I found: http://serverfault.com/questions/165883/is-there-a-way-to-add-more-backend-server-to-haproxy-without-restarting-haproxy http://sysbible.org/2008/07/26/haproxy-hot-reconfiguration/ However, these options are last documented in version 1.2: http://haproxy.1wt.eu/download/1.2/doc/haproxy-en.txt A brief search did not uncover any similar documentation in newer versions: http://haproxy.1wt.eu/download/1.3/doc/configuration.txt http://haproxy.1wt.eu/download/1.4/doc/configuration.txt What is the current approved way to do hot reconfiguration?

If one backend was in a down state due to failed health checks, will it be marked up by the new process until it fails the configured number of checks? They're marked UP for one single check (as if they failed all checks but the last one). That way, the first check fixes the status. Regards, Willy
