Archlinux nfs 立即关闭

我想设置一个 NFS 服务器，所以我在Archlinux 教程中设置 NFS，有两个挂载点：

[jenia@jenia ~]$ sudo exportfs -arv
point 1
point 2
point 3
exportfs: /etc/exports [3]: Neither 'subtree_check' or 'no_subtree_check' specified for export "192.168.1.0/24:/srv/nfs".
  Assuming default behaviour ('no_subtree_check').
  NOTE: this default has changed since nfs-utils version 1.0.x

exportfs: /etc/exports [4]: Neither 'subtree_check' or 'no_subtree_check' specified for export "192.168.1.0/24:/srv/nfs/music".
  Assuming default behaviour ('no_subtree_check').
  NOTE: this default has changed since nfs-utils version 1.0.x

exporting 192.168.1.0/24:/srv/nfs/music
exporting 192.168.1.0/24:/srv/nfs

但没有任何回应nfs://192.168.1.0/srv/nfs：

[jenia@jenia ~]$ sudo nfs-ls nfs://192.168.1.0/srv/nfs
Failed to mount nfs share : nfs_mount_async failed. Failed to start connection. Failed to start connection. connect() to server failed. Network is unreachable(101)
[jenia@jenia ~]$

当我这样做journalctl --follow -xn并重新启动 nfs 守护程序时systemctl restart nfs-server.service，我得到：

Nov 17 20:36:21 jenia sudo[45585]: pam_unix(sudo:session): session opened for user root(uid=0) by jenia(uid=0)

一切systemctl status nfs-mountd nfsdcld nfs-idmapd都在成功运行。

做事systemctl status nfs-server说：

[jenia@jenia ~]$ sudo systemctl status nfs-server.service

有人知道我在做什么错吗？
