I want defragment my root ext4 partition after upgrade to 10.10. But I can't find e4defrag in standart repos. May I build it from source? And is it safe for use?

UPD: Now in 12.04, we have e4defrag in repos. Just tried it, and it works well! I see some speed improvement. Simply run e4defrag /dev/sda1


According to one of its developers, Akira Fujita, e4defrag needs more feedback - which IMO translates to "not ready for prime time". I wouldn't use any defragmentation tool that's not thoroughly tested.

Here are some interesting slides from his recent talk at the LinuxCon 2010.

e4defrag is now in the development version of Ubuntu 12.04, see its man page for details.

  • Thanks! Is there any up-to-date information? Is there any source, where I can check on my own? Surprisingly Google coudln't answere this for me.

    Good link - but this answer should be updated, it's been in official repo for some time.
