No, there is no way via GUI, only CLI as described here: https://pve.proxmox.com/wiki/Cluster_Manager#_remove_a_cluster_node
If you delete the folder of the node /etc/pve/nodes/pve1 it should disappear from GUI too.
Hi,
How should we recover from a lost node due to HW failure on a 3 nodes cluster ?
I can't see the VMs anymore, and have no direct way to restart them on remaining nodes.
Best guess is that I should remove the failing node from the cluster...
