When you create a Lustre file system, by default it puts your data on one OST. Check out
section 18.3 (lfs setstripe) in the latest Lustre manual for information on how to change
this for a single file, a single directory tree, or the whole filesystem

When I run the iozone benchmark on lustre it ends up only using one OSS server, I assume
this has something to do with the way it writes but I'm not really sure where to look,
at the moment I am just using automated tests...
(iozone -Ra -g 64G)
lustre is functioning fine and when using dd from multiple machines with a bs=102400 it
uses all OSS.
Any pointers would be very welcome...
