LVM not, the MD-Layer does if you patch it.  Such a patch has been in
development by and been finished by ca 70% when I notices that Ingo Molnar,
the maintainer of the MD-Layer had already written such a patch which
RedHat hides in it's kernel RPM.  Download their kernel SRPM and look for
two of the thousands of patches that contain 'multipath' in their name.
