Build a NAS system with OpenMediaVault and a Raspberry Pi

Users and Groups

The next task is creating more users in OpenMediaVault by means of the Access Rights Management | Users dialog, which is accomplished by clicking on Add and defining your settings in the dialog box. After you have saved and applied the configuration, you can go on to create your own home directories for the newly-created users in the Settings tab. If you later wish to change the settings you defined, click Edit at the top above the application window's list view.

Users on OpenMediaVault belong to different groups. There are numerous out-of-the-box groups available on the system; you must select one or more of these groups when defining new users. If the existing group structure does not meet your needs and you want to add new groups to the system, use the Access Rights Management | Group dialog box.

Sharing

The final step is to define sharing and enable some services so that users working from desktop computers can access existing drives and directories in OpenMediaVault. Open the Shared Folders entry from the Access Rights Management menu and create a new shared folder by clicking on Add in the Shared Folders tab.

The configuration dialog allows you to specify a name and path. You can also assign permissions (for which the system clearly explains the various options). The button panel offers several other options for customizing the shared folder.

The most important of these options is the ACL button. A detailed dialog accessed lets you define specific access control lists (ACLs) for every single share, allowing fine-tuned allocation of rights (Figure 3).

Figure 3: You can assign very detailed permissions with ACLs.

After completing all the settings for sharing drives and folders, you can finish by setting up the desired background services (daemons) on Services. OpenMediaVault will only unlock access via SSH by default, so if you use the OpenMediaVault Rasp Pi in a heterogeneous network, you must enable Windows workstations access to the Rasp Pi through SMB/CIFS. A more complex dialog allows extremely detailed settings for SMB access.

You have the option of enabling other services, such as the ClamAV virus scanner. However, you must first install ClamAV via System | Plugins. The Anti-Virus entry will then appear in the left sidebar, which also branches out into a detailed settings dialog. OpenMediaVault allows actions from this box, including detailed scanning of various content and file types for malware.
