Hi Ken and Jan,

Thank you for your comment.

I understand that solusion is to set PCMK_logfile in the sysconfig file.

As a permanent fix, if you use the default values inside Pacemaker, how
about setting environment variables using set_daemon_option() there?
For example, as PCMK_logficility does.

BTW, Pacemaker writes to /var/log/pacemaker/pacemaker.log via libqb.
RA writes to this file with echo redirect.
If writing occurs at the same time, is there a risk that the file may be
corrupted or the written log may disappear?
I have never actually had a problem, but I'm interested in how this might
