Do all the configuration as though there were two nodes, but set "wfc-timeout 0;" to stop that node waiting for a partner. Once you promote it to primary (probably via a split heartbeat cluster) you should be good to go. (/proc/drbd should show Primary/Unknown) When you bring the second node up (make sure the partition/device size is the same!) and you've done the "drbdadm create-md $resource" you should be able to "drbdadm -- --overwrite-data-of-peer primary $resource" on the primary and watch them sync.
