[lustre-discuss] OSS Large File I/O using O_DIRECT

[John Bauer]

Hello all,

Is the a way to determine what size a client I/O request must be to 
trigger the OSS to use the Large File ( non-buffered ) I/O path?  Is 
this configurable?

Is there a way for a client-side application to trigger this behavior 
independent of the I/O size?
