrag tool running
is to 'refresh' files on their disk having moved from ext3 to ext4,
rather than worrying about the (minimal) benefits of
Is there any other tracker we can use to see the status of this

We won't be including any such tool until it's stable and integrated
into e2fsprogs upstream. It would be far, far worse to ship a broken
version of such a tool than to ship no defragmentation utility at all.
(Besides, our kernel doesn't have the online defragmentation patch yet;
I gather this is
The online defrag patch isn't ready for prime-time yet. It's getting
much better, but it's still not at the point where I'm comfortable
merging it into the mainline kernel yet, and the userspace API's are
still not yet set into stone. So the userspace component is not going
into e2fsprogs
I think :) this would go into e2fsprogs.
