OS Reinstall issues
Hi, I just tried to re-install the NAS OS via the Boot Menu (using option 3 in the Boot Menu Options), but it appears to have failed:
LCD msg: "Updating FW"
LCD msg: "ERR: Could not extract" failure
LCD msg: "lcd_panic_handler+7d" stops on every reboot now....
I've had a look at prior forums, it appears the Boot Menu OS reinstall is broken?? (isn't the f/w updated by Neatgear on each main rversion F/W release?)
Anyone know why an OS reinstall wont work from the Boot Menu? F/w OS file corrupt/old?
More so, how can I reinstall the OS on the NAS without wiping all the data drives (do I have to do a USB OS Install )? (I was running O6.9.3 just prior).
An OS Re-install installs the OS over the top of itself, resets some network settings and the admin password. It doesn't wipe your logs or configuration which can be vital when troubleshooting problems.
A factory reset (wipes all data, settings, everything) and creates the RAID, does a clean install of the OS, creates a new data volume etc.
There is of course a way to manually wipe the 4GB root volume which I have now done this once for you.

Hi Retired_Member
You can do OS Boot Recovery without wiping the data.
You can follow this article USB Boot Recovery You may have to get a few flash disks ready.

Hope this helps!

I've created the USB Boot image with the latest OS img in the x86 folder, powered the NAS to boot from USB ("OK" for 30+ secs) and LCD displays "booting for external USB", but no changes for over an hour. Does the USB Utility do some kind of h/d check? (I have a very large array). Will it self shutdown once completed?
Have you tried changing flash drives? There are times that the flash drives are the cause of the recovery not to complete.
It should shutdown its self once the recovery is complete. I would suggest using a different USB drive
The USB Boot Recovery tool is provided for free. Not all USB keys are compatible so it is worth trying different USB keys.
"ERR: Could not extract" is a possible symptom of a full 4GB root volume.
USB Boot Recovery only helps if the problem is on the internal flash. It's possible that this might not be the case here.
USB Boot Recovery doesn't touch the disks though if the firmware loaded by USB Boot Recovery is different to what's on the disks the NAS will correct the firmware mismatch on the next boot.
I've sent you a PM.
Would be useful info identifying which or what type of USB Sticks are compatible (ie it only states FAT32 no larger than 32GB in size, no extra partitions - no inditication of manufacturer, USB type 2/3/3.1/etc logical/physical partition type, active/boot status, etc..)
If OS size being full is such a critical issue, then the devs should have a warning/metric to show how full it is, preferably via WebGUI (at the very least), let alone a better way to manage the OS space (dump non-OS/NG core components elsewhere)
Thanks mdgm for your assistance, the community forum responses is one reason I've stayed with Netgear (not just with NAS solutions).
I think older ones are probably more likely to be compatible. The tool is designed for USB keys with a single MBR partition using the FAT32 filesystem.
Your 4GB root partition is very full
# df -h
Filesystem Size Used Available Use% Mounted on
/dev/md0 4.0G 2.7G 1.3G 68% /
The main culprit appears to be the meteor app
# du -csh /root/.meteor
937.5M /root/.meteor
937.5M total
# du -csh /tmp/mt*
300.0K /tmp/mt-161hu49
252.0K /tmp/mt-18gkr8d
306.5M /tmp/mt-1udi31b.z15x
132.0K /tmp/mt-1ywalx3
332.0K /tmp/mt-4wqahx
228.0K /tmp/mt-784xps

Apps need to store their data on the data volume not on the 4GB root volume.
Once you've moved the data across to the data volume and created a symlink or modified the configuration of the app then an OS Re-install should get your system back up and running.
Obviously you can't move the /tmp directory, but hopefully the app can be configured to store it's temporary data on the data volume.
