@krillin666 which operating system are you using? Are you running Pi-hole in a docker container? How does df -h look like?

Hi @DL6ER , I'm running raspbian OS. Running df -h i get:

Are you running Pi-hole in docker? If not - then please open a thread on discourse.pi-hole.net

This thread is to track a specific issue with this warning showing up in docker containers

I sort of moved your issue over here, unfortunately, Github doesn't allow to really isolate + move posts when it is appropriate.

As you df snippt shows, you are not affected by any bug. Indeed the warning is correct as the default is to warn if more than 90% of disk space is used, for your it is 95%:

Filesystem      Size  Used Avail Use% Mounted on
/dev/root       440G  398G   25G  95% /

You can either increase the limit to silence the warning until you hit again a threshold (say CHECK_DISK=98) or disable the check altogether (not recommended, but possible with CHECK_DISK=0). See here for more information.
