By default, pacemaker will use the same log file as corosync, so this
should be sufficient.

Alternatively, you can explicitly tell Pacemaker what detail log file to
use with the environment variable PCMK_logfile (typically set in a
distro-specific location such as /etc/sysconfig/pacemaker or
/etc/default/pacemaker).
