[HPDD-discuss] llapi_file_get_stripe arguments

I am using the llapi_file_get_stripe() function. The second arguement is struct lov_user_md_v1 { __u32 lmm_magic; __u32 lmm_pattern; __u64 lmm_object_id; __u64 lmm_object_seq; __u32 lmm_stripe_size; __u16 lmm_stripe_count; __u16 lmm_stripe_offset; struct lov_user_ost_data_v1 lmm_objects[0]; } How do I indicate to the kernel how many elements are in the lmn_objects[] array? Or, How do I know how large to make the array? What is the largest number of OST's that a file can be striped across? Thanks John
