Thanks for your interest and for your help. Here is the output from command (pcs config show)

When I start cluster after reboot of both nodes, everythings looks fine. But when shoot command "pcs resource delete OPENVPN" from node lb1 in the log starts to popup these lines: Jan 15 13:56:37 corosync [TOTEM ] Retransmit List: 202 Jan 15 13:57:08 corosync [TOTEM ] Retransmit List: 202 203 Jan 15 13:57:38 corosync [TOTEM ] Retransmit List: 202 203 204 Jan 15 13:58:08 corosync [TOTEM ] Retransmit List: 202 203 204 206 Jan 15 13:58:38 corosync [TOTEM ] Retransmit List: 202 203 204 206 208 Jan 15 13:59:08 corosync [TOTEM ] Retransmit List: 202 203 204 206 208 209
I also noticed, that these retransmit entries starts to appear even after some time (7 minutes) from fresh cluster start without doing any change or manipulation with cluster.
there exists multicast issues on virtual nodes - therefore your bridged network will for sure not operate reliable out of the box for HA setups.
