- Initial Login: You will be prompted for the default username and password. The default credentials are typically "admin" and "openmediavault" (you can change this during the initial setup).
Step 3: Connecting Your DAS to the Raspberry Pi
- Connect the External Hard Drive: Once you've accessed the OpenMediaVault web interface, connect your external hard drive to the Raspberry Pi via USB or SATA (depending on your Raspberry Pi model).
- Format the Hard Drive (Optional): If you wish to use the entire hard drive for your NAS, you'll need to format it within OpenMediaVault. It's recommended to create a separate partition for the operating system and the storage space.
- Configure Shared Folders: Within the OpenMediaVault web interface, navigate to "Shares" and create new shared folders. Specify the location of the shared folders on your external hard drive.
- Set Permissions: Define the access permissions for each shared folder. You can restrict access to specific users or groups.
Step 4: Configuring Network Settings
- Network Settings: Within OpenMediaVault, navigate to "Network" and configure your network settings. Ensure that your NAS is accessible on your local network.
- Static IP Address (Optional): For a more stable connection, it's advisable to assign a static IP address to your Raspberry Pi.
Step 5: Accessing Your NAS from Other Devices
- Access from Windows: On Windows computers, you can access your NAS by mapping a network drive. You can use the IP address of the Raspberry Pi or a hostname (if assigned).
- Access from macOS: Similar to Windows, you can map a network drive on macOS to access your NAS.
- Access from Linux: On Linux systems, you can access your NAS using the
mountcommand. - Access from Mobile Devices: Numerous NAS apps are available for Android and iOS devices, allowing you to access your NAS from your smartphone or tablet.
Security Considerations: Protecting Your NAS
Security is paramount when creating a NAS. Consider these precautions:
- Strong Passwords: Use strong passwords for your OpenMediaVault user accounts and for any other services you install on your NAS. Avoid common or easily guessed passwords.
- Two-Factor Authentication (2FA): Implement two-factor authentication for your OpenMediaVault user accounts, adding an extra layer of security.
- Regular Updates: Keep your OpenMediaVault operating system and all installed plugins up-to-date. Updates often contain security patches.
- Firewall: Enable the built-in firewall in OpenMediaVault and configure it to block unauthorized access.
