CIFS 挂载问题,错误 cifs_mount 失败,返回代码 = -2

CIFS 挂载问题,错误 cifs_mount 失败,返回代码 = -2

我有一个 CIFS 安装,以前可以工作,但现在坏了。它仍然可以安装,sudo mount -a但不会在启动时安装。CIFS 共享托管在 raspberry pi 4 上的 openmediavault 5 上。我没有在 OMV 日志中看到任何错误。

我的 fstab 条目如下所示:

//192.168.1.97/sharedrive /media/Nas cifs credentials=/home/brad/.smbcredentials,vers=3,_netdev,iocharset=utf8,auto,forceuid,forcegid,uid=1000,gid=5000,file_mode=0777,dir_mode=0777 0 0

DMESG 输出如下所示:

CIFS: Attempting to mount //192.168.1.97/sharedrive
CIFS VFS: Error connecting to socket. Aborting operation.
CIFS VFS: cifs_mount failed w/return code = -2

JOURNALCTL 输出如下所示:

systemd[1]: media-Nas.mount: Mount process exited, code=exited, status=32/n/a
systemd[1]: media-Nas.mount: Failed with result 'exit-code'.
systemd[1]: Failed to mount Mount CIFS Share.

任何帮助都将不胜感激。谢谢!

答案1

您的fstab条目看起来不错并且应该可以正常工作。

然而,似乎在网络连接可用之前就尝试了挂载(systemd 的连接性)因此出现以下错误:

CIFS VFS:连接套接字时出错。中止操作。

systemd[1]: media-Nas.mount: 挂载进程已退出,代码=已退出,状态=32/n/a systemd[1]: media-Nas.mount: 失败,结果为“退出代码”。systemd[1]: 无法挂载 CIFS 共享。

这是因为该服务systemd-networkd-wait-online已被禁用。

像这样启用服务:

sudo systemctl enable systemd-networkd-wait-online

这应该不会出现错误。

之后重启系统。你的网络共享现在应该会在启动时挂载。

如果共享仍未安装,请检查:

systemctl status networkd-dispatcher.service systemd-networkd.service

看看是否有服务被禁用,并启用它们。然后重新启动系统。

答案2

我也遇到了同样的问题。虽然我的情况是 CIFS 共享托管在带有 DD WRT 3.0 的 ASUS RT AC68U 上

以下是我解决问题的方法:

(1)启用这些服务(因为我过去已经禁用了这些服务):

sudo systemctl enable systemd-networkd-wait-online

sudo systemctl enable systemd-networkd.service

sudo systemctl enable NetworkManager-wait-online.service

注意:如果其中任何服务是masked,那么您需要先unmask,然后启用它。

您可以在这里找到有关如何正确操作的更多信息unmask[1][2]

(2)我注释掉(删除)了fstabCIFS 共享的条目,并systemd mount为 cifs 共享创建了条目:

注意:在目录中创建一个新文件 media-admn-nas.mount /etc/systemd/system

文件名必须包含挂载点名称,其中斜杠替换为“减号”。挂载目录/media/admn/nas => media-admn-nas.mount

sudo nano /etc/systemd/system/media-admn-nas.mount

[Unit]
Description=CIFS Mount Service 
Requires=network-online.target systemd-networkd.service
After=network-online.target network-online.service media-admn-1\x2d6TB.mount remote-fs.target
Wants=network-online.target NetworkManager-wait-online.service

[Mount]
What=//192.168.1.1/nas
Where=/media/admn/nas
Options=rw,_netdev,auto,cache=none,vers=3.11,credentials=/home/admn/.smbcredentials,forceuid,forcegid,uid=1000,gid=1000
Type=cifs
TimeoutSec=15

[Install]
WantedBy=multi-user.target

注 1:就我而言,media-admn-1\x2d6TB.mount是一个安装了 cifs 共享的附加硬盘,因此我将其添加为After=要求。

注 2:由于我仍然遇到错误,因此我添加了TimeoutSec=15

(3)启用挂载:

sudo systemctl enable media-admn-nas.mount

sudo systemctl daemon-reload

(4)重新启动:重新启动 15 秒后,CIFS 共享应该已挂载。

(5)检查状态:

$ systemctl status media-admn-nas.mount
● media-admn-nas.mount - CIFS Mount Service
     Loaded: loaded (/etc/systemd/system/media-admn-nas.mount; enabled; vendor preset: enable>

      Tasks: 0 (limit: 19083)
