I didn't say "self-hacked", this could be a wrapper officially included.
It just seems that pacemaker+corosync+... is overkill for watching the
health of a single service on one node.

(And no, I think I wouldn't want to run pacemaker on my OSD cluster,
because that doesn't scale.)

And, anyway, at this point in time, I'd tell my customers to skip
ceph/RADOS for the next 6-12 months still, but to contact us off-list if
they're interested in PoCs ;-)
