To save people some time - I had NFS working just fine under 5.1 with a drive shared out under FreeNAS, but I wanted to use a USB drive connected to one of my DD-WRT based routers so this necessitated SMB/CIFS. Through much trial and error this is what worked for me:
- add the relevant info under the NAS tab. case is not relevant.
- use a "/" in front of the share name (important - will now work without it)
- HDD shows "Offline" under Storage Management tab
- reboot the cam
- HDD shows "Online"
- format
