Persistent Logging

[RiSpa]

Hello,


On my RevPi, I want to enable persistent logging by systemd and journald.
Hardware: RevolutionPi Core SE
Image: 2023-09-26-revpi-bullseye-armhf

Attempt 1:
Change the appropriate configuration.

Code: Select all

Storage=persistent

in /etc/systemd/journald.conf

Code: Select all

systemctl restart systemd-journald

This creates /var/log/journal (for group 'root') but logs do not persist after reboot.

Code: Select all

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

This changes the group to 'systemd-journal' but logs do not persist after reboot.

Code: Select all

systemctl restart systemd-journald

Attempt 2:
Create persistent logging directory manually without changing configuration.

Code: Select all

mkdir -p /var/log/journal

Code: Select all

systemctl restart systemd-journald

This creates /var/log/journal for group 'root' but logs do not persist after reboot.

Code: Select all

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

Code: Select all

systemctl restart systemd-journald

This changes the group to 'systemd-journal' but logs do not persist after reboot.
Also, /var/log/journal is removed after reboot.

How do I succesfully make the systemd logs persistent across system reboots?


Kind regards,
rispa

Hello rispa, with the current bullseye I can work with

Code: Select all

journalctl

and see that the journal entries are retained for several days:

journalctl

So please check if your system is up-to-date. You can use the steps from here:
