[linux-lvm] Removing a very old physical drive - revisited

Like a moth to a flame, I am having another go at removing a physical
drive (30G) from my one and only volgroup.

I left it last night having recovered my system after pvmove created a
phantom lv that was too big to fit on the pv.

Tonight, I tried plugging a usb external 80G drive and doing a pvcreate
on it. This worked fine.

I then vgextended my volgroup to include this new device thinking the
free space would encourage pvmove to work and it would need to be in the
volgroup. This also appears to have worked.

Finally, the dreaded pvmove command that trashed my system last night.
At least it doesn't seem to have harmed anything tonight, but it still
hasn't worked. I've put a line of asterisks where I think the errors
are. Presumably, the second is a consequence of the first. Should I have
executed some dmsetup command before doing the pvmove as some googling
might suggest?

Thank you for any help you can give me.
