new setup across vlans/subnets

[simbun]

I'm not going to be able to answer the Volumio questions yet as I use it purely as a UPnP renderer, but I should be able to have a play tomorrow. I'm sure that Volumio will store any playlists within it's own config and not the music folders but I'll have a look tomorrow.
It sounds like your NFS troubles are with the NAS as well as Volumio, have you got it mounted on any other system?

MinimServer just needs read access to your music and it won't be causing any contention, unless for some reason Volumio needs to lock a file but I'm pretty sure that won't be the case.

If you're already using foobar just right click on one of the playlists and 'Save Playlist'. As long as you save it within the music directory or directly above it, it will use relative paths.
