Itunes on wd usb drive not working

hi,

i got a wd my-cloud-4tb (v04.01.00-408) and connected a wd 2tb usb hdd.

on the usb drive is my itunes music.

i have activated dlna & itunes server in dashboard settings.

dlna works on my devices (iphone,ipad,philips tv).

on mac 10.10 i have installed the latest itunes (12.0.1.26)

itunes find the wd-my-cloud but could not display anything.

itunes show after 1minute the local music again.

so something goes wrong.

how can i check if itunes-server running correctly on my-cloud ?

are there any log files or where can i find the library files via ssh for the itunes-server ?

thx

I may be wrong, but I’m pretty sure that iTunes Server ONLY uses the 

/Public/Shared Music

folder on the internal drive – not any USB devices.

no.

if i “rebuild” the itunes database in the dashboard i can connect with itunes on my macbook to the my-cloud-itunes-server.

i can see tracks and albums but i cant see any covers (covers are integrated in the files by “tune instructor”.

but sometime later i cant connect to wd and be redirected to local.

i think something goes wrong with the rebuild.

therefore i want to know if there are any log fles where i can see the reason.

i have moved all mp3 to public/shared music directory.

after 2 days of transfer and file scanning inside the mycloud,

same problem like on usb-hdd. (the usb hdd is not connected to my cloud.)

itunes try to connect and after while itunes switch back to local library.

something goes wrong but i dont know what to do.

anybody know what to do or where i can search for solutions ?
