# cibadmin --query --xpath "//nvpair[@name='target-role']"
Remove all 'is-managed' settings:
# cibadmin --delete-all --xpath "//nvpair[@name='is-managed']"
Remove the resource named 'old':
# cibadmin --delete --xml-text '<primitive id="old"/>'
Remove all resources from the configuration:
# cibadmin --replace --scope resources --xml-text '<resources/>'

# cibadmin --replace --xml-file $HOME/pacemaker.xml
Replace the constraints section of the configuration with the contents of $HOME/constraints.xml:
# cibadmin --replace --scope constraints --xml-file $HOME/constraints.xml

# cibadmin --query > $HOME/local.xml
# $EDITOR $HOME/local.xml
