** Description changed:

  I'm using Ubuntu 12.04 dev with e2fsprogs 1.42~WIP-2011-10-16-1ubuntu1.
  I wanted to defragment a big file (~9 GB) but sometimes e4defrag does
- nothing because it thinks the file is optimized and a few seconds later
- it defragments the file and is reducing the most times the extents of
- this file. Here is an example:
+ nothing because it thinks the file is fully optimized (I guess). But a
+ few seconds later, when I try to run defragmetation again, it decrease
+ number of fragments. Here is an example:
  
- Command: e4defrag -v '/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi'
+ ~ $ e4defrag -v '/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi'
  Result: [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:	100%  extents: 71 -> 71	[ OK ]
  
- The file was'nt defragmented and directly after this I used the same
- command again and got:
+ The file wasn't defragmented at all, but immediately after this I used
+ the same command again and here what I've got:
  
  [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:
  100%  extents: 71 -> 69 [ OK ]
  
- The file was now defragmented. I tried the command again:
+ The file now was defragmented a little. I tried the command again:
  
  [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:
  100%  extents: 69 -> 69 [ OK ]
  
  The file wasn't defragmented but on the next try:
  
  [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:
  100%  extents: 69 -> 68 [ OK ]
  
- The file was defragmented and the behaviour on the last try was a little

  [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:
  100%  extents: 68 -> 68 [ OK ]
  
- The extents wasn't reduced but the file was defragmented which needed
- some minutes. I don't know why e4defrag is sometimes defragmenting an
- already previously defragmented file and sometimes not. And why aren't
- the extents reduced to the minimum size possible on the first try?

Title:
  e4defrag doesn't make an optimized defragmentation

Status in e2fsprogs package in Ubuntu:
  Confirmed

  1.42~WIP-2011-10-16-1ubuntu1. I wanted to defragment a big file (~9
  GB) but sometimes e4defrag does nothing because it thinks the file is
  fully optimized (I guess). But a few seconds later, when I try to run
  defragmetation again, it decrease number of fragments. Here is an
  example:

  ~ $ e4defrag -v '/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi'
  Result: [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:	100%  extents: 71 -> 71	[ OK ]

  The file wasn't defragmented at all, but immediately after this I used
  the same command again and here what I've got:

  [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:
  100%  extents: 71 -> 69 [ OK ]

  The file now was defragmented a little. I tried the command again:

  [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:
  100%  extents: 69 -> 69 [ OK ]

  The file wasn't defragmented but on the next try:

  [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:
  100%  extents: 69 -> 68 [ OK ]

  The file was defragmented. After the next try:

  [1/1]/virtualbox/VirtualBox VMs/Ubuntu 32 Bit/Ubuntu 32 Bit.vdi:
  100%  extents: 68 -> 68 [ OK ]

  The number of extents wasn't reduced but as the programm says the file
  was defragmented, and it needs couple minutes to run. I don't know why
