Hello,
I have a follow up question.
According to the TripleO docs for RHOPS 13/Queens, "you cannot scale
up or scale down a custom role that contains
OS::TripleO::Services::Pacemaker or
OS::TripleO::Services::PacemakerRemote services." Does that only apply
to the role itself or all the pcmk-managed services within the role?
For instance, if I already split out the DB and messaging services
with a custom role, can I later create another custom role just to
scale up the DB service?
Thank you very much.
Regards,
Cody
