[Bogdan Dobrelya (bogdando)]

Issue should be addressed by updating the Pacemaker and Corosync stack

[Sergii Golovatiuk (sgolovatiuk)]

This issue should go away after upgrading Corosync to 2.X. Since we are in feature freeze, corosync 2.x packages will be added to 6.1

[Sergii Golovatiuk (sgolovatiuk)]

This bug is invalid as we switched to corosync 2.0. I cannot see such warnings anymore.
