i haven't had any replies from dm-devel mailing list so I tried pvmove onto my external usb drive - i.e. pvmove /dev/sdb2 /dev/sdc3 It is working so far! So, the device-mapper error must refer to /dev/sda2 rather than the source disc as I'd assumed. I'm not sure where this will leave me. My guess is that trying to pvmove from the usb drive to the new disc will give the same error. I don't really want the usb drive hanging off the front of my server, but it will be nice to get rid of the old disc. Maybe I'll just have to buy a new disc.
