考虑以下/etc/exports：
/verbatim 192.168.0.0/255.255.255.0(rw,sync,no_subtree_check)
/sandisk 192.168.0.0/255.255.255.0(rw,sync,no_subtree_check)
/verbatim并且/sandisk是外部硬盘的挂载点，定义/etc/fstab如下：
/dev/disk/by-uuid/06b24834-a749-4d93-b0d5-a6da71eaf224 /verbatim ext4 defaults 0 1
/dev/disk/by-uuid/d7dbea69-0332-4d12-b905-b9a116e28422 /sandisk ext4 defaults 0 1
现在，如果任何硬盘无法挂载（例如，当硬盘关闭或拔出时），NFS 服务器将无法启动。我认为日志中的相关条目如下：

有什么方法可以配置 NFS 服务器来启动并为其他驱动器（sandisk）提供服务，即使某些驱动器无法安装（逐字）？
答案1
mountpoint将或选项添加mp到您的 /etc/exports。这将 1) 阻止 nfs-server-generator 为该路径添加 systemd 依赖项，以及 2) 在将exportfs文件系统标记为导出之前验证它是否已挂载。
（可以使用 查看自动生成的依赖项systemctl cat nfs-server，并在末尾显示额外的文件“order-with-mounts.conf”，并使用 进行刷新systemctl daemon-reload。）
