Pacemaker ships with a logrotate snippet. If you installed a stock
package, your distribution should have installed that automatically.

If you're building yourself, just install extra/logrotate/pacemaker
from the pacemaker source to /etc/logrotate.d (assuming you're using
logrotate).

If you've changed the log file location, just edit the logrotate.d file
appropriately.

Pacemaker uses the "copytruncate" method of log rotation, so there's no
need for pacemaker to reopen the log after rotation.
