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

Hi all,

today I create some kind of a mess.

TL;DR
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 
failure".
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?


Thanks,

	Uwe
