LinuxMCE acts as a central file server for both SMB and NFS out of the box.
Any shares or connected disks that the system finds connected to the core, to the network, or any media directors, will be found, and if you allow LMCE to use them, it will add them to the system, one share for each, as well as making symlinks into audio, video, documents, pictures, and other (for public only shares).
We provide NFS and SMB shares for the disks, and if you use LMCE file structure, you can keep the media separate on the disks from other files, while still being able to access the disks individually if wanted.
