Need Help Removing Node from Proxmox Cluster

[suhaib]

Hello Proxmox Community,

I hope this post finds you well. I'm currently facing an issue with my Proxmox setup, and I'm seeking advice on how to gracefully remove a node from a Proxmox cluster.

Issue Summary: I accidentally created a Proxmox cluster with only one node, and now I'd like to revert to a standalone configuration. Unfortunately, I'm unable to find a "Remove" button in the web interface as suggested in the Proxmox documentation. I have followed the recommended steps, but the button is not visible.

Current Status:

this solution is for a user who has no node, no VM's. in my case the cluster attached to a node and this node contain VM's
