---------------------------------------- limited resources March 30th, 2021 ---------------------------------------- Tonight I set up resource limits on cosmic. Specifically I set up CPU and Memory limits for users. I don't get a lot of bad eggs amongst the voyagers, but it's easy to take a bigger slice of the pie than you intend on a tiny tilde. Someone had a newsreader running tonight that was accidentally using the entire 1024MB I have to offer. I wasn't sure how to set this up, so I did a little research and for once systemd came to the rescue. Here's what I did: ---- mkdir -p /etc/systemd/system/user-.slice.d cat > /etc/systemd/system/user-.slice.d/50-memory.conf << EOF [Slice] MemoryMax=80M CPUQuota=8% EOF sudo vim /etc/systemd/system.conf # uncomment and set the following values in that file: DefaultCPUAccounting=yes DefaultMemoryAccounting=yes systemctl daemon-reload ---- And that's it! I may tweak those quota values over time to make sure the system stays healthy but people can still use it. So far so good.
