6.2.2. Advisory Ordering
When the
kind=Optional option is specified for an order constraint, the constraint is considered optional and only has an effect when both resources are stopping and/or starting. Any change in state of the first resource you specified has no effect on the second resource you specified.
The following command configures an advisory ordering constraint for the resources named
VirtualIP and dummy_resource,
pcs constraint order VirtualIP then dummy_resource kind=Optional
# pcs constraint order VirtualIP then dummy_resource kind=Optional
