I have a few Proxmox nodes in production which are all standalone nodes. Can I create a cluster of all then nodes without any shared storage and without affecting the VMs running on these nodes?
yes you can, but since you already have existing running vm setup already, when you adding the 2nd, 3rd nodes to the cluster, you must first make sure /etc/pve/qemu-server/ and /etc/pve/lxc/ has no config files (move all *.conf to /root/qemu-server and /etc/lxc/), then also make sure all your VM ID does not duplicated. for example, you can't have VM instance on NODE A with ID 101 running and also another VM instance ID 101 running on NODE B
