** 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 - different: + 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 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? + 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 + 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? + + It think at least there must be an option to fully defrag. Or, for + example, option to set minimum size of fragmented slice or something + like that
