Hi, This is for Red Hat Bugzilla: https://bugzilla.redhat.com/show_bug.cgi?id=641926 It is possible that e4defrag causes a segfault when someone removes a defragging file. The following patch fixes this problem. How to make the newest e4defrag: 1. Download e2fsprogs git tree # git pull http://git.kernel.org/pub/scm/fs/ext2/e2fsprogs.git 2. Apply the patch I sent a while ago http://marc.info/?l=linux-ext4&m=128272690010784&w=4 3.
