Are you running Windows 10?  If not, what are you running?

What firmware is running on the NAS?

meant to say that i CAN'T access from my adroid devices.

here are the details. front screen on the NAS reads the correct disk usage but web screen shows 0% usage. but the DLNA server is still serving all my media files. 

Model: ReadyNAS NV+ [X-RAID]

Serial: 23J3017U0046A Firmware:

RAIDiator 4.1.15 [1.00a043] 

Memory: 256 MB [2.5-3-3-7]

IPv4 address:: 192.168.0.100

Ok.  So SMB/CIFS has stopped working and Frontview is thinking you have 8 MB disks with a 0 MB volume.  DLNA still functions.

 

Something looks very wrong. 

  • Can you download the log zip file?  (Don't post it here, but it'd be good to have it).
  • Is SSH enabled on the NAS?
  • Do you have a backup of the files?

when i tried to reinstall the os from usb i get the "os index error" and it hangs there 

when i try to do anything from the web front end that requires a reboot it wont reboot itself.

There's a download option on the logs page in frontview.

 


@starbase804 wrote:

Then it's likely not.  You'd have had to install a special add-on to enable it.

 


@starbase804 wrote:

Then the files are at risk.  If we get through this, I recommend putting a backup plan in place.

 

Are you seeing shares on the shares page?  If you are, then it might be possible to do a backup of your data (connecting an NTFS formatted USB drive to the NAS, and creating a backup job in frontview).

I don't believe USB recovery is a good idea right now, though I'd defer to Netgear support on that.  I don't know the cause of the OS Index issue, but I'm not seeing any indication in your symptoms that suggests the problem is in the flash memory.  It might be the OS partition on the disks, or it might be some other system failure.

 

But it sounds like you have rebooted the NAS (since you couldn't have tried the USB recovery w/o that).  Is that the case?  If so, did you check if DLNA was still working after the reboot?

 

On the main problem - one option is to use paid support (via my.netgear.com).  If data recovery is needed it would be expensive, but it is likely that they can solve your problem w/o that (since the data still seems to be there).

The data volume is completely full (which isn't a good idea), and the volume scan failure means there is some corruption of the file system.  So there likely is some data loss - hopefully not much.

 

Try booting the system w/o the volume check.  Instructions for that are on pages 23-24 of your hardware manual here: http://www.downloads.netgear.com/files/GDC/RND2110/Duov1_NV+v1_HW_en_06Dec11.pdf

 

If this works, then immediately back up your data - don't delay, and don't try to add or delete any files on the NAS.  The fastest way to back up the data is over an ethernet connection.  You can use drag-and-drop to a USB drive connected to your PC, or a utility that includes verification of the copy (I believe teracopy will do that).  If you don't have a USB drive,  start by copying the most important files to your PC (for instance, any personal photos or videos that can't be replaced).

It's possible that the OS partition is also full.  But try booting with the option to skip the volume check next.  The goal now is to extract the data, so you don't lose it.

Ok.  But did you try booting w/o the volume check as I suggested above?

There should at least be some difference in the log (failing for some other reason than the volume scan).  It might be helpful to know what that reason was.

 

You might consider using paid support for this (my.netgear.com).

So not even a "system powering off" when you shut it down...  I'm thinking you probably have a full OS partition on top of the full C volume.

 

Do you have any experience with the Linux command line interface?

Re: RND4000 Odd issue

years and years ago when i was a kid i played around a bit. old age has wiped most of that knowledge though. is there a way to safely delete some space? front lcd is showing 89G free which sounds about right.

Re: RND4000 Odd issue

You can't clean up from the OS partition unless you use the linux CLI.   That either requires ssh to be enabled in the web ui, or use of tech support mode from the boot menu.   My guess is that ssh isn't already enabled - and you shouldn't attempt to install the add-on required now.  So that would leave tech support mode.  

 

The overall process would be to log in, manually mount the OS partition, and (if it is full) search for the files that are filling it, and either truncate or delete them.  If you haven't used a command line interface for a long time, then it would be much safer to use paid support.  It'd be very easy to end up with a completely unbootable NAS - requiring a factory default to bring it back.  That would destroy all your data.

 

Let me know if you want to use paid support, or take the risk of destroying your data.

Re: RND4000 Odd issue

I've never needed it so I don't know for certain.  I think it depends on geography, and also if data recovery is needed.

 

My recollection is that per-incident support is less than $100 USD.  Data recovery is a lot more expensive (but wouldn't be needed if the issue is what I think it is).
