我有一个 NAS 设备,并通过以下条目在其上挂载了几个目录/etc/fstab
:-
# NFS
number0:/projects /home/carl/number0/projects nfs rw 0 0
number0:/carl /home/carl/number0/stuff nfs rw 0 0
number0:/Qmultimedia /home/carl/Music nfs rw 0 0
number0:/Photos /home/carl/Pictures nfs rw 0 0
最近(可能是自从更新以来,虽然我不确定),NFS 共享在启动时没有安装,我必须使用 来安装它们sudo mount -a
。
由于我自 Ubuntu 10.04(可能更早)以来一直使用相同的 fstab 条目,我怀疑 fstab 标准发生了一些变化,我不再遵守。
AU 上有很多关于 NFS 无法自动挂载的问题,但都与较旧的 Ubuntu 版本有关,除了这个,这似乎不相关。

NFS 服务器是 number0,它一直在运行(我还有另一台机器也连接到同一个 NFS 共享)。
carl@number2:~$ ping number0
PING number0.home (192.168.1.65) 56(84) bytes of data.
64 bytes from number0.home (192.168.1.65): icmp_seq=1 ttl=64 time=0.364 ms
编辑 2:@waltinator 要求我检查这些目录的存在和权限
carl@number2:~$ ls -l /var/lib | grep nfs
drwxr-xr-x 5 statd nogroup 4096 Jul 21 17:55 nfs
carl@number2:~$ ls -l /var/lib/nfs | grep v4recovery
drwxr-xr-x 2 root root 4096 Apr 27 23:05 v4recovery
编辑:共享实际上出现在 Nautilus 中,但未被安装。
答案1
您是否尝试过将服务器名称(number0)更改为 IP(192.168.1.65)?
看起来,在挂载时名称解析存在问题。
例如从以下更改:
number0:/projects /home/carl/number0/projects nfs rw 0 0
到
192.168.1.65:/projects /home/carl/number0/projects nfs rw 0 0
答案2
都怪 systemd。很可能是最近更新导致的。需要明确告知它等待网络准备就绪后再尝试挂载。
systemctl enable NetworkManager-wait-online.service
很好的解释这里。
