Raspberry Pi NAS: Install OpenMediaVault + CasaOS (Step-by-Step Guide)

Is OMV + CasaOS the Ultimate Home Cloud Setup?

In today’s era of data privacy concerns, rising cloud costs, and digital ­sovereignty, many tech enthusiasts and home users are turning to self-hosted solutions. One promising combination we are installing OpenMediaVault (OMV) with CasaOS On Raspberry Pi5. In this piece, we’ll explore how to setup, what tradeoffs exist, and whether it can truly serve as a “Easy home cloud solution.”

Step-by-Step Guide - Install OpenMediaVault + CasaOS

Step 1 - Install Raspberry Pi OS Lite (64-bit) in your memory card, Create root login and pass too.

Step 2 - Start Your Raspberry Pi

Step 3 - Install OpenMediaVault

wget -O - https://raw.githubusercontent.com/OpenMediaVault-Plugin-Developers/installScript/master/install | sudo bash

Setup 4 - Change Your OpenMediaVault Port - 80 to 8080

Login to your Raspberry pi using terminal.

sudo omv-firstaid

OpenMediaVault - First Aid will appear after above command. Select the Option 3 - Configure Workbench

Change the http port to your choice - in above picture, i changed the port to 8080.

Default Username and Password of OpenMediaVault :

ID : admin

Password: openmediavault

Step 5 - Install CasaOS with 1 command.

   sudo apt update && sudo apt upgrade -y
   sudo apt install curl -y
   curl -fsSL https://get.casaos.io | sudo bash

Step 6 - Login to your Local IP url ( eg - 192.68.1.55 ) of Raspberry pi and create CasaOS Home Cloud Account.

The Reason Behind Combining Them

The appeal of combining OMV + CasaOS is that you can get the best of both worlds:

• Use OMV as a robust foundation: manage storage, disks, RAID, plugins, file services.

• Layer CasaOS on top (or alongside) as a friendly interface for running apps, dashboards, and “cloud-like” experiences for non-technical users.

Thus, rather than choosing one or the other, this hybrid approach can target both stability and ease-of-use.

Pros & Cons: What to Expect

Advantages

• Flexibility — you can use OMV’s mature features while presenting a friendly interface via CasaOS.

• Reduced learning curve — CasaOS can make app deployment simpler for non-expert users.

• Self-sovereignty — all data stays under your control, no third-party cloud needed.

• Cost savings — once hardware is in place, ongoing costs are mainly power and maintenance.

Challenges & Tradeoffs

• Missing features — CasaOS lacks essential features like built-in RAID. You must lean on OMV (or other tools) for redundancy.

• Complex setup — combining two systems can introduce integration challenges, version conflicts, or maintenance overhead.

• Performance considerations — depending on your hardware, running both systems may tax resources.

• Support & stability — CasaOS is newer and may have edge-case bugs, while OMV is more battle-tested.

Use Cases & Recommendations

This setup is particularly suited for:

• Home users who want to self-host media servers, file storage, web apps, and dashboards.

• Tech enthusiasts who want both control and a nicer interface.

• Small offices or labs where budget and data privacy matter.

However, if your primary need is resilient, enterprise-grade storage, or if you’re uncomfortable troubleshooting OS issues, you might prefer a more integrated solution (e.g. TrueNAS, Synology, etc.). But TrueNAS is only work on X86 processor not on Arm.
