Shake project is a defragmenter that runs in userspace, without the need of patching the kernel and while the systems is used.
There is nothing magic in that : it just works by rewriting fragmented files. But it has some heuristics that could make it more efficient than other tools, including defrag and, maybe, xfs_fsr.
As root, call shake my_dir, and go do something usefull or pleasant until it complete. Then my_dir should be less fragmented.
For better results, you should call Shake on the whole partition, when you're not using it.
If you just wanted to see the fragmentation, call shake --pretend --verbose --verbose my_dir, alias shake -pvv my_dir.
