D.2. Sibling Start Ordering and Resource Child Ordering
The Service resource determines the start order and the stop order of a child resource according to whether it designates a child-type attribute for a child resource as follows:
Designates child-type attribute (typed child resource) — If the Service resource designates a child-type attribute for a child resource, the child resource is typed. The child-type attribute explicitly determines the start and the stop order of the child resource.
Does not designate child-type attribute (non-typed child resource) — If the Service resource does not designate a child-type attribute for a child resource, the child resource is non-typed. The Service resource does not explicitly control the starting order and stopping order of a non-typed child resource. However, a non-typed child resource is started and stopped according to its order in /etc/cluster.cluster.conf In addition, non-typed child resources are started after all typed child resources have started and are stopped before any typed child resources have stopped.
The only resource to implement defined child resource type ordering is the Service resource.
For more information about typed child resource start and stop ordering, refer to Section D.2.1, “Typed Child Resource Start and Stop Ordering”. For more information about non-typed child resource start and stop ordering, refer to Section D.2.2, “Non-typed Child Resource Start and Stop Ordering”.
