Autodiscover on mounted network music folder not working

@support @danny

I have Roon core running on a NUC with Debian (8) and music stored on a NAS. Roon mounts the music share fine and playback is stable, but I have to ‘Force rescan’ every time I add albums. There is no automagic

df -i give this output:
root@nuc:~# df -i /mnt/RoonStorage_26c9306a0fbd9d9d62b5678af411ff87cae5bd9f/Music/
Filesystem Inodes IUsed IFree IUse% Mounted on
\xxx.xxx\media 0 0 0 - /mnt/RoonStorage_26c9306a0fbd9d9d62b5678af411ff87cae5bd9f

So the cifs mount does not include inode messaging. Is this the reason? The linux based distro on the NAS (readynas Ultra 2) is fairly old, but df -i on the NAS shows normal inode count.
