Linux filesystems and fragmentation
I've read up quite a bit on the above mentioned topic and all I can find is that Linux filesystems do not need to be defragmented because "the filesystem is resistant to fragmentation." Can anyone point me to a more detailed explanation of why that is? Additionally, if a filesystem is filled up to capacity, inadvertently causing significant levels of fragmentation, and space is freed up, will filesystems like ReiserFS automatically 'defrag' itself through regular use? Can someone explain how this works?
