[DRBD-user] OL8.5 Pacemaker Fencing

we currently try version DRBD 9.19.1 with Oracle Linux 8.5 and pacemaker. It looks like the latest pacemaker updates did break the fencing script "/usr/lib/drbd/crm-fence-peer.9.sh". After update from OL8.3, we face an issue where DRBD needs a lot of time to become primary when the secondary node is not available. I guess its not an issue of DRBD 9.19.1, cause the issue is also present when we use older versions of DRBD which did work perfectly with OL8.3.

Before the update a failover took around 30 seconds. Now we need more than 30 minutes. From logs and "ps aux" I see, that crm-fence-peer.9.sh is running for each resource and take around 5-10 minutes to complete. Unfortunately there is no error nor any indication what exactly needs that much time now.

Is this a known issue or do you have any ideas how to debug that issue?
