[SOLVED] Notification about full disk

[evaldas]

Hello,

recently on each boot o box of Baobab 1.6.1 pops up with notification that I run out of disk space. It aso says that overall capacity of file system is 310 Gb, used 92,8 Gb and free is 217,8 Gb

Recently I tried to update my system and failed because of lack of space:

Code: Select all

There was a problem during the installation:

installing package dbus-1.6.18-1.3.mga4.x86_64 needs 1024KB on the / filesystem

installing package lib64dbus1_3-1.6.18-1.3.mga4.x86_64 needs 384KB on the / filesystem

installing package mariadb-common-core-5.5.38-1.mga4.x86_64 needs 444KB on the / filesystem

installing package mariadb-core-5.5.38-1.mga4.x86_64 needs 13MB on the / filesystem

installing package dbus-x11-1.6.18-1.3.mga4.x86_64 needs 276KB on the / filesystem

installing package lib64purple0-2.10.9-1.1.mga4.x86_64 needs 2MB on the / filesystem

installing package lib64mariadb18-5.5.38-1.mga4.x86_64 needs 4MB on the / filesystem

installing package rootcerts-java-1:20140703.00-1.mga4.x86_64 needs 564KB on the / filesystem

are there miscalculations of free space or what can I do?

What does

Code: Select all

df

entered in a terminal report is the free space on the / partition?

It might be best if you paste here the output of the df command.

thank you for your replay. the output of df comand was

See, that is your problem. You can find the biggest folders easily via e.g.

Code: Select all

du -mx / | sort -rn | head -20

to see the 20 biggest folders.

Thank you, I see, but what should I do? should I increase this part (then how) or should I delete files (then which)?

[jkerr82508]

It's impossible to advise you until we know which directories are the largest. What did you get when you ran the command that doktor5000 suggested?

Your basic problem is that your root filesystem partition is just not big enough. 12GB is not enough for a modern desktop Linux distro, particularly if you are running KDE and many of the toys that come with it. My own / has 13GB in use, and that is with a number of directories symlinked onto other drives.

You need to enlarge / (my own is 39GB but probably 20 would be enough for you).

This will inevitably involve destroying /home, so you will need to back /home up to some other drive before rearranging partitions. You can then move the contents of /home back onto the /home partition after it has been resized smaller.

Hi

gparted is a very useful partition editor if you are thinking about jiml8's suggestion.
You need to run it from either disc or usb device as you cannot easily resize your root [ / ] partition from within an in-use system.

1st rule is, of course, to back-up your home data just in case something goes wrong.

I found getting rid of some of the older kernels freed up space (the same thing happened to me!) . Every time a new one is released now I allways remove the oldest one at the same time.

[doktor5000]

Kernel packages are usually around 50MB, that's not that much for a > 10GB partition and not worth the hassle for the freed space alone.
It's more useful to find out what uses most of the space and kill the real spaceeaters first. It's also a good idea to look for the biggest packages installed, and remove if not needed anymore.

Code: Select all

rpm -qa --qf "%{SIZE}\t%{N}\n" | sort -rn | head -15

wht is gutenprint-foomatic, jre and libmateweather? maybe I don't need these? how to remove?

[doktor5000]

You haven't yet posted which directories are using the most space. So first things first:

You can find the biggest folders easily via e.g.

Code: Select all

du -mx / | sort -rn | head -20

to see the 20 biggest folders.

More then 4GB of cups logs. You have installed updates for Mageia 4, right? That should be fixed by those.
Check viewtopic.php?f=24&t=6926 and https://wiki.mageia.org/en/Mageia_4_Err ... pt_filters and https://wiki.mageia.org/en/Mageia_4_Err ... ig-printer

You can simply delete those logs. As root

Code: Select all

rm -f /var/log/cups/*

[jiml8]

/var/log/journal is out of hand too.

I would be looking at those cups logs (at least one of 'em) before deleting them; probably there is a misconfiguration that is causing the problem and you would want to fix the source of the problem.

[evaldas]

Thank you for help! I have choosed option to delete logs because it looked more simple to me and anyway I can't connect to my HP printer
Now I was able to install newest updates!
