#264207 — systemd-journald log location

Hi all,

Is it a good idea to move it from /run/log/journal to e.g. /var/journal-log?

I can't find a suitable option in /etc/systemd/journald.conf

I recently increased SystemMaxUse and RuntimeMaxUse which quickly filled 
up all space.

I didn't realise that our cloud provider decided to image the VM with 
only 100 MB space assigned to /run !

Not easily changeable. Debian 10.13.

Regards,
Adam

If you want to enable persistent journal storage (which by the way
has become the default in more recent Debian releases), please follow
the two steps documented in "man systemd-journald":

    mkdir -p /var/log/journal
    systemd-tmpfiles --create --prefix /var/log/journal

Or... check whether this already exists and contains data on your
system.

On my Debian machines, /run/log/journal is empty, and everything
goes into /var/log/journal. I haven't changed the location.

See the journald.conf(5) man page. :-)

This may be because I use Storage=persistent.
