Comment 1 for bug 1890185

This feature is in 2.0.x releases, so SRU for bionic would be out of question:

 pacemaker | 1.1.18-0ubuntu1 | bionic | source
 pacemaker | 1.1.18-0ubuntu1.1 | bionic-security | source
 pacemaker | 1.1.18-0ubuntu1.2 | bionic-updates | source
 pacemaker | 2.0.1-4ubuntu2 | eoan | source
 pacemaker | 2.0.3-3ubuntu3 | focal | source
 pacemaker | 2.0.4-2ubuntu1 | groovy | source

and Eoan is not LTS so the effort is not worth.

That would make the need for:

To backport

(1)

874f75e0f - Feature: scheduler: new on-fail="demote" recovery policy for promoted resources
2f1e2df1f - Feature: xml: add on-fail="demote" option to resources schema

and all related patches to Focal.

(2)

To make sure Groovy catches up with the feature or to backport similar patches to Groovy.
