FAQ

• How do I change the size of the virtual disk?

  By default it is 16GB, but you can modify the DISK_SIZE setting in your compose file:

  environment:
      DISK_SIZE: "16G"
  

  To create an empty disk with a maximum capacity of 8 terabyte you would use a value of "8T" for example.

• How do I change the location of the virtual disk?

  By default it resides inside a docker volume, but you can add these lines to your compose file:

  volumes:
      - /home/user/data:/storage
  

  Just replace /home/user/data with the path to the folder you want to use for storage.

• How do I install a specific version of vDSM?

  By default it installs vDSM 7.2, but if you want to use an older version you can add its URL to your compose file:

  environment:
     URL: "https://global.synologydownload.com/download/DSM/release/7.0.1/42218/DSM_VirtualDSM_42218.pat"
  

  You can also switch back and forth between versions this way without loosing your file data.

• What are the differences compared to standard DSM?

  There are only three minor differences: the Virtual Machine Manager package is not available, Surveillance Station does not include any free licenses, and logging in to your Synology account does not work.
