我在新安装的 Raspberry Pi Model B+ 上运行 Raspbian Jessie。我几个小时前使用过apt-get update，apt-get upgrade系统应该是最新的。
我正在尝试安装连接到我的 AVM Fritz!Box 的 USB 磁盘。为此，我将其添加到我的 /etc/fstab 中
//192.168.178.1/FRITZ.NAS/VBTM-Store-n-Go-01 /home/pi/fb cifs username=myuser,password=mypass,workgroup=WORKGROUP,users,auto,user_xattr 0 0
重新启动 Raspberry Pi 后，USB 磁盘未安装到我的 /home/pi/fb 目录。
Asudo mount -a立即解决了这个问题，我可以访问 USB 磁盘。
我查看了一下dmesg，发现几个标记为红色的条目。其中一些似乎解决了这个问题：

为什么 Raspbian 在启动时忽略 fstab？
答案1
我将“noauto,x-systemd.automount”添加到 fstab 中的挂载选项中，就像“DavidCWGA”建议的那样：https://github.com/raspberrypi/linux/issues/824
现在为我工作！
