No available interfaces for cluster creation

[ltcptgeneral]

From the documentation, it seems to suggest that using a separate network interface for the cluster is optional, but when I try to create a cluster, there are no available interfaces to use. The current deployment only has one interface which is slaved by the linux bridge. I can add another NIC in the future, but I would prefer to test the feature without having to add a bunch of NICs to each node. Is there anyway to use the existing interface to test this feature?

What I am expecting (from the docs):


What I am getting:

Hi,
what is the output of pvesh get nodes/localhost/network --output-format json-pretty and cat /etc/network/interfaces? Feel free to censor any public IPs, but in such a way that it's still possible to tell if two are the same.

Well, there's no IP address assigned to the bridge. It should match the one configured in /etc/hosts.

 

[ltcptgeneral]

That seems to have solved the issue. However, I prefer that nodes use dhcp without static mapping. I have a dns server which can resolve local lookups. Would it be possible to continue using dhcp for nodes when the cluster seems to expect static mappings?

Proxmox VE nodes are expected to be configured with a static IP AFAIK.
