Good morning gentlemen! Alex raised very good question. Thank you very much! We have 3 init systems right now. Some services use SystemV, some services use upstart, some services are under pacemaker. Personally, I would like to have pacemaker as pid 1 to replace init [1]. However, I would like to remove custom scripts as much as possible to leave only upstart/systemd classes [2] only. That move will give fantastic flexibility to operators to control their services.
Concerning Haproxy checker, I think it should be done in different way. If pacemaker/corosyunc has an issue the node should be fenced. Also, I would like to have pacemaker remote to control services on compute nodes. It's very good replacement for monit.
