Hi.
i'm new menber, and sorry for my english...

I would like to create a cluster with three nodes.
In the master node I activated the cluster when I was still in the laboratory and I used an ip 192.168.1xxx.
Now the server is in production and the network has another subnet, 192.168.10.xxx.

The previous IP (192.168.1.xxx) remained in the Cluster Join information, the other two nodes, which are configured with the LAN 192.168.10.xxx, are unable to join.

How can I change the ip and make sure that the right ip is obtained in the information for the join?
Can I start over?

Ok.
but in /etc/pve/corosync.conf, there isn't 192.168.1.178, that is the ip in Cluster Join Information.
There is only vmbr2 123.123.123.1, this is valid ip.
I have to change the other IP, 192.168.1.178.

this is a cat of corosync.conf

Oh, sorry that's actually the main IP address of the node, so you'd have to check the /etc/hosts config, which can also be managed through the web-interface.

Check there for the entry mapping your node-name to the "old" IP and switch it over to the new one.
