      "...There might be some techniques to make failover faster, but that depends on exactly how you have it set up, what kind of OpenVPN connections you're talking about, etc...." - what methods can automate the switching of openVPN client between master and backup

        I have no idea what you are trying to communicate there. Sorry.

            How to do auto switch?

            Bind the OpenVPN server to the CARP VIP.

              I have configured carp, and everything works fine when switching (master / backup status) between servers, except for one service - "openVPN CLIENT".
              Servise - "openVPN SERVER" - works correctly when rebooting (crashing) servers: "ON status - on master pfsense server and OFF - on backup pfsense server"

                You need to tell the OpenVPN server to listen on a CARP VIP, not the interface address.

                When you do that the server will only run on the node currently holding CARP MASTER.

                Same thing with the client. Set the interface to the CARP VIP.

                  "You need to tell the OpenVPN server to listen on a CARP VIP, not the interface address." - It was done. Сonfigured initially
                  "When you do that the server will only run on the node currently holding CARP MASTER." - Configured initially. The openvpn SERVER is working correctly.
                  "Same thing with the client. Set the interface to the CARP VIP." - Installed .. service does not work correctly

                    When I bind OVPN Client to CARP VIP interface I see two concurent connections on remote OVPN server from real IPs of my master and backup PFSense

                        Did you properly set the CARP VIPs on that gateway group?

                          The problem has been resolved.
                          First, in the settings, OpenVPN / clients / interface installed a group of gateways (consisting of 3 WANs).
                          When I replaced the WAN gateway group with one of the VIP WANs - carp.failover - service-VPNclient switched correctly ...
                          thank

                            You can use a gateway group but you have to set up the gateway group using CARP VIPs.
