No, you cannot have a VG used by more than one package. A VG can be used by one and ONLY one package.

Well, at one time only one node can access a volume group. If two will access them at the same time then the data in the volume group will be corrupted. So, one node at a time. To give acces to one node u should use
vgchange -a y vgname on that particular node.
Or vgchange -a n vgname on the node u want to stop the access on, and then use the -a y option on the one u want to work on.
