[SOLVED] Cluster Node with wrong IP

[gtrovato]

Hi All,

I'm not able to create a cluster with Proxmox 6.2-12.
I've the first node running:

root@pve-AI-1:~# pvecm status
Cluster information
-------------------
Name: test01

Nodeid Votes Name
0x00000001 1 172.16.1.231 (local)

When a try to add a node to it, I have:

root@pve-AI-1:~# pvecm add 172.16.1.223
Please enter superuser (root) password for '172.16.1.223': ***********
detected the following error(s):
* local node address: cannot use IP '172.16.1.231', not found on local node!

Check if node may join a cluster failed!

The node ID is wrong, since the IP of the first node is 172.16.1.223, and I'm not able to find where the IP 172.16.1.231 comes from!
I've the same issue using the WEB UI.

Thank you!

hi,

what are the contents of /etc/hosts on both machines?

Solved!

The problem was the host name.
It's a testing environment nested on Proxmox; I've cloned the VMs, so they had the same name!

Thank you very much Oguz!

hi,

I ran into the same issue. I changed the /etc/hosts file on all of the machines but one. Made the change and now it has joined the cluster.

Thanks oguz!
