RN3138: cannot change IP/DNS setting

Hi,

Ok so we changed our DNS servers at our business so now I have to change them in the ReadyNAS. Obviously I log into the UI, go to the network tab, select the settings from the gear of the bonded network interface (all 4 are bonded), select IPv4 and configure the new DNS server IP along with the search domain. I apply but when I return nothing has changed; old configuration is back!

I log via SSH and check the resolv.conf file has not changed so I'm sure it's not a visual glitch.

Another NAS, same make and model, at our DR site does not have this problem.

Any ideas how to fix this? I tried rebooting already.

We're running the latest firmware 6.10.2

Did the OS reinstall but still no connectivity... either that doesn't reset the network stack or I did something wrong

An OS reinstall will

set the network stack to use DHCP, MTU of 1500, with no bonding

set the admin password to password

turn off volume quota (which is on the volume settings wheel).

Instructions are on pages 44-46 here: http://www.downloads.netgear.com/files/GDC/RN2120/ReadyNAS_OS6_Rackmount_HWM_EN.pdf

Hi Casgrain,

Welcome to the Community!

You can try first downloading the NAS system logs and then check the volume.log to see if the OS partition is full.

If it is not full, you can try doing an OS reinstall and see if it fixes the issue. You may check this article for the steps on how to access the boot menu and select the OS reinstall option.

  I deleted the bonding in hopes recreating it would fix the issue but now I have no connectivity to the machine... RAIDar shows the same IP as before but no way to reach the UI or even ping it...
  
  The sotrage isn't full I'm sure of that. I'll try your OS reinstall method and let you know.
  
  If I have to factory reset the device you can be sure we'll never buy a netgear product again

    The OS partition isn't part of the data volume. So it can be full even if there is plenty of space in the data volume.
    
    You might try downloading the log zip file before you do the OS reinstall. If that works, then look at volume.log. Scroll down to the section that looks like
    
    === df -h === Filesystem Size Used Avail Use% Mounted on udev 10M 4.0K 10M 1% /dev /dev/md0 4.0G 672M 3.0G 19% / tmpfs 1.9G 0 1.9G 0% /dev/shm
    ...
    
    /dev/md0 is the OS partition, and it normally is ~20-25% full.
