Greetings. I have two server with proxmox vms on both. I want to make a cluster out of them. One of the servers has 10 virtual machines on it, other one is empty. I am concerned how would first server behave in thet scenario. Will my virtual machines be erased? Or they will remein intact?
 
Could you please explain why the node that joins has to be empty? What would happen if it wouldn't be empty? Thanks!
I specifically linked the wiki in my above post that explains what happens to a node that joins a cluster. Did you bother to read?

Anyway I'll give you the main pertinent quote;
All existing configuration in /etc/pve is overwritten when joining a cluster. In particular, a joining node cannot hold any guests, since guest IDs could otherwise conflict, and the node will inherit the cluster’s storage configuration.
