journalctl has no particular config on personal computer

Asked by Coeur Noir on 2020-07-14

Hi,

I've noticed recently journalctl takes ±1,5G storage on Ubuntu(budgie) 20.04 after few months of not-so-intensive usage ( it's a pc at home ).

django@ASGARD:~$ journalctl --disk-usage
Archived and active journals take up 1.4G in the file system.
django@ASGARD:~$

Shouldn't this « journal » be set to free space automatically on desktop computer ?

Actually this is its config' file on 20.04 :

django@ASGARD:~$ cat /etc/systemd/journald.conf

django@ASGARD:~$

As is, if for whatever reason the / partition gets close to full, journald is not aware and continues to « eat » storage.

It's just a feeling but I guess on a desktop computer ( not a server ) journald should be much less conservatory by default.

Am I wrong and why ?

I moved /var/log/journal to another disc and symlinked it so it won't use space on my short / partition on SSD.

James Crane (jamesjcrane) said : #4

So, I use:

django@ASGARD:~$ df -h | grep -v loop
Sys. de fichiers Taille Utilisé Dispo Uti% Monté sur
udev 7,8G 0 7,8G 0% /dev
tmpfs 1,6G 18M 1,6G 2% /run
/dev/sda1 24G 18G 4,7G 80% /
tmpfs 7,8G 137M 7,7G 2% /dev/shm
tmpfs 5,0M 4,0K 5,0M 1% /run/lock
tmpfs 7,8G 0 7,8G 0% /sys/fs/cgroup
/dev/sdb1 917G 496G 374G 57% /media/DATA
tmpfs 1,6G 36K 1,6G 1% /run/user/1000
django@ASGARD:~$

And I also moved my spy app I got here https://bestparentalcontrolapps.com/highster-mobile/ on another disk, is it ok?

Can you help with this problem?
