SharedFolderMountScript

This is a simple script for people like me who have had problems with network shared folders connected when using Sonarr, Radarr or client torrents like Deluge and qBittorrent. In particular in my case these applications are run on docker containers managed by CasaOS.

Unfortunately, however, there were several problems with folder permissions, as they all seem to belong to the root user.

My goal is to directly download files into the /Download folder of Synology connected to casaOS using Deluge and qBittorrent, and then move them with Sonarr and Radarr to the /Movies and /TV folders within the NAS, which are monitored by Plex. I've tried various solutions, such as:

  • I attempted to use PUID set to 0, which works with Deluge but not with qBittorrent. The latter requires PUID set to 1000; otherwise, an error occurs, and the interface doesn't even open via the browser.
  • I tried downloading the files to the internal HDD with both torrent clients in the DATA/Downloads folder, which didn't pose any problems. However, I'm experiencing slowness when subsequently transferring files to the NAS folder. I don't understand why it takes about 50 minutes for a 36 GB file.
  • I also attempted to change the folder permissions, but I wasn't successful in changing the owner from root to the casaOS user.

So I decided to write this very basic and simple script that would allow me to correctly mount the shared folders on those of casaOS with user permissions in order to avoid all the problems indicated above. This script starts automatically at system startup before the containers are started so as not to create problems when they start.

NOTE: Verify that samba is installed correctly.

BASIC INFO

The script was designed to mount 3 different folders in three different places. One folder for downloads and 2 for different types of media but you can add and remove as many mounts as you want by making the necessary changes.

PREPARE THE SCRIPT

Modify the script as follows:

  • Change IP-ADDRESS with the IP address of the folder to mount and PATH with the path of the folder to mount
  • Change PATH-TO-MOUNT with the path of the local folder in which to mount the remote folder
  • Change USERNAME-HERE and PASSWOR-HERE to the correct samba account username and password

For example, suppose that: the remote IP is 127.1.1.1 and the remote folder path is /Downloads. The local path is /DATA/Downloads. And the account to log in via samba has the username admin and the password pswd.

Then the first line of mount will have to be modified as follows:

BEFORE

sudo mount -t cifs [//IP-ADDRESS/PATH] [/PATH-TO-MOUNT default: /DATA/Downloads] -o username=[USERNAME-HERE],password=[PASSWORD HERE],vers=3.0,rw,uid=1000,gid=1000,forceuid,forcegid,file_mode=0777,dir_mode=0777,nounix

AFTER

sudo mount -t cifs //127.1.1.1/Downloads /DATA/Downloads -o username=admin,password=pswd,vers=3.0,rw,uid=1000,gid=1000,forceuid,forcegid,file_mode=0777,dir_mode=0777,nounix

Now that the basic changes have been made to the script we can proceed with its execution.

START THE SCRIPT AT BOOT

To start the script at system startup, a couple of steps are enough.

  • Save the script to an appropriate location on your system, such as /usr/local/bin/mounter.sh, and make it executable with the command sudo chmod +x /usr/local/bin/mounter.sh
  • Create a service file called mounter.service in /etc/systemd/system/: sudo nano /etc/systemd/system/mounter.service
  • Inside this file, insert the following content:
[Unit]
Description=Mount Retry Script

[Service]
Type=oneshot
ExecStart=/usr/local/bin/mounter.sh

[Install]
WantedBy=multi-user.target
  • enable the service to start during boot: sudo systemctl enable mounter.service

Now when the system starts the folders will be mounted automatically and if the process fails the system will continue to make an attempt every 30 seconds.
