NAS RN212 Cannot access Admin Page

NAS RN212 Cannot access Admin Page

The RN212 is up and running.  I can access the drives from Windows File Explorer.

When trying to access through web browser to get to the admin page I get the Netgear splash screen then goes blank.

I have rebooted the NAS twice and closed and opened the browser.  Same results.  The log in credentials are working but the screen will not populate.  Also I do get the progress bar as if it is opening but goes back to password screen.

Have you tried downloading the log zip file with RAIDar?

Do you have access to the files?

If you do, it would be prudent to back up the NAS

Re: NAS RN212 Cannot access Admin Page

I accessed through RAIDar.  It found my NAS.  I started the log file download and it stopped at 14%.  I tried re-initializing the download and now RAIDar cannot access my NAS. Also, Windows File Explorer can see all of the folders and files but I cannot open some of the files.  I can open text and Excel files.  Most of the others cannot be opened.  Legacy is extreme long.

Do you have a backup of the files?

Re: NAS RN212 Cannot access Admin Page

No, this was my backup.  The original source is being rebuilt right now.  I backed up everything to this NAS while the other was being rebuilt.

Ouch.  So no files on the original source now?

 

If you have experience with linux, you could also do some more diagnosis after booting the NAS in tech support mode. But now is probably not the time to try and learn linux.

 

You might want to go with RAID recovery.  You'd need a package that support BTRFS.  Generally the recovery software runs on a Windows PC.

  • You would need to connect the disks either with SATA or a USB/adapter dock.  There are several two-bay docks that would work.
  • ReclaiMe is one software package several folks here have used with some success. Unfortunately it is fairly expensive.

Re: NAS RN212 Cannot access Admin Page

It sounds like you may have a full OS partition.  If it was nearly full, creation of the log may have finished filling it.

That is something that can be fixed if you have some experience with the linux command line interface.

I haven't used Linux in many years.  Not comfortably familiar.

Re: NAS RN212 Cannot access Admin Page

Also, I had turned on Snapshot on a couple of the folders.  I noticed that it took up alot of space.  But I'm unable to access the Admin Page to delete the Snapshots.

The OS partition is separate from the data volume, so the snapshots shouldn't be causing your admin page issue.  FWIW, I do use snapshots myself, but I use the custom snapshot settings with limited retention.  I find that makes it easier to control the amount of space they use.

Re: NAS RN212 Cannot access Admin Page

So I need reduce space on the OS partition.  How do I go about that?

Message 12 of 30

Re: NAS RN212 Cannot access Admin Page

  1. Have you installed any apps on the NAS?  If so, which ones?
  2. Do you know what firmware you are running?

@RichardB56 wrote:

You'd need to boot the NAS in tech support mode, and then connect using telnet with a backdoor password.

 

Once in, you'd need to figure out what was taking up the space using linux commands, and delete the unneeded files that are filling it.  I can post the space use from my own NAS to give you a basis for comparison.

 

You might then need to run a repair tool to restore missing configuration files.

 

If you want to proceed, let me know and I can give some more details to get you started.  Then as you proceed, I can try to give you some more steps (based on what you find).

Re: NAS RN212 Cannot access Admin Page

No apps as far as I know.  I was only using it as back up for my primary NAS.

Firmware updated a couple of weeks ago to 6.10.10

Would connecting via USB help?

I need to what ever it takes to recover what is on this NAS.  I had the reformat my primary.  The Netgear was my back up for it.  This data is not stored anywhere else.

Re: NAS RN212 Cannot access Admin Page

Would rebooting into OS reinstall help?

Or Volume Read only?  Just to recover the data.

None of these would help, and they could make things worse.  Rebooting (into any mode) could result in losing access to the files from the PC - which I think you still can do??

 

If I am correct that you can still access the files Windows File Explorer, then the safest path is to copy the files using the PC.  You could copy them back to the primary that way, or other storage.  Once the files are preserved, we can revisit  options to get the RN212 working properly again.

Re: NAS RN212 Cannot access Admin Page

No. I cannot access the files any longer.  I can see the folders and files in Windows File Explorer but cannot open or copy any of them.  If I try to copy the files it appears that the NAS loses network access, even RAIDar loses connection.  The copy process fails and then access by RAIDar resumes.

Additional information.  I tried moving the network cable to the 2nd network port and it would not connect.  I tried another cable with the same results.  First port connects and pulls an IP.

Ok.  

 

Options are to

  1. use RAID recovery software
  2. try to mount one of the disks in a different linux system. 
  3. use tech support mode to try to troubleshoot the NAS

On (3), a full OS partition is just a theory at this point, it might be something else.

 

In any event, (3) is riskier than 1 or 2.

 

Which path do you think makes the most sense for you?

Re: NAS RN212 Cannot access Admin Page

1. I went to the Netgear download page, no recovery software.  Are you referring to another off-software app?

2. I have a Synology NAS and a SDD reader.  Its been over 10 years since I used Linux.  I'm not sure where to start.

 

What if I pulled the SDDs from the unit.  Put in a HDD I have and troubleshoot that way.  If repaired I can remount the SDDs.

The system boots from the disks, and all the configuration, etc is on the disks.  There is no way to troubleshoot this with different disks in the NAS

We can try to give you advice as you go, but it would be slow, and there would be risk of data loss.

Re: NAS RN212 Cannot access Admin Page

The more you list your symptoms, the more it does sound like a full OS partition.  It could be just a corrupt one, but doing a re-install without first verifying it's not full is a very good way to make things worse.

 

How did you transfer the files you backed up to it, via the network or from a USB drive.  We have seen issues reported here where others have had a USB drive disconnect during a transfer, resulting in files going onto the OS partition instead of the USB drive because the mount point ends up being treated as the destination instead of the mounted drive.

 

Is SSH enabled on the NAS?  You may be able to get to your files and transfer them back to your primary NAS or an external drive using SSH.  You may also be able to free space on the OS partition via SSH.

 

You asked if accessing via USB would help -- the ReadyNAS cannot be accessed by USB.

@RichardB56  That is a likely cause, and something that isn't that hard to check.  But it can take some time to track down the files that need to be deleted.  It would require booting the NAS in tech support mode, and systematically looking for folders that have too much data.  After the OS space is freed up, there might be other actions that are needed to restore config files.

 

FWIW, when folks are doing this, I often post what the folders on my own NAS show, which can help in tracking down the problem.

 

I am thinking it could also be two failing disk drives.

Re: NAS RN212 Cannot access Admin Page

Thanks.

When I backed up from the Synology NAS to the Netgear NAS i did it via Windows File Explorer, not by USB drive.  Copied folder and files.

I do not know know if SSH is enabled on the Netgear.  I cannot access the Admin Page to check.

Re: NAS RN212 Cannot access Admin Page

I installed 2 new SDDs in about 2 months ago.  I was rebuilding as the back-up for the Synology NAS.  

Which would be less riskier; RAID Recovery software to remove files or enter Tech Support Mode to look at the OS partition?  This knowing my Linux handicap.
