Not a ha expert, just an opinion.but what i did was to put my drbd and corosync traffic on a private 10g network, i didnt want client/downstream to interfere with cluster communications. Works well for me, but dont know if its applicabe to you. There are utilization rules you can use to prevent the log jam, but i have no experience using them other than knowing they exist.
