Hoping the /etc/exports file will still have all of your old export definitions.
If you're using an NFS adminhost you'll have to delete the current /etc/exports file before you copy the old one out of the snapshot directory.
Easier to copy it out of the .snapshot directory than to do a snaprestore.
You can do a volume snaprestore on vol0, which will initiate a reboot of the filer.
It would also revert you back to the expired NFS license. I wouldn't want to do that...
I hope this response has been helpful to you.
