To change the default storage for Ludus to your new NFS share, you need to perform two main steps: first, grant the necessary permissions in Proxmox, and second, update the Ludus configuration file.

### ⚙️ Step 1: Grant Permissions in Proxmox

Ludus users need to be able to access the new storage pool. You can set this up via the Proxmox command line.

1.  Log in as `root` to your Proxmox host (or the node where the NFS storage is mounted).
2.  Run the following commands, replacing `<your new storage>` with the **exact Storage ID** you created in Proxmox (e.g., `omv-nfs`):

    ```bash
    pveum acl modify /storage/<your new storage> -group ludus_users -role DatastoreUser
    pveum acl modify /storage/<your new storage> -group ludus_admins -role PVEDatastoreAdmin
    ```

    > **Note:** The `DatastoreUser` role is generally sufficient for using the storage, while `PVEDatastoreAdmin` grants more extensive management permissions.

### 📝 Step 2: Update the Ludus Configuration File

Now, you need to tell Ludus to use this new storage pool by default.

1.  Open the Ludus configuration file in a text editor (like `nano` or `vim`):
    ```bash
    sudo nano /opt/ludus/config.yml
    ```

2.  Find and modify the following parameters:
    *   **`proxmox_vm_storage_pool`**: Set this to the **Storage ID** of your NFS share (e.g., `omv-nfs`).
    *   **`proxmox_vm_storage_format`**: Set this to `qcow2`. This is the recommended and most compatible disk format for directory-based storage types like NFS.
    *   **`proxmox_iso_storage_pool`**: You can also set this to your new storage pool if you want to store ISO images there. Otherwise, leave it as `local`.

    Your configuration should look similar to this:

    ```yaml
    proxmox_vm_storage_pool: omv-nfs
    proxmox_vm_storage_format: qcow2
    proxmox_iso_storage_pool: omv-nfs # Or keep as 'local' if preferred
    ```

3.  Save the file and exit the editor.

### 🔄 Step 3: Restart Ludus Services

For the changes to take effect, you must restart the Ludus services:

```bash
sudo systemctl restart ludus ludus-admin
```

After completing these steps, any new VMs or templates created by Ludus will automatically be stored on your NFS share.
