From Wikipedia, the free encyclopedia

Linux is a family of open source Unix-like operating systems based on the Linux kernel, an operating system kernel first released on September 17, 1991 by Linus Torvalds. Linux is typically packaged in a Linux distribution (or distro for short).

Distributions include the Linux kernel and supporting system software and libraries, many of which are provided by the GNU Project. Many Linux distributions use the word "Linux" in their name, but the Free Software Foundation uses the name GNU/Linux to emphasize the importance of GNU software, causing some controversy.

Thanks to dust I deleted a 70 gig file on my drive (lm.paradisus.day)

Dust is a rewrite of du (in rust obviously) that visualizes your directory tree and what percentage each file takes up. But it only prints as many files fit in your terminal height, so you see only the largest files. It's been a better experience that du, which isn't always easy to navigate to find big files (or atleast I'm not good at it.)

Anyway, found a log file at .local/state/nvim/log that was 70gb. I deleted it. Hope it doesn't bite me. Been pushing around 95% of disk space for a while so this was a huge win 👍

I admin around three hundred linux servers

What do you use for management? Ansible? Puppet? Chef? Something else entirely?

[–] [email protected] 3 points 1 year ago (1 children)

Main tool is Uyuni, but we use Ansible and AWX for building new vms, and adhoc ansible for some changes.

Interesting; I hadn't heard of Uyuni before. Thanks for the info!

Seems it just runs Salt/Saltstack?

Suse forked Redhat's Spacewalk just before it turned into Foreman + Katello.

Then worked an absolute crapload on it to turn it into a modern orchestrator. Part of that was to adopt salt as the agent interface, gradually getting rid of the creaking EL traditional client.

To say "it just runs salt" is to rather miss all the other stuff Uyuni does. Full repo and patch management, remote control, config management, builds, ansible playbook support, salt support, and just about everything else you need to manage hundreds of machines. Oh, and it does that for Rocky, RHEL, Alma, Suse, Ubuntu, Debian and probably a bunch more too, by now. Has a very rich webui, a full API and you can do a bunch more from the cli as well. And if your estate gets too big to manage with one machine, there are proxy agents, as many as you want. I only run a couple of hundred vms through it, but there are estates running thousands.

And it's free and foss.

Honestly, it's pretty awesome and I'm amazed it's not more widely known.

Oh that's pretty nifty, thanks for the comment. Sorry wasn't trying to minimize the tool, I was simply referring to the orchestration/config management aspect of it when I looked it up real quick.

I used to be responsible for configurations of 40,000 (yes forty thousand) VMs for a large company using puppet and then later using Ansible and that was an interesting challenge. I've been out of the configuration management game for a few years now though so I'm pretty out of the loop. Was familiar with spacewalk back in the day too.

I'll have to check Uyuni out, thanks for sharing!
