2019-06-06 09:26:41 [72389.747032] LustreError: 10999:0:(osc_request.c:1076:check_write_rcs()) Unexpected # bytes transferred: 0 (requested 16777216)

            req->rq_bulk->bd_nob_transferred != requested_nob) {

        return (rc == -EIO || rc == -EROFS || rc == -ENOMEM ||
                rc == -EAGAIN || rc == -EINPROGRESS);
}

This error is not recoverable and fail the IO.
It looks like reply came for original request while we are resending it. So request has a reply, but bulk has 0 bytes.
The patch https://review.whamcloud.com/#/c/32905 fix the issue, but original ticket is closed. So I resubmitting to this https://review.whamcloud.com/#/c/35571
