When is a good time to defrag? Is it something I should cron (hourly? Daily?)

Files on our gluster infrastructure are going to be changing very often (xen
sparse image files), and the last thing I want is a brick to become full, and
having to take down VM's to distribute them to a less occupied brick.
Defrag is only run when you are expanding existing subvolumes for
distribute. Expansion has a caveat since the directories will not be
distributed unless "scale-n-defrag" is run. But the files newly created
in new directories will be redistributed properly, it is just for the
older directories it won't happen. (Directories i mean "top level"
directories).
