How to update IP addressing on a Proxmox Cluster

When you change something in your network configuration, rather than its the gateway or the IP addressing, you may come under serious troubleshooting on your Proxmox Cluster, so this document will guide you into the necessary steps needed to update your network settings on Proxmox.

Note : You must follow these steps on every single node of your cluster to let it able to handle the synchronization between each node once.

So firstly, you will need to change the network interface configuration of the system; it is preferable for you to set a static IP:

Arch Linux Full-Disk Encryption Installation Guide [Encrypted Boot, UEFI, NVMe, Evil Maid]

Arch Linux Full-Disk Encryption Installation Guide

This guide provides instructions for an Arch Linux installation featuring full-disk encryption via LVM on LUKS and an encrypted boot partition (GRUB) for UEFI systems.

Following the main installation are further instructions to harden against Evil Maid attacks via UEFI Secure Boot custom key enrollment and self-signed kernel and bootloader.

Preface

You will find most of this information pulled from the Arch Wiki and other resources linked thereof.

Note: The system was installed on an NVMe SSD, substitute /dev/nvme0nX with /dev/sdX or your device as needed.
