Before you begin:
  • Check if your hardware is supported on the system requirements page.
  • Download an installation image file for your system. openmediavault provides ISO installers for x86 architecture and several preconfigured images for ARM devices.
  • Disconnect all disk devices except the one for the system drive. This way you avoid an accidental install on a storage drive (which will be configured after installation anyway).
Installation variants:

Choose your installation variant and follow the instructions.

  • Dedicated drive - Advised method via ISO image. This runs OMV from its own drive.
  • USB flash drive - This runs openmediavault from a USB flash drive.
  • Debian Operating System - Use an existing Debian OS installation for openmediavault.
  • Debian Operating System via debootstrap. Use this as a last resort in case the installer does not recognize a specific essential hardware component like hard disk (NVME) or a network card that needs a higher kernel (backport).
  • SD card - This runs openmediavault from a SD card.
First time use:

If you have a screen attached, KVM or IMPI console the login screen will display the current IP address assigned for the web interface. Open your browser and type that IP address. The default web interface login credential is admin:openmediavault, the root password is the one you setup during installation.

For ARM images the root password is the same as admin password.


openmediavault will enable SSH access for the user root by default to be able to access a headless system in case of a broken installation or other maintenance situations. You should disable this behaviour in the Services | SSH page for security reasons after installation.

To still get root access you need to create a non-privileged user and add them to the ssh and sudo groups. After that you can SSH into the system with this non-privileged user and run sudo su.
