Thanks, I was a bit worried as one time I reassembled a machine with two drives swapped around accidentally; hdc and hde were swapped and had PV's in the same VG. LVM got terribly confused even though vgscan is run at boot time. Fortunately I had just taken a backup before starting otherwise I'd have lost lots of data!
