启动期间无法挂载 NFS 远程共享

我正在尝试在 Ubuntu 16.04 启动时挂载目录。我按照本教程中提到的确切步骤进行操作关联。我能够手动挂载和卸载文件夹。

正如教程中提到的，我也对 /etc/fstab 进行了更改，但不幸的是，当我启动系统时自动挂载失败了。

还尝试了手动安装并且两者都运行良好。

sudo mount -a
sudo start nfs-home.mount

/etc/fstab

nth@nthYOGA:~$ cat /etc/fstab
# /etc/fstab: static file system information.

我遇到了同样的问题。通过将 更改auto为 来x-systemd.automount,noauto 修复此问题/etc/fstab。

例子：

192.168.178.42:/disk1/data /media/data nfs nouser,rsize=32768,wsize=32768,atime,x-systemd.automount,noauto,rw,dev,noexec,suid 0 0

从systemd.mount（5）：

x-systemd.automount

将为文件系统创建一个自动挂载单元。请参阅systemd.自动挂载(5)了解详情。
