Markus, I see /etc/lvm/lvm.conf has an option to ignore md members and seems on by default in EL6: md_component_detection = 1 If you run "pvdisplay /dev/sda2" what does it show? Normally you should get a "Failed to read physical volume "/dev/sda2". Do you have such thing in your /etc/lvm/lvm.conf? ADditionally you can force a filter on the drives, smth like: filter = ["r|/dev/sda2"] (make sure you delete /etc/lvm/cache/.cache and regenerate it with vgscan so as not to contain old stuff) -- Sent from the Delta quadrant using Borg technology!
