System volume 'root' usage is 100 %
I have been getting the 'System volume 'root' usage is 100 %' messages every 10 minutes for the last month now. I tried working with NetGear ticket support but when they escalated my ticket to su...

# rm -rf /btsync
Seeing you no longer have that app installed I have deleted the folder.
It is important that any app you install is configured to store data on the data volume somewhere. The 'root' volume is 4GB so if you configure an app incorrectly you can fill it fast.
How did you delete it?
Did you verify that it is not there using terminal?
Can you run the df command as above and post the result .
if there is space on the OS partition it may be worth doing an OS reinstall now, but you must first verify that you have cleared some space. Doing an OS reinstall if the OS partition is still full will likely make the problem worse.
Do you have a backup?
I deleted the folder via the web GUI.
I ran the terminal command you listed above. Here are the results:
This was from the df -h command:

rootfs 4.0G 3.9G 0 100% / <-- is this telling me there is still 3.9GB of data in rootfs?
All the files and folders on this NAS are not totally backed up. Some are. I'll have to back that data up before doing an OS install.
Thanks again for your help.
Joe
That indicates that the OS partition is still full.
The file that mdgm indicated is very large, how did you delete this from the gui?
You probably need to delete it using the terminal window.
DO NOT do an OS reinstall now. It will almost certainly fail and create a bigger problem.
A factory default is one option here but this wipes the disks and seems excessive when you can just delet e the btsync folder.
If you type in the terminal window
cd / ls -a
What is the output?
you can also run commands like:
# du -csh /var/* # du -csh /var/log/* # du -csh /var/log/frontview/*
These may identify where the offending folder/ file is located. You will get an output with folder sizes
Alternatively wait for mdgm and he can perhaps remotely delete it for you - I'm assuming he diagnosed this by accessing your nas. I think he may just want confirmation from you that you are happy for that folder and/or it's contents can be relocated or deleted.

It is important that any app you install is configured to store data on the data volume somewhere. The 'root' volume is 4GB so if you configure an app incorrectly you can fill it fast.I'd like to thank everyone, and especially mdgm, for your help with this issue.
It is now resolved.
I'm surprised Bittorrent Sync installed in the root directory. How do I avoid this in the future if an app installs its folder in the root directory? Is it just a matter of using ssh to move the folder elsewhere?
Thanks,
Joe
