no music found on nfs share

hi.
i do have a synology nas with my music library.
also i have a new raspberry pi on which i installed subsonic.
via the admin page i told subsonic to scan my media files:
NAME: A
FOLDER: /media/subsonic/A
this folder points to a nfs share on my nas:
mount -t nfs -o soft 192.168.178.30:/volume1/Musik/A/ /media/subsonic/A/
i do have the same user on my nas and on my pi. also this user is allowed to read-only my music library.
when scanning my media files in subsonic it scans the folder but finds no media...
what could be the problem here?
can i give more input?
thanks a lot
