Thanks for your interest and for your help.
Here is the output from command (pcs config show)
[root@lb1 ~]# 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.
Thanks
