How do I change values like wallet address or storage capacity?

1. Stop and remove the running Storage Node Docker container (CLI) or stop the service (GUI Windows):

CLI Install
GUI Windows Install
CLI Install
docker stop -t 300 storagenode
docker rm storagenode
GUI Windows Install

Elevated PowerShell:

Stop-Service storagenode

Or click the "Stop" button in the Windows Services applet on "Storj V3 Storage Node" service

2. Run your Storage Node again after editing needed parameters:

CLI Install
GUI Windows Install
CLI Install

Parameters are described in the article Storage Node concepts

How to run your Storage Node with modified parameters from the CLI: Running Storage Node

GUI Windows Install

Open the config file "%ProgramFiles%\Storj\Storage Node\config.yaml" with a text editor (we recommend to use Notepad++, as the regular Notepad will not work) and modify needed parameters. Save the configuration file and restart the Storj V3 Storage Node service.

Or in the elevated PowerShell:

Restart-Service storagenode
