From the ‘btrfs’ manpage: ```auto The resize command does not manipulate the size of underlying partition. If you wish to enlarge/reduce a filesystem, you must make sure you can expand the partition before enlarging the filesystem and shrink the partition after reducing the size of the filesystem. This can done using fdisk(8) or parted(8) to delete the existing partition and recreate it with the new desired size. When recreating the partition make sure to use the same starting disk cylinder as before. ``` Is it safe to assume you have free space in your partition into which your filesystem can grow? – Good luck.

If space, then first off configure the snapper config, second run the maintenance cron job. – Cheers Malcolm °¿° LFCS, SUSE Knowledge Partner (Linux Counter #276890) SUSE Linux Enterprise Desktop 12 SP1|GNOME 3.10.4|3.12.51-60.25-default If you find this post helpful and are logged into the web interface, please show your appreciation and click on the star below… Thanks! ---

Then once configured for your requirements, manually run the daily cron job to clean up the snappshots; ```auto /etc/cron.daily/suse.de-snapper snapper list|awk 'NR > 3 { print }'|wc -l ``` The amount of snapshots should have decreased? Now you need to clean up the btrfs filesystem; ```auto /usr/share/btrfsmaintenance/btrfs-balance.sh btrfs fi usage / ``` If the btrfs balance command isn’t found, then install and run the above commands; ```auto zypper in btrfsmaintenance btrfs fi usage / ``` This should clean up and recover lost space. It should also have added a weekly cronjob to balance? ```auto ls -la /etc/cron.weekly/btrfs-balance.sh lrwxrwxrwx 1 root root 44 Feb 28 22:54 /etc/cron.weekly/btrfs-balance.sh -> /usr/share/btrfsmaintenance/btrfs-balance.sh ``` If not, create a softlink so it runs weekly. – Cheers Malcolm °¿° LFCS, SUSE Knowledge Partner (Linux Counter #276890) SUSE Linux Enterprise Desktop 12 SP1|GNOME 3.10.4|3.12.53-60.30-default If you find this post helpful and are logged into the web interface, please show your appreciation and click on the star below… Thanks!
