ok before i get flamed with 800 questions here is my setup:
Dell Poweredge 1850 running Mint Linux and Plex Media Server
AMD Opteron 8 core with 16 GIG DDR3, 9 Sata HDD drives totalling 17TB with OpenMediaVault
1 Raspberry Pi B+
2 Raspberry Pi 2
1 Raspberry Pi 3
All devices connected through a 1 gig network, using Tyco AMP Cat6A cabling, a Dell 1 gig switch, a mini-ITX system running IPCop as firewall/router, and a cisco 1242AG wireless AP.
when I use the web interface i can see my entire library, but even with pre-caching each raspberry pi doesn't, and what they see are not the same on each device. is there something I could be missing in my configuration?
