New to Haproxy and linux. We have 2 Haproxy VMs load balancing an Exchange 2019 DAG group consisting of 2 Exchange servers.
Recently we tried to put the passive Exchange server into maintenance mode to patch reboot etc. The active Exchange server was able to take email internally as well as send to external clients. The problem is that we were not able to receive from external senders. Both proxy VMs are configured for round robin. Is there a is there a section or a command in the front or back end configuration that is needed when one of the Exchange servers is down for maintenance?
Thanks.
