rpool no free space

[stefgrifon]

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.

Thanks for your reply.

Unfortunately it did not help me.

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?

Hello,

I am sending you all the screenshots

Thanks


find -type f -exec du -Sh {} + | sort -rh | head -n 20


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

I think you have found it, right?

Looks like your 411GB Backup file is the problem.

Yes, but how did this happen? I cannot understand how I made this mistake.

I have deleted all the backups from a GUI.

So will i use this command?

find /var/lib/pmg/backup -iname 'pmg-backup_*.tgz' -mtime +7 -delete

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.
