ReadyNAS R102 lost connection, root volume 100%, antivirus won't enable, etc.
Bought my NAS a few years ago to do TimeMachine backups and to archive photos and videos. It's mostly been working ok until recently, when it disappeared from the Finder in my MacBook Pro. Upon inves...
A full root volume will cause a variety of symptoms, including corrupting the configuration files on the NAS (because they cannot be rewritten if there is no space in the OS partition). Attempting to restart services or (like AV) increases the risk of this kind of damage. So does changing the system configuration.
Paid support can clean it remotely, so you might consider paid support (my.netgear.com) for this. Ask about per-incident support.
If you have ssh enabled and are skilled with the linux cli then you could attempt to diagnose/fix it yourself. Or do a factory reset (which will destroy all the data on the NAS), and then reconfigure it, and restore the data (other than the TM backups) from a backup.
Thanks very much for the information. Sounds like I might be best to do a factory reset, as I've got most of the data backed up in other locations, and it shouldn't be too painful to download the other 300GB or so using the web interface (since I couldn't get NAS to recognise and format a USB drive for a directly connected backup of the other folders).
My question at this point is: how do I prevent this issue happening again in the future? Is this caused by enabling apps on the NAS, or what?

Apps currently in the app store shouldn't do this, but some older ones might have. If you install packages using ssh, then you do need to be careful not to put too much in the root partition.
There are a several other possibilities - sometimes a problem can flood the logs (which are stored on the OS partition). I've sometimes seen cases where data that was supposed to be backed up to a USB drive ended up on the root volume - perhaps due to a failure to mount the drive properly.

There are lots of failure modes where RAID isn't enough. So after you've recovered from this, you might want to put a backup plan in place for the NAS.
I've just about completed restoration of the NAS to its proper state. Regarding a NAS backup plan, I think I'll sync my critical NAS files (family photos, video, documents, etc.) with a cloud service like Dropbox from now on, in case of future issues with the NAS or disaster that takes out physical devices onsite. It's probably worth the money given the peace of mind and accessibility it provides. Thanks for the insights and recommendations, much appreciated.
