I have a several concerns with that change, 1) Is it possible to recover or cause a fail-over correctly when any of the Pacemaker/Heartbeat process was failed? (In particular, for the failure of the new mcp process of pacemaker and for the current heartbeat's MCP process failure) 2) Would the daemons used with respawn directive such as hbagent(SNMP daemon) or pingd work as compatible? 3) After all, what would be the benefit for end users with the change? I feel like it's only adding some complexity to the operations and the diagnostics by the end users. I guess that I would only use "legacy on" on the heartbeat stack... -- Keisuke MORI _______________________________________________________ Linux-HA-Dev: Linux-HA-Dev@lists.linux-ha.org http://lists.linux-ha.org/mailman/listinfo/linux-ha-dev Home Page: http://linux-ha.org/
