frankly, I'd temporarily hang a 1TB drive on that thing, format it as a
simple volume, and backup your file systems to it, that raid is a
*MESS*. It would make much more sense to have 1 partition on each
physical disk be a member of the MD raid5, then put that md in the
volgroup, rather than having 9 sets of raids, I can only imagine they
did it the way they did due to limitations of that ancient linux kernel
in RH Linux 7.x (early Kernel 2.4, I believe).
but, a newer linux kernel should see those md volumes, and should be
able to import the LVM VG on them, if you really want to keep it intact.
