Hello,
I've recently had some trouble with my router, which resulted in me factory resetting the modem and the router, which finally gave me the push to look through everything and see if it was running as it should.
I saw a message in the web interfalce telling mere there is a disk shortage. It didn't tell me much more than that. I've had a pihole running for some time, so it occured to me that this is the first time i've seen this message and there might be a problem that should be solved.
I tried to solve it myself, by following this post: Disk shortage (/var/log/pihole/FTL.log) ahead: 99% used
But the comments were going down a path that did not fit my problem, i think, since cron is running. I also tried looking through some of the other posts regarding the same problem, but it seems the problems are very unique/specific with this as a common symptom, which makes total sense.
I don't know what to do or look for. I've hopefully pasted output for 2 commands under this, correctly, which i think might be helpful.
