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 👍

Almost the same here. Well, du -shc *|sort -hr

I admin around three hundred linux servers and this is one of my most common tasks - although I use -shc as I like the total too, and don't bother with less as it's only the biggest files and dirs that I'm interested in and they show up last, so no need to scrollback.

When managing a lot of servers, the storage requirements when installing extra software is never trivial. (Although our storage does do very clever compression and it might recognise the duplication of the file even across many vm filesystems, I'm never quite sure that works as advertised on small files)

We'd use du -xh --max-depth=1|sort -hr

Interesting. Do you often deal with dirs on different filesystems?

[–] pete_the_cat 1 points 1 year ago (1 children)

Yeah, I was a Linux System Admin/Engineering for MLB/Disney+ for 5 years. When I was an admin, one of our tasks was clearing out filled filesystems on hosts that alerted.

Sounds pretty similar to what I do now - but never needed the -x. Guess that might be quicker when you're nested somewhere there is a bunch of nfs/smb stuff mounted in.

We'd do it from root (/) and drill down from there, it was usually /var/lib or /var/logs that was filling up, but occasionally someone would upload a 4.5 GB file to their home folder which has a quota of 5 GB.

Using ncdu would have been the best way, but that would require it being installed on about 7 thousand machines.

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

[–] [email protected] 2 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!
