logrotate: log2ram permission problem - dheijl - 04-11-2025

On one of my Moode players, both 9.3 (upgraded), I noticed this in journalctl:

Apr 11 00:00:00 marantz logrotate[70736]: error: Ignoring log2ram because the file owner is wrong (should be root or user with uid 0).

log2ram eventually fills up on this player, that's why I checked.

My other player properly cleans out log2ram every day.

Is there an easy way to fix or should I just reinstall?

Thanks

What was the journalctl command that you used?

RE: logrotate: log2ram permission problem - Tim Curtis - 04-11-2025

Nvm.

This is prolly the cause of the logrotate error.

Code:
pi@moode9scn:~ $ ls -l /etc/logrotate.d/

total 52

-rw-r--r-- 1 root root 120 Feb 14  2023 alternatives

-rw-r--r-- 1 root root 173 May 25  2023 apt

-rw-r--r-- 1 root root 130 Oct 14  2019 btmp

-rw-r--r-- 1 root root 112 Feb 14  2023 dpkg

-rw-r--r-- 1 pi   pi    97 Sep 18  2024 log2ram

-rw-r--r-- 1 root root 215 Nov 25 12:21 php8.2-fpm

I'll investigate why the user:group is pi:pi instead of root:root and fix it but that log rotate error shouldn't have anything to do with the log2ram service.

Erm. We find in /etc/logrotate.d the file log2ram so, yes, the logrotate service will touch the log2ram log. Now that I know to look, I see the OP's error in the journals of the two players currently powered up here.

Incidentally, there seem to be some other, unrelated errors in that directory.

Cases in point,

- file /etc/logrotate.d/mpd refers to files /var/log/mpd/*.log which won't pick up the actual mpd log file /var/log/mpd/log.

- file ppp refers to file /var/log/ppp- connect-errors. Should these be "php" or are we really referring to the old point to point protocol used with dial-up modems?

I haven't looked carefully at logrotate to see where permissions matter.

Kent

I noticed that /var/log/journal was filling up with logfiles, that's why I ran "journalctl" and noticed that line.

I attach the journalctl output.

lol, indeed thats the old ppp connection protocol

Here are the fixes

Code:
sudo chown root:root /etc/logrotate.d/log2ram

sudo sed -i 's/*.log/log/' /etc/logrotate.d/mpd

Applied, thanks!
