Unable to mount CIFS share on boot with fstab in LinuxMint 19 [SOLVED]

[ladon]

Hi All,

I installed Linux Mint 19 x64 Cinnamon (no update from a previous version).
I entered the following line in my fstab:

//<NasIP>/<share> /media/pictures cifs credentials=/home/<user>/.credentials,rw,uid=1000,gid=1000,nounix,vers=1.0,iocharset=utf8,file_mode=0777,dir_mode=0777 0 0

This line works perfectly fine on my very old Lubuntu Netbook Remix system.
In Linux Mint 19 it doesn't map the shares on boot.
When I select the share in my file manager I receive the following error:
"Unable to mount. Operation permitted for root only"

I tried this with a normal user as well as with an admin user.
If I enter "sudo mount -a", it maps all the shares correctly.

Maybe worth mentioning that "mount -a" returns only the message that only root can execute it.
However, this message is the same on my Lubuntu system. So I don't think that's connected with it.
The share itself resides on a very old QNAP NAS box (TS-109).

The file permissions for fstab are set to "read" to everyone.
Even when I add "write" to everyone, it doesn't change the behaviour.

Any thoughts about this are very much appreciated.
Many thanks in advance.

Kind Regards,
Andreas

A couple of suggestions and it depends on why you want this share mounted at boot.

[1] If you want this to mount as required change your fstab mount to this:

//<NasIP>/<share> /media/pictures cifs credentials=/home/<user>/.credentials,rw,uid=1000,gid=1000,nounix,vers=1.0,iocharset=utf8,file_mode=0777,dir_mode=0777,user,noauto 0 0

Your share will not mount at boot or at login. It will mount when you select the "pictures" icon on the side panel of your file manager. Note: this will only work as described if your mount point is under /media ( which it is in your case ) or under your home directory ).

[1a] You can add the following to your Startup Applications ( Menu > Startup > Applications > + ):

Code: Select all

mount /media/pictures

Then it will mount at login not at boot.

[2] If you truly want it to mount at boot not "as required" or at login keep your fstab line as it is but:

** Create a new file at /etc/network/if-up.d/fstab
** With this content:

Code: Select all

#!/bin/sh
mount -a

** Make it executable:

Code: Select all

sudo chmod +x /etc/network/if-up.d/fstab

Something in if-up.d will run only after your network stack is operational on your Mint system which is why I suspect the orginal fstab line if not working.

Awesome!
That has solved my problem.
I added the "user,noauto" to the entries and that works perfectly fine.

Thank you very much for replying to that question and sharing your knowledge.
Very helpful indeed!

Kind Regards
