I clicked to update the home assistant core this morning and it says out of space.
I have HA OS on 32gb, how can it be ?
after going into terminal, and see the list and it shows a lot of overlay2 folders taking space.
what do i do now ?
Thats part of docker for storing its containers. So this is the cli for your docker and not HAOS itself. Are you running core?
What does docker system df say?
I am running HA os on a proxmox vm which is 32GB
I did login from the HA console and ran the df -h command to see the first image.
since i posted i have been trying to prune docker, journal and everything. nothing seem work.
I also had some problems with haos and proxmox and running out of space.
My main problem where the local backups, both from HAOS and Proxmox.
Now i create most of my HA backups on a net share and also have an eye on the proxmox snapshots.
where is the location of HA backups in HA OS? I can check if it took space
under options / system / backups. i dont know where to see the total space used but if you see 10 loacl backups with 2gig each … 
I did a search for backup folder with size, the highest i found is 15MB
find / -type d -name "backup" -exec du -sh {} + | awk '$1 ~ /[0-9]+M/ && $1+0 > 500 || $1 ~ /[0-9]+G/' | sort -h
Are you using MariaDB, InfluxDB or only the default SQLite?
You could check the homeassistant container:
docker exec -it homeassistant du -sh /*
try:
du -hd 1 /mnt/data/supervisor | sort -hr
do you have proxmox snapshots, which are eating up your disk space?
and check the supervisor container, esp. the data directory:
docker exec -it hassio_supervisor du -sh /data
here is the top 3 high size:
I don’t have snapshots, but checked my full backup of ha vm, its consistently at 34.36 GB since 2 Nov 2024
19.9 G. /data
can i clear this backup ?
I have proxmox backup everyday and i could restore easily if needed.
I went the HA ui and delete all the backups except the last core backup
used space came from 98% to 46%
Is this normal ? meaning ha about 15gb
Depends on the size of you DB, which is related to the history size you are keeping (default is 10 days) and on the number of entities you have and their update intervall.
Details: see here
You have upgraded til 2025.01?
The new backup scheme was consuming all my hdd space…
