<br><br>Thank you for your detailed answer!<br>Corosync.conf is part of the ansible scripts, but corosync and pacemaker are updated with the yum source. So it has caused the current gap. I will carefully compare the gap between the new and old versions<br><br>

<br><br>I did run ocf-tester and the result was passed. Here I carefully read the log. When this error was printed in the log, the latest operation that pacemaker made to the inetmanager's RA was start instead of stop. Why did pacemaker think that the RA should return 7 at this time?<br>I may know the reason for this problem. Because of the implementation of the start and monitor methods in my RA. Because pacemaker recovers one resource at a time, it must wait for other resources that are starting. In order to eliminate this dependency, my RA's start method is just a startup instance and does not wait for business to work. The monitor method will loop to wait for business to be normal. And this can also filter out some occasional monitor failures. However, I tested and found that from the start of the start until the first monitor is successful, it will also block the scheduling of other resources. Inetmanager is the cause of the problem. Is my analysis correct? If so, how should I solve it?<br><br>
