WARNING - Firmware Update 6.9.0
So, my NAS promted me to tell me that a firmware update was available and, upkeeping with the latest versions, I decided to go ahead and do the update via the web browser. Seems painless ... Aft...
You didn't told us which is the ReadyNAS OS software version that your NAS was running before the upgrade request to download and install latest ReadyNAS OS 6.9.0...also doing preliminary checking - through SSH - of most important log files would be helpful to understand what happened during/after the update (and Yes...knowing where to look for is important to have a smooth start...ranting isn't helpful).
These symptoms are consistent with an app wrongly changing the ownership of folders/files that it shouldn’t rather than a firmware issue.
Which apps do you have installed?
Here is an extract of the fwbroker.log:

As for what happened next, who knows. What I can say is, the NAS worked fine before, and after the update doesn't!
But hey, here's the question: why woud the /var, /sys, /etc directories need to be owned by guest? They wouldn't. If the config files for these services isn't owned by root (or at least admin) then none of the services will work.
Apology for the rant, but yeah, after what should be a simple a update, needing to spend a week on data recovery does tend put you in a bad mood :-)
Kudos
Again, this is consistent with a bad app, not a problem with the firmware. This is my experience from every time I’ve seen a customer have this issue.
Just seen this comment.
Only App I run on the NAS is Plex Media (had it running for years) to stream Music/Video around the House. It runs seemlessly in the background, with little (if any) effort needed to maintain.
Only other App I've looked at is Rsyslog to see if I can make any use of it. Rsyslog was installed from the NAS app store and, after checking, removed because I can't make any use of it.
If this were App related, then suppose fundementally the question would be how did an App get into the Netgear App store that has the potential to not only break the NAS, but change the permissions on every single file/folder on the device? Surely they're tested to make sure they don't introduce such critical vulnerability before being released?
If not App related, then the point still stands re Firmware update.
