【问题描述】：

每当 USB 驱动器连接到计算机时，我都想执行“mount -a”。我在文件'/etc/udev/rules.d/85-my_rule.rules'中创建了一个简单的规则：

SUBSYSTEM=="block", RUN+="/bin/mount -a"

如果我手动调用“sudo mount -a”，一切正常。使用 'dmesg' 我还可以看到我的驱动器：

块设备也在那里，但似乎没有执行规则。我该怎么办？我正在使用 Ubuntu Server 20.04 LTS。

【问题讨论】：

您是否将 USB 驱动器添加到 /etc/fstab？我不是mount -a 不会挂载你的U盘

标签： ubuntu mount udev

【解决方案1】：

也许您需要在规则中添加ACTION，例如：

 SUBSYSTEM=="block", ACTION=="add", RUN+="/bin/mount -a"
