The reason the results are likely so sparse is because the two modes  
of operation (single machine and cluster) are so similar.

Once you've setup a cluster and installed the lvm2-cluster rpm*, new  
volume groups that are created automatically receive the "clustered"  
attribute.  [Toggle the cluster attribute by doing vgchange -c[ny]  
<vg>]  The lvm commands stay the same as if you were running them on a  
single machine.**

* Of course you could compile the sources or use another install method.
** Some targets (like snapshots) are not available when using LVM in a  
clustered mode.
