No. But you could modify the resource agent and insert a 2 minute sleep in the start action. If you do that, put the resource agent under your own provider so it doesn't get overwritten on update. > batch-limit will stop multiple resource migration processing in parallel but > can you set the interval between batch-limit? There's also a lrmd parameter called max-children which limits the number of actions run in parallel on one node. The batch-limit limits the number of cluster actions.
