Открываем The Linux System Administrator's Guide

Читаем Chapter 6. Using Disks and Other Storage Media:
------------------------------------------
6.8.8. Fighting fragmentation
...
The ext2 filesystem attempts to keep fragmentation at a minimum, by
keeping all blocks in a file close together, even if they can't be
stored in consecutive sectors. Ext2 effectively always allocates the
free block that is nearest to other blocks in a file. For ext2, it is
therefore seldom necessary to worry about fragmentation. There is a
program for defragmenting an ext2 filesystem called, strangely enough,
defrag [5] .

------------------------------------------
Т.е. факт фрагментации наличествует, но она незначительна и о ней редко
когда нужно беспокоиться. Но если вожжа попала под мантию, забирайте
дефраг на
