[Pacemaker] Atomic update via crm_resource command

[Jean-Francois Le Breton]

Hello,

   We are wondering if setting a value to a named parameter of a resource
through the crm_resource command is an atomic operation accross the cluster.  

   In other words, is there any underlying consensus protocol (such as Paxos),
or are the CIB modifications "lazy replicated" on all the nodes ( e.g. rcp) ? 


Kindest Regards,

Jean-Francois
