My PROXMOX cluster nodes:
As only two members are joined to cluster, following message will show you for any action you want to perform (Create VM, delete node, add another node, etc):
SSH to Master and change weigth (To have quorum :P )
BONUS: Remove a NODE from GUI, delete/move the whole directory /etc/pve/nodes/
GUI is clean, without "Quipu" :D

As only two members are joined to cluster, following message will show you for any action you want to perform (Create VM, delete node, add another node, etc):
root@ayllu:~# pvecm delnode quipu
cluster not ready - no quorum?
SSH to Master and change weigth (To have quorum :P )
root@ayllu:~# pvecm expected 1
Now remove node from Cluster and try to add another node into Cluster like this:
On Master:
root@ayllu:~# pvecm delnode quipu
On brand new Node:
root@apu:~# pvecm add 172.16.30.4
root@172.16.30.4's password:
