I just looked at GlusterFS and VastSky - these seems to be aimed at aggregating storage located across different servers. Correct me if I'm wrong, but this seems to me the opposite of what you are looking for: you want HA, so data needs to be replicated to be available via different servers, right?

I'm running IET. Next project I would try AoE though.

Running anything on top of that in the way of a cluster file system?

IET is running on DRBD - no cluster file system necessary. Pacemaker sees to it that only one node is using the iSCSI connection actively for a particular DomU. You could think about using a cluster file system to offer the Xen config files to all nodes, but I simply fixed this by syncing these files with csync.
