alright folks, let’s get real. we all have our sprawling digital fortresses, carefully constructed brick by brick. but there’s always that one piece of software, that one perfectly tuned instance, where if it so much as hiccuped, you’d be ready to throw the entire homelab out the window and start fresh in a cave. what is it for you? what’s your absolute, non-negotiable, ‘i will personally visit the datacenter if this fails’ self-hosted application? for me, it’s my media server stack. my wife would disown me. don’t let me down, arr suite.

ew, botposting
Is it? How do you know?
It’s hard to say exactly, it’s like noticing when something is CGI in a movie. It’s just kind of off.
The first few sentences gives it away for me. There’s also the filler words.
Also the way it rephrases the sentences. You have:
there’s always that one piece of software, that one perfectly tuned instance, where if it so much as hiccuped, you’d be ready to throw the entire homelab
Then again:
what’s your absolute, non-negotiable, ‘i will personally visit the datacenter if this fails’ self-hosted application
It’s also possible they just write like a bot.
Seconding the request for details - how do you know?
Thanks for the warning. To the blocklist it goes.
If you have a self hosted system and you throw the whole thing away because one service breaks you probably shouldn’t be hosting because you learnt nothing during the process
I don’t really have any of those. My stuff goes down and I later get around to restarting it. I’m a wimp in not self hosting more important stuff like email. But my media files are on a local disk rather than a server.

Well the only way my media server goes down is if the power is out for more than a few hours or my internet connection is down.
So I’d have to say that.
I don’t believe you, but I’d like to be proven wrong.
I expect you have a UPS that feeds your hosts and networking equipment and something like ZFS for disk redundancy. This protects against the most common failures and is usually enough, but there are still single points of failure in such a setup, that are not as common, not as hard to deal with through manual intervention, and quite difficult to protect with redundancy.
I would be surprised if you are protected against the following single points of failure without manual intervention:
- NAS machine (not just disk) failure. You would need to have a multi-node distributed storage, like Ceph, to protect against this.
- Networking equipment failure. I think you can do some magic with BGP to do this, but I’m not a network engineer and I’ve never set up a redundant network.
One thing I’d add is a whole house surge suppressor.
I saw the power lines arcing to either each other or the bamboo outside our house last week during a bad storm.
A whole house surge suppressor is only like $100, I’m gonna get one soon and install it. I saw it’s best to install it as close as possible to the main incoming power lugs, one lead on each leg of the split phase 120/240.
A UPS will protect against surges but it’s just a good idea with how many appliances and devices have circuit boards in homes these days. Like your furnace, oven, washing machine, game console, TV, etc.
I had an insane surge last winter so it’s a long time coming haha. I woke up and half my circuits were off. I measured 170v to gnd on one of the legs. Power company and fire dept had to show up to fix it.
Power is ehh not great where I live.
Edit: for your point about a NAS failure. If that were to happen, since I use unRAID, I could just throw the disks on any Linux PC and my data would be fine.
Ceph for the proxmox cluster, 2x48 port switch + 16 port 10gbit as the core, 2xNAS (technically one is the backup, and there would be a few moments of downtime as the containers restart - a different container with the same config pointed to the backup NAS instead).
UPS and internet are the SPoF.
Even Email can be down for two days or so without major consequences, and I could pull that up from backups on a spare server in another location within an hour max.
