That's good advice. clvmd will run with 'just' openais, but you need to
configure it yourself and it's not well tested. If you need to adapt
clvmd for other clustering infrastructures then clvmd-openais.c is the
file to adapt as it's by far the simplest. Though it does require that
the cluster software provides messaging as a service.
