无法结帐会话，因为发生了产生错误

Question

我的网站目前正在制作中，我不知道发生了什么。

这是我的nginx conf：

server {
  listen 80;
  server_name www.joinery.nyc joinery.nyc;
  root /data/joinery.nyc/current/public;
  passenger_enabled on;

  return 301 https://joinery.nyc$request_uri;
}

server {
  listen 443;
  server_name www.joinery.nyc joinery.nyc;

  ssl    on;

  ssl_certificate    /opt/nginx/conf/joinery.nyc.crt;
  ssl_certificate_key    /opt/nginx/conf/joinery.nyc.key;


  location /attachments {
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header X-Forwarded-Proto https;
     proxy_set_header Host $http_host;
     proxy_ignore_headers Set-Cookie;
     proxy_hide_header Set-Cookie;
     proxy_redirect off;
     proxy_pass http://127.0.0.1:81/attachments;
     proxy_cache images;
     proxy_cache_valid 200 30d;
     proxy_cache_bypass $http_x_proxy_uncache;
   }  
   location / {
     proxy_set_header X-Real-IP $remote_addr;
     proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
     proxy_set_header X-Forwarded-Proto https;
     proxy_set_header Host $http_host;
     proxy_redirect off;
     proxy_pass http://127.0.0.1:81/;
   }
}

server {
    listen 81;
    server_name joinery.nyc;

    root /data/joinery.nyc/current/public;

      passenger_enabled on;
      rack_env production;
      passenger_min_instances 2;

    location ~ ^/assets/ {
      expires 1y;
      add_header Cache-Control public;
      # to serve pre-gzipped version, requires nginx compiled with this
      gzip_static on;

      # Some browsers still send conditional-GET requests if there's a
      # Last-Modified header or an ETag header even if they haven't
      # reached the expiry date sent in the Expires header.
      add_header Last-Modified "";
      add_header ETag "";
      break;
    }
}

当我检查/opt/nginx/logs/error.log下的错误日志时，我收到以下消息：

2018/01/05 11:47:48 [alert] 10909#0: *3 write() to "/opt/nginx/logs/access.log" failed (28: No space left on device) while logging request, client: 127.0.0.1, server: joinery.nyc, request: "GET /import/facebook/a?referral=AV4 HTTP/1.0", upstream: "passenger:/tmp/passenger.1.0.10889/generation-0/request", host: "joinery.nyc", referrer: "http://m.facebook.com"

仅供参考：这一切都是在我尝试将CDN添加到我的应用程序（Cloudfront）之后开始的。我修改了我的nginx Web服务器以启用跨源请求，但随后又恢复了更改，因为我认为这是我的网站关闭的问题。但仍然下来，不知道
