Error when applying remote mount SMB share from a Synology NAS

MilesTEG1 · Feb 10th 2026

Hello,

I'm triyng to mount a remote smb share from my Synology NAS under OMV Storage → Remote Mounts

But I can't apply those settings, because of the error bellow :

Code

Failed to execute command 'export PATH=/bin:/sbin:/usr/bin:/usr/sbin:/usr/local/bin:/usr/local/sbin; export LC_ALL=C.UTF-8; export LANGUAGE=; omv-salt deploy run --no-color remotemount 2>&1' with exit code '1': debian:
----------
...

Here the settings I set:

I confirm that the User/Password works fine on another system, and the options are the one I used on a LXC Proxmox to mount some shares from this Synology NAS.

How can I fix this error?

Thanks in advance,

Have a nice day.

Ps: the log given in OMV UI part1:

The output tells you to look at journalctl for more info.

I would look at the output of:

sudo journalctl -u srv-remotemount-Syno_Backup_OMV_Asustor.mount -b

Hello 👋🏻

I wanted to get back here but with my work I totally forgot…

I spent severals hours to find the problem…

I used Claude and Gemini for help, and we pointed the kernel but finally it wasn’t this …

Why the kernel because the exact same mount command worked and still works fine in a Debian 13 VM with an older kernel with another cifs module…

But with downgrading the kernel version the mount command still doesn’t worked…

And it was a suggestion of Gemini that solved the problem here…

He suggests me to look at the autoblocking in DSM (Synology)…

And that was it !

Crap! 3 hours loosed because of this f#%$*¥£ DSM auto blocking 😅

Because the IP of the OMV NAS was indeed blocked by DSM and I don’t know when nor why 😅

This post can be marked as solved

Sorry for the inconvenience of my request 😇
