Here it is.  Bit long, because of all the partitions involved.
Apologies for that, but I didn't want to edit it for posting any more
than was absolutely necessary.

It's probably relevant to mention that the failover domains are tagged
as restricted even though they all contain all the current nodes because
at some point I wish to add further nodes that will have access to the
GFS filesystems but won't provide NFS services.
