Cannot disable "DNS resolver"

[bbarzideh]

I would like to disable "DNS resolver" and run "DNS forwarder"
But when I try to disable it, or make any change to it, I got the following errors
The following input errors were detected:

The generated config file cannot be parsed by unbound. Please correct the following errors:
/var/unbound/test/unbound_server.pem: No such file or directory
[1533246902] unbound-checkconf[33259:0] fatal error: server-cert-file: "/var/unbound/test/unbound_server.pem" does not exist

PS. we cannot resolve any name from a client either when using the box as DNS.
But using this command will return and answer
nslookup cnn.com 8.8.8.8

Try to disable DNSSEC and/or try a reboot of the box.

So it seems the 30G drive is at %100.
What is the recommended Disk space?

pfSense only need a few gigs. A better question is how much space do you need? Based on your usage, I assume you're running a proxy(squid) and the proxy's cache is eating up all the HD you can throw at it. Trying to cache the entire internet?
