On another thread, Netgear said they'd be starting a 6.7.0 beta very soon to roll out AV fixes.

Others have reported the NAS incorrectly reporting a problem with a share when it's the OS partition that's almost full, and that sounds like your problem. There are several things that can cause it. But you need to check before it gets completely full and you are unable to access Frontview.
Currently, the only way to check/fix a filling OS partition is via SSH (and tech support mode, I thnk) and some knowlege of Unix or specific directions. I have put in a suggestion that better tools be provided for preventing and fixing this issue. There are a number of existing message chains on this subject.

I am getting this warning regularly for the past couple of days on my RN214: "System volume root's usage is 95%. This condition should not occur in normal conditions. Contact technical support." Is this the same thing? ( I am also getting the less than 5% free warning).
I was getting it on OS v6.6.0 and after upgrading to v6.6.1
I have linux-dash installed and I see this:
Disk UsageFilesystem Size Used Avail Use% Mounted/dev/md0 3.7G 3.5G 0 100% / /dev/md127 11T 2.6T 8.4T 24% /data /dev/md127 11T 2.6T 8.4T 24% /home /dev/md127 11T 2.6T 8.4T 24% /apps tmpfs 1009M 0 1009M 0% /dev/shm I can see that it is /dev/md0 that is reporting to be full, what can I do about it? I am OK with SSHing and Linux command line, but I don't know what commands I need to use.
Can anyone help please?
Regards,
Paul

You can use du to locate where the space is used. This situation (full root) can occur for different reasons, most common ones are applications installed from backend (like mysql or crashplan), log files that aren't rotated (added by apps), etc.
1. cd into the path you want to analyze first
2. du tells you where the space is used
3. cd into biggest folder
4. du
5. Repeat until you find the folder containing the files, then use ls
# cd / # du -d1 -hx . -> var is the biggest # cd var # du -d1 -hx . -> log is the biggest # cd log # du -d1 -hx . -> current folder only is big # ls -alh

The step by step approach is interesting to analyze the filesystem usage. But there are shortcuts available, like this one:
du -hx / | sort -hr | head -n 10
If the first line doesn't show 4GB, then there might some data in a folder that is not readible using du (for example, /data, but not on the data volume, on the OS volume ; data that was created under the mountpoint path before the other volume was mounted).
