snapper cleanup number

English Applications
#1

Hi,
I recently had a my / run out of space due to snapper snapshots. I then manually deleted a bunch to make space, but I know there is the

snapper cleanup

command. I tried running it with the cleanup algorithm and got the following output:

Venus:~ # snapper -v cleanup number
Deleting snapshot from root:
1
Deleting snapshot failed.

Here is my snapper config for root:

Venus:~ # snapper get-config
Key                    | Value
-----------------------+------
ALLOW_GROUPS           |

More information:

Venus:~ # snapper --version
snapper 0.5.1
flags btrfs,lvm,no-ext4,xattrs,rollback,btrfs-quota,no-selinux

As far as I understand it, snapshots 0 and 1 can’t be removed and that is why it fails. But why does it try to delete snapshot number 1? Shouldn’t that be excluded from the cleanup? I did use “snapper rollback” before on this installation, maybe that has something to do with it?

Hi
Yes, AFAIK the rollback is the new starting point. Consider modifying you /etc/snapper/configs/root to reduce snapshots (I only keep max 4) then use the cron job manually to clean up snapshots and then run the btrfs balance cron job as well to clean up space.


/etc/cron.daily/suse.de-snapper
/etc/cron.weekly/btrfs-balance

Also check the status of the btrfs-balance service;


systemctl status btrfsmaintenance-refresh.service

Thank you, I will try that as soon as I am back home.
