Install a P9 Open Power Hardware with the latest OP920 Firmware images provided in the following link:

Then check if the OPAL prd generated logs are captured in /var/log/opal-prd.log file.

root@ltc-wspoon11:/var/log# cat opal-prd.log
root@ltc-wspoon11:/var/log# echo $?
0

Notice that opal-prd.log file is owned by root user while opal-prd.log.1 is owned by syslog.
That means someone has manually created that log file?

I deleted opal-prd.log file and restart opal-prd daemon.

rm /var/log/opal-prd.log

systemctl restart opal-prd

head /var/log/opal-prd.log

So looks like its user error.

Looks like logrorate stuff is creating new file with root user. Below change should fix this.

Fred,

Can you look into the proposed change?

Hi all,
thanks Vasant for the investigation. The fix looks good,
I'm just going to check that on Debian as well.
I'll let you know asap,
