Connecting one Rasp. to another Raspb. USB drive (solved)

[masterguido]

Hi, first thanks for your excellent work!
I am the proud owner of a raspberry pi 2 with Runeaudio for more than 2 years, and I recently bought a RPi 3.
My intention is to connect the new RPi3 to another amp, but using the 3TB flac music collection already connected to the RPi2 via an USB external powered drive.
I have tried to connect it as a Network share, with the RPi2 ip, and the remote directory dev/sda1 (the point at which is connected the USB drive) but with no luck.
Also tried USB/MUSIC but no connection at all.
Any ideas?

Thank you very much Frank!
In my Pi the share was music_store, but I only change that and it works perfectly.
Thanks again
