Hi,

I’m experiencing a reproducible issue and I’m trying to determine whether this is a configuration problem on my side or a potential bug.

Setup

• Local Unraid server

• WireGuard tunnel configured via Unraid VPN Manager

• Remote Unraid server

• SMB share mounted from the remote server using the Unassigned Devices plugin

• The remote share is accessed over the WireGuard tunnel

• I use borgmatic to send daily backups to this SMB share

What happens

1. I connect to the remote Unraid via WireGuard.

2. I mount the remote SMB share using Unassigned Devices.

3. Borgmatic runs daily backups to that mounted share.

4. If the WireGuard tunnel drops (or is disconnected) while the SMB share is mounted, the local Unraid WebGUI becomes completely unresponsive.

At that point:

• The WebGUI hangs.

• The system appears stuck.

• SSH may still respond.

• If I manually run:

wg-quick up wg0

the WireGuard tunnel comes back up and the WebGUI immediately becomes responsive again.

Observations

• The issue only occurs if the SMB share is mounted.

• It appears the system blocks while waiting on the unreachable network mount.

• As soon as the tunnel is restored, everything resumes instantly.

• There doesn’t seem to be graceful handling of the broken network mount.

• I discovered this specifically because borgmatic uses this mounted SMB share as a backup repository.

Questions

• Is this expected behavior when a network mount disappears while in use?

• Should a dead SMB mount be able to block the entire WebGUI?

• Are there recommended mount options (soft mount, timeouts, etc.) to prevent this?

• Is this something specific to Unassigned Devices?

• Is mounting a backup target over WireGuard in this way considered bad practice on Unraid?

My expectation would be that losing a VPN connection should not cause the entire WebGUI to become unresponsive.

I’d appreciate any clarification on whether this is normal Linux network mount behavior or something specific to Unraid.

Thanks.

You could test with Tailscale instead; it may better handle the dropped connection.
