Unfortunately I am not 100% sure what exact model our NAS is, however it is a ReadyNAS 4 bays running 4 2tb drives (it cant run anything larger than this).

Sounds like the original NV+ (called a v1 here).  Does it say "ReadyNAS NV+" on the front panel? Note if it says "ReadyNAS NV+ v2" it's a different platform (and could accomodate larger disks).

The admin portal should also confirm this - you should see the NAS model in the upper right of most of the screens.  The home screen should also have a model field, and also would have the firmware version (should be 4.1.x for an NV+ v1).  It'd be useful to know the firmware version.

It would also be useful to know if your admin password changed back to the default when it switched back to X-RAID. (The default for the NV+ is netgear1.)

I then logged into the admin portal and saw Disk 1 showing Offline.

Then I restarted the NAS box (software restart in the admin portal)

After restarting, all drives are Online and ReSync occurred.

Now the NAS is showing X-Raid and we are unable to see any of the data.

 

The Admin portal still shows 5.44tb of data is there, however we cannot access it.

Any ideas on what we could do to change this back to Raid5 without losing data?

FWIW, X-RAID is a application layer on top of standard RAID which makes RAID expansion easier to manage - it is actually still running RAID-5.

Do I need to get any more specific information? If so, I am new to this so please help with instructions 🙂

Can you please download the full log zip file from the admin portal?

Select "status" from the left pane, and the "logs".  "Download all logs" is on the upper right. Though the screenshot below is from a different model, the log screen should be the same as what you have.

The system will then create a zip file (which can take a minute or so), and then should download it to your PC/Mac.

You can put this into cloud storage (dropbox, google drive, etc) and share the link, so others can take a look.  Don't post the link to the zip file publicly - send it in a private message (PM).  There is some privacy leakage.  You can send a PM using the envelope icon in the upper right of the forum page.

I'd be happy to take look (though note I don't work for Netgear).  If you'd prefer that a Netgear mod review the logs, you can reach out to either Marc_V or JeraldM.
