[SOLVED] How to free space

[pmithrandir]

Hello,

I have installed my mageia years ago.

Over time, my 19 GB for / are getting too small.

But, I have no idea on how to remove stuff.
I checked and /usr takes about 13GB, and out of that /usr/lib and /usr/lib64 are taking 4GB each.

The pthers folder such as /var are reasonnable, under 1GB.

If I use the package manager, I will be able to remove top level application (I don't have much) but not really the low level libraries.

What would be your advice ?

Best regards
Pierre

PS : if it's not too hard, I might be able to "get" few GB from my next partition, /home.

Hi

Have you read https://wiki.mageia.org/en/Removing_packages ?

Also, DNF repo sync function hav been handy for me

For a short-term fix, remove some bigger packages which you do not need. To list the 150 biggest packages:

Code: Select all

rpm -qa --queryformat '%{SIZE} %{NAME} \n' | sort -rn | head -150

Also check packages which are not available from installed repositories, if that is an upgraded installation

Code: Select all

urpmq --not-available

If you don't know about some packages, then either ask or post the output here.
Also output as root from

Code: Select all

du -mx / | sort -rn | head -50

might be helpful.

For a long-term fix, reinstall and next time use LVM instead of classical partitioning as you can dynamically increase the size and don't need to mangle partition tables.
Also nowadays you should not go below 50GB for / IMHO.

Nice one, I added it now to wiki at my first link in post above.

I second the suggestion to use LVM.
Our diskdrake support online expansion of partitions. Never failed for me.
I almost always make a small /boot then a large LUKS encrypted pv for LVM, so everything except /boot is encrypted with one key.
All done in installer/diskdrake.

Thank you all.

By listing the biggest package I found a few one that were not so needed.

Also, my computer have been upgraded for a long time, or reinstalled, but always keeping the /home.

I'll flush the disk and move to LVM when I'll be back with a fiber connexion.

Thanks for your advices.

Good

Also, my computer have been upgraded for a long time

Have you checked you do not have any old packages, i.e .mga7, .mga8 that is not used anymore?

Another trick i used on my old Thinkpad T43
(it have a 40GB disk where most is used for windows XP, so...)
I uninstalled the 1,1GB kernel-firmware-nonfree, and did not see any regressions.
