Yea, I had that problem too.  The docs are heavy on basic setup and a
bit sparse on how to actually do anything useful.

This may help.  This is the cluster.conf file from a test cluster I'm
working on.  Note the "resources" section at the bottom.  Based on
your question, I'm not sure if you are doing GFS or not, but maybe
this will point you in the right direction.

Use lvm2 to create the logical volumes on one box and then do a vgscan
on the other box to read the volume group information.
