Unable to delete Node from Cluster

[malgates]

Hi everyone,

I added a 2nd node called pve2 to my cluster. Unfortunately I did a configuration error and I had to remove the 2nd node again. I followed the guide: https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node

I was able to remove the node, but it is still there in the GUI.

When I am clicking on it I am getting the follwoing error:
hostname lookup 'pve2' failed - failed to get address info for: pve2: No address associated with hostname (500)

When I go to data center I am getting the follwoing error:
'/etc/pve/nodes/pve2/pve-ssl.pem' does not exist! (500)

Any ideas? THX

So "clusterkill.sh pve2" would do for you (if further problems reboot your 2 nodes after script usage) :
cat clusterkill.sh
#! /bin/bash
