Here's a step-by-step guide that might help you achieve your goal of getting Plex to access external drives:

Step 1: Export the Working Plex Docker Container
Export the Container:
First, you'll need to export your existing Plex container from UGOS. This usually involves stopping the container and using Docker commands to save it as a tar file. The command might look something like this:
bash
Copy code
docker export plex_container_name -o /path/to/save/plex_backup.tar
Step 2: Connect Your External HDDs
Connect the DAS:
Physically connect your USB or Thunderbolt DAS to the NAS. Ensure that UGOS Pro recognizes the drives, even if they aren't yet accessible over the network.
Step 3: SSH into the NAS and Discover Drives
SSH into the NAS:

You'll need to SSH into the NAS using a terminal application. You can do this from your computer with a command like:
bash
Copy code
ssh username@nas_ip_address
Replace username with your NAS user account name and nas_ip_address with the IP address of your NAS.
List the Drives:

Use the following command to list all connected drives:
bash
Copy code
lsblk
This will show you all the block devices, including your internal drives and the external DAS.
Step 4: Mount the External Drives
Mount the External Drives:
You may need to manually mount the external drives if they aren't automatically mounted. You can create a mount point (e.g., /mnt/external_drive) and then mount the drive with a command like:
bash
Copy code
sudo mount /dev/sdX1 /mnt/external_drive
Replace /dev/sdX1 with the appropriate device name for your external drive as found in the lsblk output.
Step 5: Edit the Plex Docker Container
Edit the Docker Container:
You'll need to modify the Docker container to include a volume pointing to your mounted external drive. If you’re using Docker Compose, you can add a volume like this:
yaml
Copy code
version: '3'
services:
  plex:
    image: plex_image_name
    volumes:
      - /mnt/external_drive:/media
If you’re using Docker directly, you can start a new container with a similar command:
bash
Copy code
docker run -d --name=plex -v /mnt/external_drive:/media plex_image_name
Step 6: Set Permissions
Set Proper Permissions:
Make sure that Plex has read/write permissions for the external drives. You can do this with:
bash
Copy code
sudo chown -R plex_user:plex_group /mnt/external_drive
sudo chmod -R 755 /mnt/external_drive
Replace plex_user and plex_group with the correct user and group that Plex runs under on your NAS.
Step 7: Restart Plex
Restart the Plex Container:
Once everything is set up, restart your Plex container. The new configuration should allow Plex to access the files on your external DAS.
