It does not look like similar functionality exists (documented) for cDOT. For CIFS you can control visibility on share level, but for NFS it is all or nothing.

Hi and thanks for answering.
We have tried the volume setting. The problem with that is that it makes the snapshots completely inaccessible to the NFSv3 client. If the snapshots are inaccessible then you cannot access snapshot backup copies from the client, and we want to do that.
I want the snapshots to be accessible but not visible, as we have in 7-mode.
Thanks, Jeremy

In 7-mode you could hide the snap dir on each volume by changing the option nosnapdir to on
In C-mode the just do a vol modify <vol_name> -snapdir-access false to hide the snapshot from the system that has access to it

In this mode there is a .snapshot directory, but if you ‘ls’ that directory it appears empty. However, if you ls .snapshot/hourly.0 say then you can see that the snapshot is in fact there.
We now have an 8.3.1 CDOT filer and have not been able to work out how to reproduce the behaviour. The snapshots are either accessible and visible (which causes problems for programs which walk the tree) or not accessible at all.
NetApp support have not been able to help so far. Can anybody on this list?
Thanks, Jeremy
p.s. the relevant 7-mode option is:
nfs.hide_snapshot on
