August 1, 2025Aug 1 Good afternoon,I've done some searching on my own, but all I've found are hundreds of posts about people filling rootfs, how to stop that, whats doing it, ect, ect. What I'm curious about is if it's possible to increase the size of rootfs without adding additional ram? (insert download more ram joke?!)It appears, at least on my system, that during bootup it's using half of the 32GB of ram I have installed. (rootfs is 16GB) I guess my first question is, is that standard to use half of system ram? So if you have 8GB it'll use 4GB, 16GB would be 8GB and so on.This has been perfectly fine for years, and honestly may continue to be, but I am curious if there's a conf file we can edit to increase from 50%, or set a specific amount? I do use rootfs as a transcoding location for Plex so as not to wear down my cache drive. I've never had an issue with rootfs filling due to the transcoding, but as I allow more users to use it, it "might" become a concern. I run no VMs, only a handful of Docker images and plugins, so I could very safely increase that from 16GB to say 24, maybe a bit higher.Any info would be very much appreciated!Void4ever

It also defaults to 50%.You can resize either of them with mount -o remount,size=<whatever> <mountpoint> but 32G isn't really enough to go past the default 50%. 16GB tmpfs + whatever RAM the system and services use, and not exceeding 80% total RAM use doesn't leave much room.
