This question had been asked before but in a different way.
I have an RPi2 and it works fine but I want to set it up as a NAS. I think I got the NAS part setup since I can ftp to it and Samba is already setup on it, but I just want to know how to get other Pi’s I will have will access the NAS. I’m going to build 2 more Pi’s and I want to make sure they can all access the media files.
