I recently bought a Synology NAS and decided to use it as database for my OpenELEC machine.

I made the following NFS share on my NAS:
path: /volume1/xbmc
IP: 192.168.1.36
Privilege: read/write
Root squash: No Mapping
Asynchronous: Yes
Non-priviliged port: Yes
Security: sys

I created an advancedsettings.xml with the following mapping for thumbnails:
<pathsubstitution>
<substitute>
<from>special://masterprofile/Thumbnails/</from>
<to>nfs://192.168.1.58/volume1/xbmc/Thumbnails/</to>
</substitute>
</pathsubstitution>

I can see some single letter/number directories appearing on my NAS, with images in it, so XBMC seems to have no issues with writing to the NFS share.

However, in XBMC I hardly see any thumbnails at all, only a few movies seem to have them.

The movie Argo has a Thumbnail, but Total Recall is missing the thumbnail.
I posted part of the logfile on pastebin

Can anyone help me get thumbnails for all movies/tv shows?

I noticed that only thumbnails were missing for movies/tv shows I had prior to making a shared database on my NAS.

Also, my fresh Windows installation of XBMC was showing all thumbnails (on my NAS)

I fixed the problem in OpenELEC by deleting the userdata\Database folder.
