Hi Uwe. 

All documetation that I know say changing the hostname and IP is not possible after cluster creation. 

Once I tried fix this issue and the solution was remove the node, reinstall and add the node on the cluster.

Assunto: [PVE-User] Renamed node, now WebUI partly not working 

Hi all, 

today I create some kind of a mess. 

I added one node with the wrong hostname to an existing cluster, tried to rename the node, now some parts of the WebUI 
don't work anymore. Any thoughts? 

I have a 3 node cluster with up-to-date software and added a fourth and fifth node. By accident, the fourth node had a 
wrong hostname. I tried to rename it by following [1] but forgot to increment totem {config_version}. 

Now on the WebUI -> Server View -> Datacenter -> <node> -> Summary page, the inlined status panel shows "communication 
If I try to migrate a VM to another node the drop down list for target node selection is empty (also when trying to do 
bulk migration). 

Any idea what I did wrong and how to repair the cluster?
