Setting up NFS

Hi all

Trying to set up NFS because I'm getting lots of buffering to XBMC over SMB.
I've set up a new share and have enabled NFS but, whilst I can see the folder I cannot see anything other than the export/videos share. It will not let me browse within it.

Also tried from my Macbook to access the share but cannot.

Any ideas?

got it working in the end. had to edit the /etc/exports file to say the following instead of what OMV enters it as
not sure if it will keep this setting though

/media/MY_VOLUME xxx.xxx.xxx.xxx/255.255.255.0(rw,all_squash,insecure,no_subtree_check,async)

not sure which flag made it work. think it might be the all_squash one though.
