This is why we have UPS ;-)
Seriously, one black out and suddenly you see the need for a UPS. Now my desktop is on a USB, my work laptop and monitors are on a UPS, my homelab is on a UPS, even my modem and router are on a UPS. I just wish I could get a backup generator, but that's not happening anytime soon.
My experience with using an UPS is that they have caised an outage every few years, which is more often than we get power outages where I live, so I didn't replace the batteries last time the UPS took down my server, and are just running straight from the wall. It might be better with a more expensive UPS, but it's not worth it for me.
I got tired of my network puking every time the power went out for 5 seconds.
Edit- My NAS really dislikes having the power cut off.
Yep, the black outs have stopped now but for a while it was a daily occurrence. My NAS took a beating and so did my desktop. I spent a ton on ups's to make sure that stuff was protected and bonus, I wouldn't loose connection while on phone calls with government officials while at work.... they get pissy when you suddenly drop off.
My father was an HPUX admin that had a server with an uptime of >12 years
I was introduced to homelab by trying to figure out how my uncles setup. It ran for 4 years after he died, 11 years uptime. The estate probate prevented anyone from touching the equipment for the legal fights, and I get a kick out of thinking of how smug he would have been about it.
Heard of tuptime? I've been using it for a while now, I think I like it.

So, you never update the kernel?
Mine's not connected to the internet so I'm utilizing the if it ain't broke don't fix it strategy.
At least in my experience the chances that I move or replace hardware are much higher than the chances for a power outage.
Pretty sure everybody is missing the joke. The joke is that Debian packages are so stable and stale that you likely will need a reboot before an update.
Also, it's a joke....please patch your boxes, k?
I've got a patch in my boxers right now.
Oh boxes.
Are we not doing kernel upgrades?
Was about to say, "or if you're running Arch, the last time you updated the kernel or systemd version, so probably last week or summit."
Or if you have a UPS and backup generator or a house battery (do these need a UPS as well still?) it will tell you how long since you setup the system.
I would suspect you would still want a UPS. I don't think house "power" setups have the switch over speed even if they're automatic. Most home generator setups are manual not sure about battery setups.
I got obsessed with uptime in the early 2000s, but for my desktop Slackware box. It ran a bunch of servers and services and crap but only for me, not heavy loads of public users. Anyway, I reached 6 years of uptime without a UPS and was aiming for 7 when a power outage got me.
Skill issue. Next time you can open up the computers power supply while it’s running, splice in a second power cable, and attach a UPS without powering down or getting electrocuted.
For legal reasons, /s
Not sure what your signature is supposed to do here but now I have 3rd degree burns and a fireball has engulfed my office wall
But more importantly, did your uptime get reset?
~~man~~ what's uptime?
Not much, time. What's up with you?
“Uptime” — aka the anxiety meter for every sysadmin.
Can I ask, what is the advantage of a Debian server over a True Nas one? Asking because I set up True Nas and wondering if I should switch it to Debian
True nas is nas software that moonlights as a server. Debian is a linux distro commonly used as the operating system for servers due to its incredible stability and reliability among other things. So reliable infact that it's used as the operating system for true nas scale! So unless your using the core version (that runs bsd) then your already using it. As far as rawdogging Debian on your hardware goes, id recommend against it unless you're looking to seriously up your admin game. No web interfaces, lots of time in the terminal ( command line ) and more configuration files than is anyway reasonable. And we haven't even started on virtual machines like proxmox ( also Debian based! ) or container critters like docker and kubernetes. (Iirc true nas uses kubernetes under the hood)

___alt-text: The "I lied, I don't have netflix" meme template. The girl with heavy dark rings around her eyes points a gun at the observer, with various images inserted in the background. The images include references to debian, libreboot, rsync, sed&awk, cron. The text reads: "I lied, I don’t have netflix - Take off your shoes, we’re going to learn to setup a NAS with Debian customized and automated to the bone and also automate the deployment process with Kubernetes. Everything will have 3-2-1 backups and controls will be networked to the volume slider in the radio of your car. We will use the motherboard of your calculator because it’s supported by libreboot."
Debian is well known for maintaining established packages in its repos. This means that all of the software is thoroughly tested, and therefore (usually) stable; however, the software in question is generally older, so it also means that sometimes you'll have to find your own approach if you want to run any newer services.
Configurability? I mean Truenas Scale is also based on Debian, but it's an appliance software, if you want NAS it's purpose made for that. You need to configure Debian yourself if you want functioning NAS.
I still remember when TN doesn't have native Tailscale apps/docker yet and everytime there's a Truenas update I need to reinstall and set up Tailscale from scratch.
If you just need a NAS with basic apps/docker, there is no reason to just use Truenas.
I use both, but run a Technitium DNS and Frigate on bare Debian.
At some point when I am less busy again I think I am gonna swap back to a debian based system because my experience on arch and red hat systems just hasnt been as good (this may be because I started on Debian based systems and keep trying to use commands that dont work on the other ones out of muscle memory)
I get bored every so often and move all the important stuff to an external drive or a separate internal one and completely change my os
I am on manjaro but I have also run arch, red hat, void, mint, Debian, Ubuntu and a bunch of others that I either put on laptops or something similar as messing around with devices
Tails and slitaz have to be my favorite to run from a USB but peppermint isn't the worst
I like having a consistent update and reboot schedule. Uptime feels overrated over stability and clearing the RAM occasionally.
I definitely have some Docker containers that randomly stop working, and they are more often consistently fixed by a reboot of the machine rather than a reboot of the container or the Docker service.
Not to mention the security implications of not rebooting after certain updates.
Huh. Only 11 days on the Raspberry Pi I'm using as a "desktop system" right now. (Arch Linux Arm, btw... though Arch Linux Arm sucks now-a-days.)
Let's check my RPi-based NAS:
[tootsweet@mynasserver ~]$ uptime
19:56:07 up 212 days, 18:43, 4 users, load average: 0.16, 0.04, 0.01
Also not as long as I'd have guessed.
My RPi uptime on one project will never exceed 4 hours.
I've got a cron job set to reboot my Raspberry Pi every 4 hours because I wrote a crappy Python app that continuously creates objects during operation that I would have to recreate, but I can't delete the originals, or rather, I can delete the original parent but the child survives and keeps its memory allocation. So a full reboot with autolaunch of the application on boot is my ugly janky workaround. Its a cosmetic application, nothing critical. Its just a colorful display of data metrics.
I can hear the horror and gnashing of teeth of real developers as they read this.
As a real developer...
I just remember that airplanes have "reboot the plane every 51 days" to prevent an overflow from crashing the plane in their maintenance manuals
So, like, yours can be improved, but it's not safety critical like other reboot requirements...
You just lack imagination. Some hikvision security cameras (the large, very expensive enterprisey ones) restart every couple of days due to "buildup of cosmic radiation".
No matter how competent you are as a developer, there is no escaping cosmic radiation! 😉
Oh shit! Forget all that stuff I admitted to. My RPi reboots every 4 hours because ... uh ... cosmic radiation.
Does NixOS apply kernel updates live? I can't recall from when I used it.
step 1: sudo apt install sl
step 2: fuck up
step 3: ???
step 4: profit!!!!
