When setting up a Proxmox VE environment it is common to end up with a node named pve , which is the default hostname assigned during installation. This becomes a problem when managing multiple Proxmox servers since every node will show up as pve in the web UI. This post covers the complete process for renaming a Proxmox node to a meaningful name including the FQDN, and how to handle the pmxcfs filesystem quirks that make this more involved than a standard Linux hostname change. Understanding How Proxmox Uses the Hostname Proxmox VE derives the node name directly from the short hostname (the part before the first dot). This means a server configured with the FQDN pve-node-1.example.lan will appear in the UI as pve-node-1 . It is important to plan the naming convention carefully upfront. A naming scheme like pve-node-1 , pve-node-2 works well because the short hostname is already fully unique, without relying on the domain portion to differentiate nodes. Proxmox stores its ...
