Description

The Booth cluster ticket manager is a component to bridge high availability clusters spanning multiple sites, in particular, to provide decision inputs to local Pacemaker cluster resource managers. It operates as a distributed consensus-based service, presumably on a separate physical network. Tickets facilitated by a Booth formation are the units of authorization that can be bound to certain resources. This will ensure that the resources are run at only one (granted) site at a time.

Security Fix(es):
