There are few things that you need to do prior to sharing an NFS volume:
1. Create a Filesystem from the HDs you have
2. Create a Volume on the Filesystem
3. create an NFS share in the NFS menu. ( in the NFS Menu -> Shared Volume. click add NFS share)
4. enable NFS service
than the NFS mount will be availale via:
EasyNAS Server IP/ share name
I hope this helps
