From d89e666e0666a0023e4aa6b6b4c4d25d049c5215 Mon Sep 17 00:00:00 2001 From: zhanghailiang Date: Thu, 27 Oct 2016 14:43:03 +0800 Subject: COLO: Add 'x-colo-lost-heartbeat' command to trigger failover We leave users to choose whatever heartbeat solution they want, if the heartbeat is lost, or other errors they detect, they can use experimental command 'x_colo_lost_heartbeat' to tell COLO to do failover, COLO will do operations accordingly. For example, if the command is sent to the Primary side, the Primary side will exit COLO mode, does cleanup work, and then, PVM will take over the service work. If sent to the Secondary side, the Secondary side will run failover work, then takes over PVM's service work.
