[PROBLEM] Moode 7.0.1 - MinimServer 2 on Synology

@Baltazarbugs

Have you ever watched a Road Runner cartoon where Wile E. Cayote runs off the edge of a cliff but doesn't know it until he looks down? That's me with this issue

The last lines in your final screen capture tell it all

Code:

df: /mnt/UPNP: Transport endpoint is not connected

but I was too focused on the MPD message for a specific track. Not just the path to the specific track but the path to the server itself is inaccessible. Obviously it was accessible when MPD scanned the tracks, otherwise the track wouldn't be in its database, but something happened afterwards. 

The UPnP Media Browser uses the FUSE file system to mount the remote server's offerings as if they were part of the local file system. Here's the first two levels of /mnt/UPNP on my moOde player after enabling the browser and creating a music source. Note that it found the Minimserver I asked moOde to scan but also another moOde player ("TR34b") on which the DLNA Server is enabled. In fact, it will find and mount all UPnP/DLNA Media Servers on the LAN.

Code:

pi@moode:/mnt/UPNP $ ls -l

I tried to repro your issue by simply turning off the Minimserver. The system fails gracefully. The /mnt/UPNP/[MinimServer[xenon] mountpoint disappears and if I try to play a track from MPD's database then an appropriate "Failed to decode...Failed to open...No such file or directory" error shows on-screen and the following entry appears in the MPD log

Code:

Mar 11 13:35 : exception: Failed to decode /var/lib/mpd/music/UPNPminim/75 items/Winter - Largo.dsf; Failed to open '/var/lib/mpd/music/UPNPminim/75 items/Winter - Largo.dsf': No such file or directory

Turn on the server and moOde/MPD can now play the same track.

I'm curious to know what you get with an "ls -l /mnt/UPNP" when you're having your issue.
