If this is the old e2defrag then the answer is "just don't use it", because
it is very old and will corrupt your filesystem.

Why do you think your filesystem is fragmented, is the first question.
If it is then you should delete as many files as you can (or move non-
critical files to another filesystem), and then rewrite the files in
single stream copies.
Using ext4+mballoc+delalloc will almost entirely eliminate fragmentation,
but it isn't in any released kernel yet.
