I have a CIFS mount that was working but has broken. It still mounts with sudo mount -a but not at boot. The CIFS share is hosted on openmediavault 5 on a raspberry pi 4. I'm not seeing any errors in the OMV logs.

My fstab entry looks like this:

//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 output looks like this:

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 output looks like this:

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.

Any help would be hugely appreciated. Thanks!

Your fstab entry looks okay and should work fine.

It ,however. appears that the mount is attempted prior to network connectivity becomes available ( systemd's connectivity in particular ). Hence these errors:

CIFS VFS: Error connecting to socket. Aborting operation.

and

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.

This is due to the service systemd-networkd-wait-online being disabled.

Enable the service like so:

sudo systemctl enable systemd-networkd-wait-online

This should execute without errors.

After that reboot your system. Your network share should mount at boot now.

If the share is still not mounting, check:

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

And see if either service is disabled and enable them too. Then reboot your system.

I too was having exact same issue. Though in my case CIFS share is hosted on ASUS RT AC68U with DD WRT 3.0

Here's how I solved the issue:

(1) Enabled these services (as I've disabled these in the past):

sudo systemctl enable systemd-networkd-wait-online

sudo systemctl enable systemd-networkd.service


sudo systemctl enable NetworkManager-wait-online.service

Note: If any of those services are masked, then you would need to first unmask, and then enable it.

You can find more on how to properly unmask here: [1] and [2].

(2) I commented out (removed) fstab entry for CIFS share, and created systemd mount for cifs share:

Note: Create a new file media-admn-nas.mount in the diretory /etc/systemd/system.

The filename must contain the mount point name where the slashes are replaced with “minus”. Mount-directory /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

Note-1: In my case, media-admn-1\x2d6TB.mount is an additional hard drive where I have mounted the cifs share, so I've added that as After= requirement.

Note-2: As I was still getting errors, I've added TimeoutSec=15

(3) Enable the mount:

sudo systemctl enable media-admn-nas.mount

sudo systemctl daemon-reload

(4) Reboot: 15 sec after a reboot, CIFS share should be mounted.

(5) Check status:

$ 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)
