short read could happen for aio when: we are reading cross the stripe layout lock got cancelled on client before we continue to next stripe in cl_io_loop() vvp_io_read_start()->can_populate_pages() sees the layout has changed, marks the io needs to be restarted. ll_file_io_generic failed to restart io as the return code from cl_io_loop() is EIOCBQUEUED. |
