High Availability Pi-Hole? Yes please!

Dear Pi-Hole,
We love your product. It keeps our network safe from malware and other unwanted domains. While we love what is there so far, please add a feature to your core product to keep multiple servers in sync and provide high availability DNS to our whole entire network. Then, we won't have people asking us "Is the internet down?" every time we reboot our Pi-Hole server. Until then, we will use Gravity Sync.

Sincerely,
Techno Tim (and probably thousands of other lovers of Pi-Hole).

P.S. Keep up the good work!

Thank you Gravity Sync!

(don't forget to star the repo!)

Thank you for watching!

How are you running Pi-Hole at home? Raspberry Pi? Bare metal? Containerized? Virtual machine?

Let's face it: Linus Tech Tips and others are fun and informative, but I really do appreciate TechnoTim even higher. The content is rich in information while staying easy to understand (also proper video length), the quality and topics are uniform between videos and even the audiovisuals are more than enough. Thanks Tim!

"Pull" should be the default. It's the proper way because this way you have a "Source of Truth".

That intro is absolutely hilarious! Just had that same scenario play out this morning at my house. I will show this to my bride. Doubt she will see the humor tho as her client call was interrupted due to said scenario. Maybe I'll wait til the weekend. Anyway, thanks for the laugh Tim! And great video, as always.

I had Pi-hole running on a pie 3b+ for the longest time, without fail. It's now sitting on the desk as it's pfsense replacement is doing the work. Not as easy to configure but also stable. IT's all about what platform you want to run the lists on. I like the little pies for their low energy use and powerful platform. Thanks for another good Video.

Tim, I hope you keep doing these videos, you deserve a much bigger audience. Your content is great!

[bzr]

Excellent tutorial! Taking your lead, I bought a RPi Zero 2 W as a secondary backup and now have two running! Once I manage to get a third Pi, next step is to mess with the VIPs :)

Great video TT!
Have been running a single pi-hole at home for around 10 months on an Rpi4 and have it booting from a USB.
I came across this video and instantly ordered a second Rpi4 and used the PI's SD card copier app to copy the 1st's USB.
Booted up, changed the IP address and hostname as needed and then stepped through your video.
Could not have been any easier!
There were a few questions/options different from your video to now, but i just accepted the defaults until I caught up to your instruction or your instructions caught up to what i was seeing on the secondary Pi.

Oh my word. That intro was so spot on with how it goes at my house :D

[ryanmalone]

That intro sketch is a perfect simulation of me answering any and all questions asked by the family about the network.

[juanjosebora]

Awesome video! It helped me a lot!

Do keep in mind that you don't need to reboot when you change visudo.

[naami]

A new Techno Tim video !! that's exactly what I needed :) thank you

[majorgear]

Years later, we still have to use gravity sync . I just set mine up today. It was easy peasy !

I do like not having to export/import setting every time I change the primary, which is how I kept them in sync before.

[Jay.M]

Your videos have been improving a lot lately. Your channel is going to grow fast, great work!

[gpoleze]

I've been running my Pihole on Kubernetes and using persistent volume pointing to my NAS. However, I have never checked if I would have any kind of issues scaling it up to more than one pod. PS.: Thank you. Both the my K8S Pihole and Proxmox VM TrueNAS were based on your videos.

[Aastan]

This gets video of the year for me. Man, why did I not think of running dual Pi-holes a year ago?

[ricardorocha]

Nice work once again, loved the funny beginning of the video :) Hope they implement a nice and easy sync solution on Pi-Hole.

[chrisumali]

Thanks for the info and demo, that dialog in the beginning is hilarious

[hprompt]

run 2 pihole containers on my proxmox servers, the first shows queries, but the second one doesn't. this information is what I needed

Hey Tim I love the pinhole I’m using it from past one year it’s works like a charm I live in a gated community which has 12 houses People from all 12 houses share the internet bill we have a switch installed to distribute internet I had a pi 0 I setup Pi-hole in it and put it to our network daily it Blocks around 5000ads it’s amazing
