Setting up Pi-hole

sounds like what happened when the SDcard died in my RPI1b, if you get a chance give "sudo apt autoremove" a go to see if it would make any difference.

That seemed to do something. It cleared 800kb of space, I rebooted it, and I can now access the GUI. Updating didn't work, but according to the GUI I'm up to date anyway.

What can I do to stop it filling up again? I assume it's the logs it's keeping?

Just checked the disk usage, I'm 99% full! That's the problem.

Code:

pi@raspberrypi:~ $ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root        11G   11G  119M  99% /

tmpfs           464M   40K  463M   1% /dev/shm
tmpfs           464M   13M  452M   3% /run

What size memory card is it? By default the logs are stored in ram to reduce disk writes.

Have you installed a GUI or running cli only? No point installing GUI if only running cli just uses up disk space.

It's 16GB. I did install a GUI to set it all up before I discovered I could connect with Putty and use commands.

I suppose I should start again with command only? Will that still give the web GUI?

yeah you still get the web interface, no need for a GUI if all its doing is running pihole, I would take an image of the SDCard as it is now (I use win32Diskimager on a Windows Machine or DD on linux) then put a fresh version of Raspian on there with no GUI, you can strip the drive image down and not install half the stuff that it comes with at default, I was only using an 8gb card and raspian with pihole installed was less than 1gb in total.

Thanks, I'll add to my to do list for the weekend.

Look to see if there is a command to remove the GUI. You could take a look at Raspbian lite and Diet Pi is also another option. It comes as a GUI by default but it is more light-weight than even Raspbian lite. Appears you can even remove the GUI on it with a command to use even less resources.

I always use Raspbian Lite for this sort of thing - Looking at my two Piholes now, the free space has barely changed since I set them up so I don't know what's using your space. Is the Pi doing anything else?

This is what is confusing me. Pi hole runs cleanup and update tasks at stupid oclock every day so it shouldn't be using loads of space.
i run raspbian, pi hole, vnc, deluged, kodi etc etc, and a usb HD from my pi3 and the disk usage on the SD card is pretty static.
resources when using pihole on a pi should not be issue. at most it uses about 8-10% of the cpu and thats when i am hammering my net from mutliple devices.

It's only used for Pi-Hole. I'll do some research and see what I can do.

Just tried to access Pi-Hole web GUI and it unavailable again.

Code:

pi@raspberrypi:~ $ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/root        11G   11G     0 100% /

tmpfs            93M     0   93M   0% /run/user/1000

That's what has changed.

What are you running as root? Why is the root partition 11gb and full?

mushtafa · 14 Nov 2019 at 22:54

I've no idea. I followed a guide to install Pi-Hole, I don't really know what I'm doing. If there's any commands I can run to give you that info let me know

Feek · 15 Nov 2019 at 13:13

To give you an idea, this is one of mine:

Code:

Filesystem      Size  Used Avail Use% Mounted on
/dev/root        15G  1.8G   12G  13% /
devtmpfs        213M     0  213M   0% /dev
tmpfs           217M  2.4M  214M   2% /dev/shm

tmpfs           5.0M  4.0K  5.0M   1% /run/lock
tmpfs           217M     0  217M   0% /sys/fs/cgroup
/dev/mmcblk0p1  253M   41M  212M  16% /boot
tmpfs            44M     0   44M   0% /run/user/999

For sometime now, my pihole is saying "lost connection to API"
anyone know why?

Log in and do a pihole -up to update it, this should fix that issue.

In that case do pihole reconfigure and do.it all from the start, it does have a static IP yeah?

yes it does have a static IP.
Will reconfig, thank you

That's because it's trying to use itself for DNS resolution and as Pi-Hole isn't working it has no working DNS.

I've had this before and just wiped the SD card and did a fresh installation. If there's nothing else on the Pi that'll be the quicker route to get it up and running again.

mushtafa · 16 Nov 2019 at 14:45

Got round to sorting my space issue out today.

Started from scratch, new install of Rasbian Buster Lite, no GUI, and fresh Pi-Hole installation.

Will keep an eye on space used, hopefully it won't change too much.

Thanks for all the help on this.

pi@raspberrypi:~ $ df -h

I've set up PiHole and in using it on a device by device basis. Got it successfully set up on my Linux machine but trying to get my Pixel 3 to run it is a nightmare.

Whenever I enter the DNS manually on my Pixel it gives me "Connected, no internet"

I've read IPv6 can be a problem but I've had that disabled since forever.

Any advice?
