libstonithd2 1.1.18-0ubuntu1 (amd64 binary) in ubuntu bionic

 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 STONITH daemon library.
