The number of total available 512 blocks is 38557496, so divide that number by 2 (half a kilobytes or 512 bytes) and you get 19M bytes, close to 18 Mbytes as mentioned above.
You didn't do this ?

To do it run touch /root/force_growfs then reboot.
or you did an nothing changed ?
Actually strange : the main advantage of using a VM is that you can do what you want with the file system, .... and you can't ?
These pfSense packages : acme, Openvpn-client-export, and Telegraf don't add use more disk space over time.
But Haproxy : I'm not sure.
Status_traffic_totals : I'm pretty sure this one produces a lot of data - and that is stored some where
Anyway : I still will advise you to use the ZFS file system, and the means a "re install" (with a VM that's a 5 minutes job if you have a slow machine ^^)
Hummm : the other partition knows as "swap" takes up the other 60-18=42 ?
There is also a third 'boot' partion, but that one is (should be) a couple of Megas max. -

Status_traffic_totals
For me running:
find /var/db/ -type d -ls | sort -n -rShowed that my ntopng and vnstat (aka Status_traffic_totals) databases were out of control. I have them nicely tamed now:

@RobbieTT This is my output in a txt-file because its to big...
What can I do with it, can I erase much of it? -
@RobinH said in Free Disk space >80%:
The packages I run is Acme, Haproxy, Openvpn-client-export, PfBlocker (disabled, not in use), system_patches, Telegraf and Status_traffic_totals

/var/db/ntopng ...
Did you have ntopng installed, and uninstalled it?
-
Your earlier output shows the total size of /var as 697MB. That's quite big but there is still ~11GB that seem to be unaccounted for.
-
@SteveITS ntopng is not installed, maybe it has been before.
-
@stephenw10 We have many OpenVPN tunnels, could that be it?
-
No VPNs don't really use any storage.
If ntop has been uninstalled then you can remove all those db entries for it in /var.
-
@stephenw10 Great, thats something :)
Is there a good way to remove the whole ntopng directory from /var/db/ ? -
You can do a recursive delete but it's...risky! Safer to remove the files inside that directory first.
-
@stephenw10 Okay, better not risk more than I have to. But everything inside /var/db/ntopng can be removed.
-
Yes.
-
I think ntopng has a GUI button to remove all the database entries, leaving you the uninstall and any remaining rm and rmdir after that.
I'm surprised how much space pfblockerNG took; mine is a mere fraction of that.
Still lots unaccounted for. The biggest user of space on mine is having version snapshots for different dev loads. The rest is trivial:
Good hunting.
️ -
@RobbieTT Yeah, I will uninstall the PfBlocker... not using it at all.
And will clear the ntopng files...

I presume this happens out there in the wild :
People install pfBlockerng, and start to try out all these : Firewall > pfBlockerNG > Feeds because "why not ?".
Soon, they'll discover that there is something as a resource limit, and not only disk space, but also that Xeon 8 core processor that goes hot read. An ARM won't make it at all ....All these 'feed' files initially downloaded, and their parsed and assembled counter parts will stay in the sub folders of this folder path /var/db/pfblockerng for until the end of days .... (or pfSense re install) or manual cleaning, as I don't think the /var/db/pfblockerng/. is emptied upon package removal. [ I have to try that one ... ]
Still, pfBlockerng is a small example. Processes (programs) that auto generate content are a real admin's nightmare - you have to watch them as you would do with babies. Even on big-iron-servers with loads of disk space (multiple T's) I do graph constantly free inodes and free disk blocks (disk space). Here is the same thing for my pfSense.File rotating for log files is the most straightforward example : as soon as my apache2 servers (or mail server) get swamped by requests, log files start to grow rapidly - like very fast. By simply launching multiple requests the server will steadily fill up its disk space, and then the classic game starts : what comes first : log rotation or server crash.

Tried this today, but it seems like there is no files there?

Did you manage to free any significant amount of space?

@stephenw10 No, I cant find the entries when i look in Var/db/ntopng

What does
du -h -d1 /show now?
