There is a library "liblustreapi" that has C function interfaces for creating files with specific stripe parameters - llapi_file_open() is the most basic interface that allows open/create of a file and setting the stripe count, stripe size, and starting OST index. A more complete interface is llapi_file_open_param() that lets the application specify more parameters for the layout.
