Then I took closer look and found out this issue. After run this: fragfile="/vdf/testfile" for I in `seq 9 -1 0`; do dd if=/dev/zero of=$fragfile bs=4k count=1 conv=notrunc seek=$I oflag=sync done Even though the file does exist. e4defrag complains about: (this output comes from kvm guest machine) > e4defrag -v /vdf/testfile Can't get super block info: Success "/vdf/testfile" Is this a known issue or something I did wrong. Thank you! Jon
