"ReadyNAS is unable to access the data volume. media backup"

Found the following thread / case 18587457 which seems to indicate it's a snapshot:
http://www.readynas.com/forum/viewtopic.php?t=63292

I did indeed manually create that snapshot.

So back to the original issue, I'm still receiving the green alert "The paths for the shares listed below could not be found. Typically, this occurs when the ReadyNAS is unable to access the data volume. media backup"-- and to correct my initial post, it still occurs even after stopping the sharing/streaming services and doing a reboot. This log item is coming from the RAIDiator service and showing up /var/log/syslog and /var/log/user.log
