Message-ID: <194f62550907240636o5ba623cdy1f16deb7f6d70eeb@mail.gmail.com> Date: Fri, 24 Jul 2009 09:36:53 -0400 From: Clemens Eisserer <linuxhippy@...il.com> To: linux-kernel@...r.kernel.org Subject: Status of ext4 online defrag? Hello, Does anybody know what the current state of ext4 online defrag is? Although ext4 does an excellent job in avoiding fragmentation, sometimes it still happens, e.g. with firefox's sqlite database which made using firefox horrible because disk-io took ages (and took also some time until I found out whats the problem): > [ce@...alhost ~]$ filefrag /fc8/home/ce/.mozilla/firefox/default/places.sqlite > /fc8/home/ce/.mozilla/firefox/default/places.sqlite: 1730 extents found, perfection would be 1 extent Thats 1730 extents for a 75mb file :-/ Sure I can copy it between my partitions, but I would really prefer a defrag tool ;) Thank you in advance, Clemens -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@...r.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
