LVM Snapshot.

lvm -s -n SnapShotName /dev/VolumeGroup/SourceLogicalVolumeName

you may need to pass -l or -L to give an initial size for the COW.

(as for rebuilding on another machine, that would require shared
storage or additional LVM tricks to export/import - or good old
fashioned dd)

that said, a more appropriate list to question is linux-lvm@redhat.com
