There are a couple of different causes for this problem, but the most common is that two disks have failed (which destroy the volume). Another is that there was an unexpected power failure (or maybe a crash) which resulted in an out-of-sync volume that couldn't be mounted.
Are you seeing disk or volume errors on the logs page of the Web UI?
From there you can also download the full log zip file, and look in disk_smart.log That will tell you how what (and how many) disks are working in your system. You might also look in system.log and kernel.log for disk or volume related errors.
As far as solving it goes, if you have a backup then the simplest thing is to do a factory default, set up the NAS again and restore the data.
The other option is to contact Netgear paid support. Though there unfortunately is a good chance that resolving this would require their data recovery service. https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service

Does the NAS show the correct volume usage on the home page of Frontview and under Volumes?
If so, another possibility is that this could simply be a messed up Shares.conf in the samba config and the data may all stll be there.
The shares being listed in the list of users is a carry-over from the legacy Share security mode that was discontinued several years ago. Frontview looks at the samba Shares.conf and if the system is not in Share security mode it realises that the shares are not users and filters those out. However if shares.conf is corrupt or blank it won't realise that the shares are not users.
