How can I delete a PROXMOX cluster?

I created a cluster on my proxmox node ("node01")

pvecm create cluster1

This is the output of pvecm status (i changed my ip address to 1.1.1.1 for security purposes)

root@node01:~# pvecm status

However i want to completely remove it. How can I do that?

PS: I'm using ubuntu server

Thanks!

I remember creating my Proxmox cluster using the GUI, and honestly ... I have never removed the cluster that I currently have working, but this information may be of use to you.
