Single Point of Failure (SPOF)
A single point of failure (SPOF) is any component of a cluster that, should it fail,
triggers the failure of the entire cluster.
split brain
A scenario in which the cluster nodes are divided into two or more groups that do
not know of each other (either through a software or hardware failure). To prevent
a split brain situation from badly affecting the entire cluster, STONITH must come
to the rescue. Also known as a "partitioned cluster" scenario.
STONITH
The acronym for "Shoot the other node in the head" which is basically bringing
down a misbehaving node to prevent it from causing trouble in the cluster.
transition engine (TE)
The transition engine (TE) takes the policy directives from the PE and carries them
out. The TE always runs on the DC. From there, it instructs the local resource
managers on the others nodes which actions to take.
