CIFS mount problem, error cifs_mount failed w/return code = -2
Solution 1
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

Solution 2
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 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!

Admin about 3 yearsPlease edit your question to add the output of
systemctl status NetworkManager-wait-online.service systemd-networkd-wait-online
. Your fstab entry looks okay but those two services might be disabled one or both. -
Admin about 3 yearsPleas add the output of
systemctl status networkd-dispatcher.service systemd-networkd.service
to your question. -
Admin about 3 years@tracing-shadows Please go through the answer I've just posted, it might work out for you too:
https://askubuntu.com/a/1312383/928088
. Thanks. -
Admin over 2 yearsI had the same issue and my setup is also OMV 5 with Raspi4. I found a solution on Raspberry forum for this issue and it worked. Reliable Wait for Network Note: the original code did not work, but modified code by Paul92 did the trick. Hope this helps

tracing_shadows about 3 yearsThanks for your help. After enabling the service the share is not mounting at boot, with the
dmesg
output the same. -
Raffa about 3 years@tracing_shadows Can you please verify the service has been enabled and run again
systemctl status systemd-networkd-wait-online
. Also please add the output of that to your question. -
tracing_shadows about 3 yearsI've updated the post to show the current output.

Raffa about 3 years@tracing_shadows Pleas add the output of

Raffa about 3 years@tracing_shadows Those two services are enabled and running.
systemd-networkd-wait-online
has been fixed and is now running.NetworkManager-wait-online.service
does not complain and runs in a timely proper manner.fstab
entry looks fine. I am out of thought. What I am sure of is that it is a connectivity issue and systemd's.in particular. -
tracing_shadows about 3 yearsThank you for troubleshooting with me. It was greatly appreciated.

Jags about 3 years@raffa I too am having exact same issue as @tracing-shadows. Though my
fstab
entry do not have this_netdev,iocharset=utf8,forceuid,forcegid,file_mode=0777,dir_mode=0777
Should I add that... as after enablingsystemd-networkd-wait-online
andsystemd-networkd.service
, I'm getting these errors (too long for a comment):https://pastebin.com/raw/eGqZ8HUQ
. My fstab://192.168.1.1/nas /media/admn/nas cifs auto,vers=3.11,credentials=/home/admn/.smbcredentials,uid=1000,gid=1000,noperm 0 0

Jags about 3 years@raffa Thank you so much. Adding
_netdev
tofstab

UzUmAkI_NaRuTo about 3 years@tracing_shadows were you able to solve this? Facing exact same issue on Ubuntu Server 20.04. All services are enabled but nothing works.
