Cache Floor Size error

[staunts]

Morning all, 

not sure if related but I have recently installed PiHole and started getting this error overnight. I don't have a cache drive installed - just a parity and 3 other drives.

 

"Cache Floor Size (calculated to 2048000000 bytes) is larger than your cache drive (1953566720 bytes)"

any ideas  ?

cheers, Adam

Is that error from FCP? If yes best to post in the plugin support thread together with the diagnostics.

You have a docker container that is referencing (probably it's /config appdata path) /mnt/cache instead of /mnt/diskX or /mnt/user

 

This is creating the appdata for the container in RAM, and since /mnt/cache exists, FCP is running that test.  You're going to wind up with other issues until you change that (besides the fact that whatever container is doing this, it's appdata will get lost on every reboot of the server)

Thanks guys. I'm a bit of a newbie with all this. I see what you are saying, see below. Do I just change the /mnt/cache/ below to /mnt/user/appdata/ ? Will that just fix it or will I lose config/data ?

 

/etc/dnsmasq.d//mnt/cache/appdata/pihole/dnsmasq.d/
/etc/pihole//mnt/cache/appdata/pihole/pihole/

Just changing it won't do anything at all to preserve the appdata that you have already accidentally created in RAM. It will create new appdata on actual storage.
