I must apologize. After digging through the logs I realized something was wrong with drbd. Presumably, this is why san2 could not be promoted to master/primary. Oddly enough, despite the underlying drbd not functioning, crm_mon was still reporting san1 as being the master.
Regardless, I have been staring at this for 20 hours over the last two days. My mind is mush. I am going to take a healthy weekend off. I hope everyone else gets a chance to enjoy theirs as well.

I see what you are saying. I followed along with the manual and added a file system, set up the co-location, and the ordering. However, I still have the same problem: when san1 is taken off-line san2 simply remains a slave and, now, the file system is removed from the list of resources. When I bring san1 back online it becomes the master and the filesystem reappears in the list of resources. Here is my updated configuration: node san1 \ attributes standby="off" node san2 primitive drbd ocf:linbit:drbd \ params drbd_resource="r0" \ op monitor interval="60s" primitive fs ocf:heartbeat:Filesystem \ params device="/dev/drbd0" directory="/mnt" fstype="ext3" ms msdrbd drbd \ meta master-max="1" master-node-max="1" clone-max="2" clone-node-max="1" notify="true" colocation fs-on-drbd inf: fs msdrbd:Master order drbd-then-fs inf: msdrbd:promote fs:start property $id="cib-bootstrap-options" \ dc-version="1.1.5-01e86afaaa6d4a8c4836f68df80ababd6ca3902f" \ cluster-infrastructure="openais" \ expected-quorum-votes="2" \ no-quorum-policy="ignore" \ stonith-enabled="false" rsc_defaults $id="rsc-options" \ resource-stickiness="100" These are the only two computers in this network and nothing is appearing in the logs.

You need a promote constraint and a resource depending on Master, IMHO. Cheers, Vadym
