I am running an n8n deployment. I've only been learning this for about 2 weeks so have a minor grasp on this right now. Somehow I maxed out my mine-volume today, up to 400Mb. I don't know how to clear or empty it. ChatGPT keeps telling me to use the Railway CLI, but there is none that I can find. I have emptied out all of my n8n executions on my n8n instance hosted on railway, and when I did that, my production deployment crashed and postgres crashed. How that my storage is so full I think it's causing big issues to redeploy as it keeps crashing. I'm worried that if I wipe the volume it will wipe my worfklows and credentials, which I really need.
