If your Synology NFS share stops working with Volumio after an update, follow these steps:
Check if the IP Address Changed: Verify whether your Volumio device has a new IP address. If so, update the NFS permissions on your Synology to match the new IP.
Update Permissions in Synology: In the Synology DSM UI, go to the shared folder settings. Under NFS Permissions, update the allowed IP address to the new one from Volumio.
Configure NFS Options in Volumio: Go to Sources → Add New Drive in the Volumio UI.
When entering mount options, use vers=3
Save the configuration
Rebuild the Music Library
Once mounted, Volumio will begin building the music database from your Synology drive.
