You can have nodes mounting volumes exported by different iscsi hosts,
as long as the volumes exported are different. As in, if two exported 
volumes
are the same, then that won't work.

OCFS2 is a shared disk clustered file system. It allows multiple nodes
to concurrently access the file system on a shared device.
