Looks good to me.
But better initially set these up with the default DRBD settings and check if the I/O performance is sufficient. The need to disable Ganeti is really only for I/O latency (etcd is very sensitive to that), but throughput should be fine in practically all cases. Not disabling DRBD will simplify maintenance of the VMs in general (1. they won't go down if a virt node is rebooted and 2. if we upgrade a virt node we'll need to temporarily move them back to DRBD to evict them from the node for the reimage for a bit)
