      It would be valuable to programmatically discover the number of OSTs that are available. An llapi_* function would be a suitable place for this call.

      Use Case

      When writing HDF5 files one typically configures the number of writers as a fraction of the number of OSTs for best performance.

      Currently this information is only available by writing a file with stripe count set to -1 and then counting the number of stripes present. A programmatic interface to the OST count would simplify this task.
