if the 'snapper list' output is complete (sudo missing?) then your problem is not that you have snapshots enabled. something has gone wrong and you have a bunch of old (=huge) orphaned snapshots. (if i have the correct instruction from bash history -> check) these can be removed with e.g. sudo btrfs sub delete /.snapshots/6/snapshot

That's it! I removed all orphaned snapshots, and got back space on /. (But I still wonder why the space limit was not observed) Thanks! Albert

Quota information is corrupted. You cannot have 179GB exclusive data on 40G disk. This is the likely reason why cleanup stopped working. Check /var/log/snapper.log for any errors. Try running "btrfs quota rescan" and check whether values are more sensible after that. -- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse+owner@opensuse.org

Hi all,

I want to get rid of snapshots, because they filled my / volume. I ran snapper delete, and limited the number of snapshots to 1, and disabled snapper in yast2 config. I got only very little space back. If I understood well what I read to physically remove files from /.snaphots, I would need to run suse.de-snapper and btrfs-balance found in /etc/cron.daily and cron.weekly directories. But I do not have any of them. Where are they? I use Tumbleweed with KDE.

Thanks, Albert

if you actually disabled snapshots, there should be non. aiui, the space utilized by the snapshots will not show a change until the filesystem is renewed, this may be wrong. have you rebooted

never heard of suse.de-snapper

did you look at /.snapper to see if the snapshots were removed?

grep -r btrfs /etc/cron.*/* reveals no files with btrfs in their names on my systems

ps: snapshots are a good thing. saved me twice when updates were interrupted. how many snapshots did you have? did you limit the remaining space available for snapshots? how much space did you allocate to the root file system? limiting snapshots to "1" is counter-productive, imnsho.

ps1: https://en.opensuse.org/openSUSE:Mailing_list_netiquette#Signatures

ps2: I assume you are utilizing Tumbleweed. conversation re: Tumbleweed is generally on opensuse-factory list.

The grep command above returns with none.  Earlier I allowed two snapshots and it worked fine (and I agree, it's a good thing), but the space got filled up lately. Unfortunately I did not set space limit. In /.snapshots there are seven directories which I think belong to older snapshots and a config file. As to suse.de-snapper, see e.g. this https://forums.opensuse.org/showthread.php/521290-snapshots-are-filling-root... Regards, Albert
