NFS 服务器守护程序在启动时无法启动

NFS 服务器守护程序在启动时无法启动

我正在尝试导出外部磁盘，因此，我将 nfs-server 服务配置为等待 disk1 挂载，但失败了。

这是开机之后的情况：

$ systemctl status nfs-server.service
● nfs-server.service - NFS server and services
   Loaded: loaded (/etc/systemd/system/nfs-server.service; enabled; vendor preset: enabled)
   Active: failed (Result: exit-code) since Sun 2020-04-26 14:46:28 CEST; 3min 7s ago
  Process: 307 ExecStartPre=/usr/sbin/exportfs -r (code=exited, status=1/FAILURE)
  Process: 312 ExecStopPost=/usr/sbin/exportfs -au (code=exited, status=0/SUCCESS)
  Process: 314 ExecStopPost=/usr/sbin/exportfs -f (code=exited, status=0/SUCCESS)

abr 26 14:46:28 raspberrypi systemd[1]: Starting NFS server and services...
abr 26 14:46:28 raspberrypi exportfs[307]: exportfs: Failed to stat /media/pi/disk1: No such file or directory
abr 26 14:46:28 raspberrypi systemd[1]: nfs-server.service: Control process exited, code=exited, status=1/FAILURE

abr 26 14:46:28 raspberrypi systemd[1]: Failed to start NFS server and services.

如果我重新启动服务它就能顺利运行

$ sudo systemctl restart nfs-server.service
$ systemctl status nfs-server.service
● nfs-server.service - NFS server and services
   Loaded: loaded (/etc/systemd/system/nfs-server.service; enabled; vendor preset: enabled)
   Active: active (exited) since Sun 2020-04-26 14:59:51 CEST; 4s ago
  Process: 943 ExecStartPre=/usr/sbin/exportfs -r (code=exited, status=0/SUCCESS)
  Process: 944 ExecStart=/usr/sbin/rpc.nfsd $RPCNFSDARGS (code=exited, status=0/SUCCESS)
 Main PID: 944 (code=exited, status=0/SUCCESS)

abr 26 14:59:51 raspberrypi systemd[1]: Starting NFS server and services...
abr 26 14:59:51 raspberrypi systemd[1]: Started NFS server and services.

我将服务配置为“需要”和“之后” disk1 挂载，但它不起作用：

# /etc/systemd/system/nfs-server.service
[Unit]
Description=NFS server and services
DefaultDependencies=no
Requires=network.target proc-fs-nfsd.mount media-pi-disk1.mount
Requires=nfs-mountd.service
Wants=rpcbind.socket
Wants=nfs-idmapd.service

After=local-fs.target media-pi-disk1.mount
After=network.target proc-fs-nfsd.mount rpcbind.socket nfs-mountd.service
After=nfs-idmapd.service rpc-statd.service
Before=rpc-statd-notify.service

要求提供额外信息：


$ systemctl status media-pi-disk1.mount

答案1

我让系统自动安装磁盘。我刚刚按照 Gerald 的问题配置了磁盘安装/etc/fstab，它就正常工作了！非常感谢你们。

答案2

我遇到了 nfs 服务器守护进程在启动过程中失败的错误问题。我不知道具体原因，但问题出在 LVM 上。在重启之前，我删除了我的 LV、VG 和 PV。我通过将它们添加到 来使挂载永久化。从我的问题/etc/fstab中删除我的 PV 引用后，问题解决了。/etc/fstab
