Sudden unexplained low disk space
I started getting some errors with updating about not enough free space and i noticed that dolphin all of the sudden reports only 9gb of free space
the strange thing is i cant find what is using up all my space. my home directory is only 1tb and i have a 2tb disk. there's no way bazzite itslef could be using the remaining 1tb?

If you have btrfs snapshots, those will mess up available space as well I think.

file light not sowing anything unusal here

What games or things have you downloaded?
i have a lot of games thats why the 1tb in my home directory is not strange. but i wondering were the other half of my disk went
You had any other os on the directory before or set partition?
nope bazzite the only os on this disk i wiped the whole disk to install bazzite
Hmm ok strange and you check how much storage you set bazzite for partition storage and I will say very few games or application do keep taking storage for the many times you played the game without deleting the old shader files like never winter for example
yeah but shaders and games would be in the home directory and thats making up only half of my total disk space (1tb) no idea where the rest of the disk is going i used to bave about 200gb free
Hmm its gotta be some application running that is slowly taking your storage and there is no way it can be a screen recorder though because I don’t think overwolf is on bazzite
but even that would be on the home folder i think there should be no userdata outside the home folder
System flatpaks are under /var but not home I think
achtually good point it could be that
Try a run on say /var/lib

hmm only 30 gb in
/var/lib/
using ncdu as it makes it really easy to exclude folder
Then snapshot
Or depending on your podman usage patterns, possibly stray builds/images/containers
:mrpgSighFacePalm: it was snapshots i didn't relize how bad of an idea weekly snapshots of my home directory was
where did you find them?
in btrfs assitent they do show in tools like filelight or ncdu beacuse there a btrfs thing
so thats why there was unacounted for used space
tbh I have never used thoses before
btrfs snapshots arent supposed to use that much space but prob because my home was 1tb it was using about 200gb thruout 4 snapshots
seem somewhat easy to look through but where did you find the snapshots?
if you never configured them they shouldnt be a problem but you can see then in the
btrfs-assistent
tool thats presinstalled on bazziteit would show any snapshots here

ah ok I was curious
yeah when going through the just commands in the terminal i saw snapshots and i was like " hmm that could be a good way of keeping a history of my configs" and enabled it. the problem is it was snapshoting more than just configs its the whole home folder by default
oh so its like a restore point basically?
yup its one of the benifts of btrfs it has build in snapshoting capablities aka restore points but like instanous
