/var/log/journal is very large

[jimlongo]

Ran out of disk space doing a backup.
Unusual.

First thing I find is that /var/log/journal has grown to 3.2GB. (also 3.8G ./apache2)

Checked WHM and rotation size is 300MB. Also notice that "journal" is not available as a choice in the Log Rotation Configuration.

I can manually delete the files of course, but figure there must be an underlying reason why.

Hey there! There is a SystemMaxUse parameter inside /etc/systemd/journald.conf - can you adjust that value? By default, on the systems I checked just now, it is blank.

Some more details on this configuration here:

How to rotate systemd-journald log in CentOS/RHEL 7

Question: How to rotate systemd-journald log under /var/log/journal/*/ or /run/log/journal/*/? journald logs can be rotated using the /etc/systemd/journald.conf configuration file. By default all the options in the configuration file will be hashed out and at their default values.

Thanks. I was able to set it to

SystemMaxUse=400MB

Haven't seen the effect yet. Can I kick that cron (not sure which one is responsible)?

That's a great link from @quietFinn that talks more about how the journal gets handled.

Thanks, that did help … just to note —rotate didn't work on my system, but vacuum did.
