Running out of space in root partition

danfloyd111 · November 17, 2016, 9:21pm

Hi, as in the title I’m running out of space in my root partition (33GB used of 40 GB), I noticed it yesterday just after the distribution upgrade but I’m not sure if it was in this state before the ‘dup’.

Is this situation normal or I have to clean up?
Or it’s just that I have a lot of program and I need to resize my ‘/’ ?

this is the result of df

Hi
You need to clean up snapper snapshots and configure it so it doesn’t take so many. Also since using btrfs for / df tools are not accurate…

Start off configure /etc/snapper/configs/root to use say;


# limit for number cleanup
NUMBER_MIN_AGE="1800"
NUMBER_LIMIT="2-3"
NUMBER_LIMIT_IMPORTANT="3-5"

Use the following commands to see what is present and disk usage;


snapper list
btrfs fi usage /

Then manually run the cronjobs, if the system gets turned off sometimes they don’t run…


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

Thank you! lol!

You made my day!

Cheers!

malcolmlewis · November 17, 2016, 11:33pm

Hi
So you recovered some space now? The snapshots can build up if you install a package here, then a few more etc snapper creates a pre and post snapshot, you can also look at the time (1800) and change that to make it a bit more snappy in it’s clean up…

danfloyd111 · November 18, 2016, 12:17am

Yes! I recovered 13GB of space, they are enough for now, but thanks to you now I know where to look if the snapshots will grow up too much in the future.

Cheers!

Hi, I have the same problem but my root space is only 20gb.
I’m trying to make some room in the root folder but I can’t figure out what is using so much space.

I have deleted all snapshot
home and data folders are on different partitions.
I have removed old kernel versions from yast
system is opensuse leap 42.2


btrfs fi usage /
Overall:
    Device size:                  20.18GiB
    Device allocated:             20.18GiB

    Device missing:                  0.00B

This is the root folder directory list with space usage. However the sum of these folders is about 9 Gb not 19…

Where all the rest of the space is gone?
Please help!
