Anyway, my question is: is this behavior (not using IP aliases) a
feature of heartbeat 3.0.x, or is this an artifact of the CentOS
plumbing the heartbeat invokes? I didn't see anything in the
changelog in a quick perusal.
I think it's a side-effect of RedHat going all entrerprisey with
OpenStack (RDO) and having to bite the pacemaker bullet as a result. I'm
told heartbeat resource scripts have been just wrappers around
pacemaker's resource-agents for some time -- but RedHat's packages
haven't been touched in years. Until now.
It's also a reflection that heartbeat itself hasn't been developed in
years, and there is no plan to restart development either. Linbit still
maintains the existing code and provides support for it, but anyone
starting on new projects should really consider corosync + pacemaker.
Even Red Hat's cman + rgmanager is gone in RHEL 7.
This is a result of a long merger process that started in 2008. The two
independent HA stacks (RHCS and Linux-HA) was dividing the community and
causing a lot of reinvention of the wheel. In the last 5~6 years, both
teams have been working hard to unify under one common open-source HA
stack. Pacemaker + corosync v2+ is the result of all that hard work. :)
