This is a wrapper for the LVM2 administration utility, lvm. Its primary function it to convert physical volumes, logical volumes and volume groups into easy to use ruby objects. It also provides a simple wrapper for typical create/delete/etc operations. Unfortunately due to it's lack of a proper api this is as good as it gets for ruby integration for the forseeable future. See this thread http://www.redhat.com/archives/libvir-list/2007-March/msg00192.html for a similar discussion.
