Try 60GB of system logs after 15 minutes of use. My old laptop’s wifi card worked just fine, but spammed the error log with some corrected error. Adding pci=noaer to grub config fixed it.
I had an issue on my PC (assuming faulty graphics driver or bug after waking from sleep) that caused my syslog file to reach 500GiB. Yes, 500GiB.
Nearly 700gb in logs
wtf 🤯
Yeah I was confused as to where all of my storage went xD
*cough*80 GiB*cough*
11.6 mega bites
Ah, yes, the standard burger size.
You just need a bigger drive. Don’t delete anything
Oh lord watch me hoard
Once I had a mission critical service crash because the disk got full, turns out there was a typo on the logrotate config and as a result the logs were not being cleaned up at all.
edit: I should add that I used the commands shared in this post to free up space and bring the service back up
Fucking blows my mind that journald broke what is essentially the default behavior of every distro’s use of logrotate and no one bats an eye.
I’m not sure if you’re joking or not, but the behavior of journald is fairly dynamic and can be configured to an obnoxious degree, including compression and sealing.
By default, the size limit is 4GB:
SystemMaxUse= and RuntimeMaxUse= control how much disk space the journal may use up at most. SystemKeepFree= and RuntimeKeepFree= control how much disk space systemd-journald shall leave free for other uses. systemd-journald will respect both limits and use the smaller of the two values.
The first pair defaults to 10% and the second to 15% of the size of the respective file system, but each value is capped to 4G.
If anything I tend to have the opposite problem: whoops I forgot to set up logrotate for this log file I set up 6 months ago and now my disk is completely full. Never happens for stuff that goes to journald.
It can be, but the defaults are freaking stupid and often do not work.
Aren’t the defaults set by your distro?
AAfaict Debian uses the upstream defaults.
Still boggles my mind that systemd being terrible is still a debate. Like of all things, wouldn’t text logs make sense?
Wait… it doesn’t store them in plaintext?
Nope, you need journalctl to read.
That’s asinine.
Yeah, and you need systemd to read the binary logs. Though I think there may be a setting to change to text logs, I am not sure because I avoid systemd when I can
Wouldn’t compressed logs make even more sense (they way they’re now)?
This once happened to me on my pi-hole. It’s an old netbook with 250 GB HDD. Pi-hole stopped working and I checked the netbook. There was a 242 GB log file. :)
Systems/Journald keeps 4GB of logs stored by default.
Title gore
Recently had the jellyfin log directory take up 200GB, checked the forums and saw someone with the same problem but 1TB instead.

logrotate is a thing.
I recently discovered the company I work for, has an S3 bucket with network flow logs of several TB. It contains all network activity if the past 8 years.
Not because we needed it. No, the lifecycle policy wasn’t configured correctly.
Windows isn’t great by any means but I do like the way they have the Event Viewer layout sorted to my tastes.
True that. Sure, I need to keep my non-professional home sysadmin skills sharp and enjoy getting good at these things, but I wouldn’t mind a better GUI journal reader / configurator thing. KDE has a halfway decent log viewer.
It might also go a long way towards helping the less sysadmin-for-fun-inclined types troubleshoot.
Maybe there is one and I just haven’t checked. XD
I couldn’t tell for a solid minute if the title was telling me to clear the journal or not
Eh, I just set $ROOTFS to ro and my $HOME to rw.
