Expanding Storage in Proxmox: A Step-by-Step Guide

When you’re running a virtualized environment on Proxmox, eventually you’ll find yourself needing more storage. Whether it’s for new VMs, containers, or just data storage, expanding your available space is a critical task. This guide will walk you through the process of identifying your storage devices, preparing them for use, and adding them to Proxmox.

Identifying and Preparing Storage Devices

The first step in expanding your storage is to identify the storage devices attached to your Proxmox server. You can do this by running:

fdisk -l

This command lists all the disk devices available on your system. Once you’ve identified the disks you want to use for additional storage, the next step is to partition them. We’ll use cfdisk, a disk partitioning tool, for this purpose:

cfdisk /dev/sdb
cfdisk /dev/sdc
cfdisk /dev/sdd

With your disks partitioned, the next step is to create physical volumes (PVs) on these partitions. This is done using the pvcreate command:

pvcreate /dev/sdb1
pvcreate /dev/sdc1
pvcreate /dev/sdd1

Creating Volume Groups

After preparing the physical volumes, you’ll need to create volume groups (VGs). Volume groups are a pool of storage that can be allocated to virtual machines and containers. Create your volume groups with the vgcreate command:

vgcreate SSD1 /dev/sdb1
vgcreate SSD2 /dev/sdc1
vgcreate SSD3 /dev/sdd1

Adding Storage to Proxmox via the Web Interface

With the physical volumes and volume groups ready, the next step is to add this storage to Proxmox. This is done through the Proxmox web interface.
