Hello,

i have installed the proxmox on 2 ssd zfs 500g.

This proxmox has only one vm machine.

Those are empty

Why does this happen?

Thank for your help,
Stefanos

Maybe its the Syslog? You can run journalctl --vacuum-time=1d to reduce it to 1 day of logs or journalctl --vacuum-size=1G to reduce the size to 1GiB. Before you remove too much, you might want to have a look with journalctl to find out why the log is so big. Does it keep many days, or did you have many (passthrough related) errors in a certain period? If vacuuming helps, you probably want to configure it to not use so much space in the future.

What is your output of zfs list -o space -r rpool and find -type f -exec du -Sh {} + | sort -rh | head -n 20 and du -Sh | sort -rh | head -20?

So missing discard or old snapshots aren`t a problem here.

I think the 2nd and 3rd commands only listed the biggest files/folders in your root users home directory because you executed them there. You could run this to see the 20 biggest files on your entire system: find / -type f -exec du -Sh {} + | sort -rh | head -n 20

Its a PVE backup of a VM where the VMID is 1000. If your backups are that big, maybe you should add a dedicated HDD for you backups or use a network share for it.
