pacemaker - 2.0.1-5+deb10u1 main

At its core, Pacemaker is a distributed finite state
machine capable of co-ordinating the startup and recovery of inter-related
services across a set of machines.
.
Pacemaker understands many different resource types (OCF, SYSV, systemd) and
can accurately model the relationships between them (colocation, ordering).
.
It can even use technology such as Docker to automatically isolate the
resources managed by the cluster.
.
This package contains the Pacemaker daemons directly interacting with
the cluster stack.
