Even if it's highly fragmented, you'll rarely gain more than 25% boost in
performance by defragging for most linux filesystems. Unlike fat32 where
you can gain many times 100% better performance.
ext2 does have e2defrag which is part of the defrag package in my debian
system. I've used it, but most of what you gain is a little drive space
from more efficient use of the device. And running updatedb plus ldconfig
seems to help about as much if not more in the efficiency department. But
I don't run cron and therefor don't run the run-parts job that runs those
on a daily basis.
You can always tar up the partition, mkfs, then untar it back in most
cases. And in many respects this is better and more efficient than most
defrag programs. Of course tar assumes you have another partition/drive
to use that is large enough to handle the process.
Many put /var/log/ and others on their own partitions to avoid
fragmentation where it counts. As well overcoming other issues which is
probably more of a motivator than fragmentation.
