Proxmox Cluster IP 0.0.0.1

[myOmikron]

Hi,
I'm having trouble, while setting up an Proxmox Cluster. When creating the cluster, I have set the link0 address to my internal network in which only the hosts are connected, but when I'm displaying the Join information, it shows 0.0.0.1 as IP Address.

When I'm trying to join another node, I'm getting the error message:
detected the following error(s):
* local node address: cannot use IP '0.0.0.3', not found on local node!

Network config of the first node:

source /etc/network/interfaces.d/*

auto lo
iface lo inet loopback

iface lo inet6 loopback

auto enp6s0

What do you have in the /etc/pve/corosync.conf file?

 

[myOmikron]

logging {
  debug: off
  to_syslog: yes
}

nodelist {
  node {
    name: 01
    nodeid: 1
    quorum_votes: 1
    ring0_addr: 10.255.255.1
  }
}

quorum {
  provider: corosync_votequorum
}

totem {
  cluster_name: Cluster
  config_version: 2
  interface {
    linknumber: 0
  }
  ip_version: ipv4
  link_mode: passive
  secauth: on
  version: 2
}

After reinstalling the server, I noticed, that in the summary tab of the Datacenter the node is the wrong IP Address, too. I haven't created the Cluster yet

Once thing I noticed is that you showed the contents of /etc/network/interfaces.d/*.

Do you not use the /etc/network/interfaces file directly? I haven't checked in the code but since the network config in the GUI uses the interfaces file and not files in the interfaces.d directory, it might be possible that this is where the weird behavior comes from.

The directoy /etc/network/interfaces.d/* is empty, but I think I have resolved the issue by setting another hostname. My original hostname was 01.proxmox.***.***, so I think proxmox interpreted this somehow as IP Address. After changing, the correct IP appears in the dashboard and the cluster creation fails no longer.
