Remove a cluster node

[johnplv]

Explain please. In wiki (https://pve.proxmox.com/wiki/Proxmox_VE_2.0_Cluster) says:

If for whatever reason you would like to make that server to join again the same cluster, you have to

• reinstall pve on it from scratch
• as a new node

What does that mean exactly? New name, new ip address, or both?
For example, if I remove the "node1" with ip 192.168.0.1, reinstall pve, I must:
1) change the name such as "node1a", but can leave same ip 192.168.0.1
2) change the name and ip address as "node1a" and ip 192.168.0.11

PS: Can i rejoin node with same name and ip with option "--force"? What problems it may cause

With the name and IP address that you want

Can i rejoin node with same name and ip with option "--force"? What problems it may cause

It is -force , with only a symbol

Yes, the target is that a PVE node can rejoin to a cluster PVE
