The whole point of the exercise is to end up with multiple block devices on a single system so that I can combine them into one VG using LVM, and then build a single file system that covers the lot.

Yes, I hear what you are saying. However, I have investigated MooseFS and GlusterFS using the same resources, and my experimental iscsi-based setup gives a file system that is *much* faster than either in practical use, latency notwithstanding.
