#92I remember a discussion here about a dude who did this with memory in game development. People didn't like the idea very much.
To me it has a taste of domain squatting or GPU scalping, but you don't do it with strangers, but your team.

#94All my servers have an alarm when disk space goes above 70%. It sends an email every hour once the disk usage goes above 70%. Never had a server go down because of disk space issue after adopting this practise. Also one of the main reasons server disks go full is generally log files. Always remember to "logrotate" your log files and you will not have this issue that much. Yes one more thing, for all user uploaded fil…
Is there a package I can install to set this up?

#95Ah, the classic 'speed-up loop' approach: https://thedailywtf.com/articles/The-Speedup-Loop About the blogpost itself: The disk filled up, and that's one thing you don't want on a Linux server—or a Mac for that matter. When the disk is full nothing good happens. I had this happen few times on a Mac and every time I was shocked that if disk gets full you cannot even delete a file and the only option is to do a full sy…
MacOS has given the user nagging "startup disk is almost full " prompts for as long as I can remember, yours doesn't?

Icinga is a common solution for monitoring FS and other use metrics. I imagine his setup, if custom rolled, is a shell script checking df and sending an email when the usage is at or above 70

#99How is this better than sounding alarms when free disk space drops below 8GB? If you’re going to ignore the alarms, then you’re going to have the same problem after you remove your spacer file and the disk fills up again!

#100No. Careful partitioning is the solution to this problem. Monitor the growth of your partitions and make sure nothing on rootfs or other sensitive partitions grow significantly.
I don't think this has to be an either/or scenario. Having some bloat you can get rid of quickly is a nice backup in case your monitoring fails for whatever reason.
