Hard Pass

Archive: [ https://archive.is/zarQO ]

I have noticed that my home server is strangely using lots of swap (~5 GB), despite having only a few lightweight processes running and loads of RAM installed (32 GB).

Upon configuring Grafana + Prometheus, I noticed a trend where cache + buffer will progressively increase until swap starts to be used. My system and services combined will use ~8 GB RAM. Upon rebooting, the cache + buffer will start anywhere from 3--10 GB, progressively ramp up to ~25 GB in 1--2h, where swap will start to be needed (~3 GB). See the image attached for reference.

My swap filesystem is on an expensive (to me) SSD, and I would like to reduce its wear by as much as possible. I understand that swap can introduce only minimal wear on SSDs depending on its nature and that it can be harmless, but I am still not sure what is causing this behavior (and why) and whether I should worry about it or not. So I figured I should investigate what is happening here.

My main question is, how can I figure out what is causing this behavior? Is it expected? I am looking for guidance from others who are more experienced than me in the topic.

A little bit about my system:

I am running Debian 12 on an NVMe SSD containing the root partition (btrfs) and docker services. I also have two HDDs, one with persistent data (ext4), and the other with backups (ext4). This is majoritarily a single-user machine. I tried using the following kernel parameters, but it hasn't helped:

vm.swappiness=10
vm.vfs_cache_pressure=200

My docker services are:

• *arr stack
• jellyfin
• nextcloud
• immich
• open-webui + ollama
• pi-hole
• invidious
• romm
• nginx proxy manager
• grafana + prometheus
• other minor services that I don't think are doing much (uptime-kuma, stirlingpdf, vaultwarden, etc)

Presumably I'd at least end up on a list from this post, or if I already am on there, they'd add an underline.
