lvm question

if one combines a partition from drive 'a' with a partition from drive 'b'
into an lvm partition, what happens if either drive goes bad? is it like
raid 0 where you lose all your data on both?

The entire physical device must be devoted to the VG.
A VG is the uppermost abstraction of LVM.
