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. -- john r pierce N 37, W 122 santa cruz ca mid-left coast
