But why doesn’t it ever empty the swap space? I’ve been using vm.swappiness=10 and I’ve tried vm.vfs_cache_pressure at 100 and 50. Checking ps I’m not seeing any services that would be idling in the background, so I’m not sure why the system thought it needed to put anything in swap. (And FWIW, I run two servers with identical services that I load balance to, but the other machine has barely used any swap space – which adds to my confusion about the differences).
Why would I want to reduce the amount of memory in the server? Isn’t all that cache memory being used to help things run smoother and reduce drive I/O?
Ah that’s handy to know the status can show more detail for individual interfaces! I still use /etc/network/interfaces to set up each port so systemd shows them all unmanaged. Maybe some day I’ll try switching to that kind of setup.
Where do you find default link files at? There’s nothing relevant under /usr/share/doc/systemd/. I had to do a lot of online reading to find an example of selecting them by the MAC address, and the
NamePolicy=
line was critical to making it actually work.I don’t suppose you happen to know of a way for systemd to manage a DSL connection (CenturyLink)? The old pppd setup seems to be getting hammered by systemd for some reason even though there’s no service file for it, but ppp0 refuses to try connecting on the new server until I can log in, stop it, and restart it again. It’s like it is trying to connect way too early in the boot and gets locked up.
