Installing OpenMediaVault to a Raspberry Pi?

OpenMediaVault (OMV) is an open-source network-attached storage (NAS) solution based on Debian Linux. It provides an intuitive web-based interface for managing storage media and user access privileges. Installing OMV on a Raspberry Pi allows you to convert the tiny single-board computer into a fully-featured NAS device.

Installing OpenMediaVault to a Raspberry Pi?


Before installing OMV on your Raspberry Pi, you’ll need:

  • A Raspberry Pi model with built-in Ethernet and USB ports. Models 2B, 3B, 3B+, 4B are recommended.
  • A MicroSD card with at least 16GB capacity.
  • A power supply for the Pi.
  • Ethernet cable to connect the Pi to your local network.
  • At least one external USB hard drive or flash drive for storage.

Installation Steps

Follow these step-by-step instructions to get OMV running on your Raspberry Pi.

1. Download the OMV Image

First, download the latest OMV install image from the official website. Choose the Raspberry Pi image.

2. Flash the OMV Image

Use balenaEtcher or Rufus to flash the OMV image onto your MicroSD card. Be sure to select the correct target device to avoid accidentally overwriting your hard drive.

3. Connect Drives and Boot the Pi

Insert the MicroSD card and connect your USB storage drives to the Pi. Also connect it to your local network via Ethernet. Finally, apply power to boot the Pi.

4. Complete the Web Configuration

From another system on the same network, access the OMV web interface at http://openmediavault.local or the Pi’s IP address. Accept the disclaimer and complete the initial configuration as prompted.

5. Add USB Storage Drives

In the web UI, click on Storage to manage physical disks. Select your connected USB drives to mount and format them for shared storage.

6. Create User Accounts and Share Folders

Navigate to Access Rights Management and Shared Folders to create user accounts and shared folders for your NAS. Set the desired access permissions.

Performance Tweaks

Apply these tweaks to improve transfer speeds and overall performance.


  • Use a Gigabit Ethernet adapter if your Pi model supports it
  • Enable jumbo frame support in OMV network settings
  • Set MTU size to 9000 if your network equipment also supports jumbo frames


  • Use external SSDs or RAID arrays for best performance
  • Format disks using XFS or EXT4 file systems


  • Disable unnecessary services like DLNA to conserve resources
  • Limit the max number of torrent download slots (if using the built-in Transmission client)

Scheduled Scripts

Create custom scripts to run tasks like SMART disk checks and firmware updates on a schedule.

Why Choose OMV for Raspberry Pi?

Here are some of the key advantages of using OpenMediaVault for network attached storage rather than a desktop OS:

  • Specifically designed for NAS tasks like storage, backup, sharing, user management and more
  • Lightweight OS has less overhead than a desktop environment
  • Designed to run 24/7 without lagging or crashing over time
  • Active development and community support
  • Intuitive browser-based dashboard for easy remote management
  • Expandable storage and functionality via plugins

So if you need a cost effective, flexible, and user friendly NAS, installing OMV on a spare Raspberry Pi is hard to beat!

Frequently Asked Questions

  1. What are the minimum Raspberry Pi requirements for running OMV?
    The minimum is a Raspberry Pi 2 or 3, with built-in Ethernet connectivity. 1GB RAM is also recommended for best performance.

  2. Can I boot OMV from a USB drive instead of the SD card?
    Yes, you can run OMV from a USB flash drive or hard disk connected to the Pi. This may yield better disk performance.

  3. Do I need a Linux background to manage OpenMediaVault?
    No, the web-based dashboard is very user-friendly. No Linux expertise is required for basic operation.

  4. Can I access the Pi’s terminal with OMV installed?
    Yes, you can access the terminal over SSH to run Linux commands for advanced management.

  5. Is software RAID supported to combine multiple USB disks?
    Yes, OMV supports popular RAID levels like 0, 1, 5, 10 for performance and redundancy.

  6. Can I automate backups from client PCs to the OMV NAS?
    Yes, OMV has a built-in backup service that supports rsync jobs for UNIX and Windows clients.

  7. How do I migrate an existing OMV install to new hardware?
    You can simply image your existing SD card or OS drive to the new Pi or PC. Some configuration tweaks may be needed.

  8. What RAID configurations does OMV support?
    OMV supports JBOD, RAID 0, 1, 5, 6, 10 with support for hot swapping drives in some modes.

  9. Can I run other server apps like LAMP stack alongside OMV on the Pi?
    Yes, additional Debian packages can be installed via SSH to transform your OMV NAS into a multipurpose server.

  10. Which filesystems does OMV allow for external drives?
    EXT4 and XFS are recommended for the best performance. Other Linux filesystems like EXT2, EXT3, BTRFS are also supported.

  11. Can I schedule scrubbing on RAID arrays?
    Yes, you can schedule monthly or weekly data scrubbing on your RAID arrays via cronjobs to check for bad sectors.

  12. Does OMV integrate with cloud backup services?
    Yes. Plugins are available for direct cloud backup to Dropbox, Google Drive, Amazon S3, Backblaze B2 amongst others.
