[HPDD-discuss] how to access the data in a given OST directly

Hi, If I have known a piece of data resides in a given OSS/OST. Is it possible to access it directly with using lustre client ? To be specific, the problem is when I am on an OSS/OST, I want to access the local data of this OSS/OST without referring to lustre client. Is it possible, how can I achieve that ? Thanks in advance.
