- Demiurge 5y agoI worked with multiple ops/infra teams, and have seen standard server rooms and advanced server rooms. They’re not supposed to have pipes leaking on the racks, that’s ridiculous. I know many stable redhat servers that didn’t need to reboot for years. I also maintain websites on hetzner servers that haven’t needed to reboot in years, under pretty high load. On the other hand, I got a hostnoc dedicated server and that thing went offline three times a month. So yeah, you have to know what you’re doing regardless of whether you’re building a server room or a k8s cluster.

- bob1029 5y agoSo, we do ~daily restarts on our customers' systems. We have a solid 12 hours per day to patch up a server before it needs to be in production again. That said. We communicate directly with other systems on the same premises that probably haven't been rebooted in over a decade. Building something that can run 10 years without downtime is not happenstance. It is very intentional and deliberate engineering.
- fxtentacle 5y agohttps://en.wikipedia.org/wiki/Kpatch https://en.wikipedia.org/wiki/Kpatch Allows you to patch the kernel without reboot.
- Demiurge 5y agoAs mentioned above, they were, both RedHat and Ubuntu now support kernel updates without restart.
