I'm afraid that since we need the NFS failover between the servers, A + async may not be an option for us :/ Our users would eat us alive. I've tweaked the network settings for DRBD and disabled ACPI on both machines. I'm in the process of testing it. If it helps i'll CC the debriefing here to the list.
