what's wrong with e4defrag that it pretends it reduced th efragments of a file to 1 while in the next "e4defrag -c" (why does that only list 5 files at all) the same file is listed again with the same old frag count?

You might want to examine the actual allocation before and after with "filefrag -v"
which could offer some clues to whether anything was modified by e4defrag.

(I would also suggest that there is no need to defragment a 3-extent 2 megabyte
file, in general.)

it's not a question if it's needed

the point is it pretends "Success: [1/1]" but a following "e4defrag -c" still says "now/best 3/1"
