Removing a Node

Follow these steps to remove a node from the cluster:

Delete or migrate any VMs that are running on the node that you want to remove. This step ensures that no active VMs are impacted during the removal process.
SSH into a working/running node in the Proxmox cluster.
```
ssh username@IPAddress/Hostname
```
Check which nodes are online in the Proxmox cluster. Run the following command:
```
pvecm nodes
```
Identify the name of the offline node that you want to remove.
Delete the offline node using the following command:
```
pvecm delnodes <nodename>
```
After executing the above command, refresh the Proxmox GUI to ensure that the node is fully removed from the cluster.
