Bug 2040443

+++ This bug was initially created as a clone of Bug #2039675 +++

Description of problem:
pacemaker-controld repeatedly dumps a core after the ocf:heartbeat:mysql resource is configured in replication mode.


Version-Release number of selected component (if applicable):
pacemaker-2.1.2-2.el8.x86_64
resource-agents-4.9.0-12.el8.x86_64
mysql-server-8.0.26-1.module+el8.4.0+12359+b8928c02.x86_64


How reproducible:
100%

Steps to Reproduce:
1. Set up mysql database for replication
2. Configure ocf:heartbeat:mysql resource for replication


Actual results:
ocf:heartbeat:mysql resource doesnt' work as expected and pacemaker-controld dumps cores

Expected results:
No pacemaker coredumps
