GUI shows Low Hard drive usage but Plugins failing because there is no space

[awptechnologies]

Posted this in issues on github but no response figured i would see if anyone on here has had the same issues!

So it seems that my insight aggregator and ntopng plugins were failing because the system was out of hard drive space. Once i looked into logs i could see that they were telling me that very blatantly. I wanted to make sure so i disabled my ntopng deleted the data directory in /var/db. I also reset netflow data and rrd data. After doing this everything is running again. The part that confuses me is the disk usage on the GUI dashboard showed i was only using 60% of my hard drive. Why would it show this if the hard drive was that full?

To Reproduce

Steps to reproduce the behavior:

    Go to GUI dashboard and look at disk usage.

Expected behavior

I would expect the GUI to show the correct disk space usage.

Describe alternatives you considered

Maybe the GUI is not pulling from the right data.

The output of the "df" command once the system is in that state would help to diagnose what's wrong.

I agree after doing df -h i saw the percentage used matches so now I'm wondering why logs and plugins that use data base are showing errors about storage when the system had 40% of space left. Is there some kind of limit set in the OS?

Is there some kind of limit set in the OS?

No. But if you have a RAM disk enabled under System > Settings > Miscellaneous you might have filled up that.

Nothing is enabled in those options. https://gitea.awptechnologies.co/awptechnologies/OPNsense-Dev/src/branch/main/OPNsense-ramdisk.png
