Run:

df -h

in the terminal and find out.

Not NEW, but, check out local auctions. Local universities and govt offices are frequently selling lots of newish laptops (5ish yrs old) for $10-$50 apiece.

That’s why we have mice copy/paste bindings on most systems too. Highlighting text auto copies, and scroll wheel click pastes. Not all do this, but many do and have for a while.

Great, I recommend having two Adguard Home instances.

Yep, if you have somewhere to put a docker container or VM you can have redundancy.

Right, I never said two raspberry pis, I meant two instances. Like one pi and a container run elsewhere.

Right, I didn’t have any issues running it on a pi for years too. The problems came when I started messing with things. So, really my advice is to help save people from ideas like mine.

I decided one day to take a bunch of old laptops and create a proxmox cluster out of them. It worked great, but I didn’t have a use for them, I was just playing. So, I decided to retire the pi and put the pihole on the cluster. HA for the win!

I did that and came woke up a few days later to my family complaining that they had no internet. I found the pihole container on a different node and it wouldn’t start. Turns out with proxmox you need separate storage for HA to work. I had assumed that it would be similar to jboss clustering which I’m familiar with, and the container would be on all the nodes and only one actice at a time, with some syncing between nodes. Nope.

What’s worse is the container refused to move back to the origional node AND wouldn’t start. The pi was stored away at this point so I figured it would be easier to just create a new container, but duh, no internet. Turn off dns settings on the router, bam have internet.

Eventually set up the old pi again, and it took me a while to figure out what I had done wrong with proxmox. But while I was figuring it out it was nice to have the backup.

Now I always have two running on different hardware, just in case.

I recommend having two. Otherwise your home internet goes down everytime you update or reboot or it crashes.

Or to hang on a home server rack displaying dashboards.
