Jul 15, 2018OS 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" fail...

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.

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.

Jul 16, 2018Would 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
307.8M total
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.

eek...i thought I removed that app...it was an unwanted installed.
I just want a fresh OS install, clean of any apps, etc. to start fresh. I managed to get a working USB, yes older USB stick (2.0) worked, but same error as before after rebooting. I know some important/root directories/bin's had wrong permissions/owner changes that caused OS issues, etc so a OS wipe and reinstall was needed, but can't do it via USB Recovery due to that error above.

USB Flash recovery wouldn't have given you that anyway.
The only path I know of to do what you want is the factory reset (which unfortunately destroys your data).
