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?

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.
