pvmove: Physical Volume "/dev/sdc1" not found in Volume Group + minor bug

sudo pvmove -n Win /dev/sda1 /dev/sdc1

lvs #(From volume in HnS)

pvs #(from VG HnS on PV /dev/sda1, destination PV = /dev/sdc1

sudo pvmove -n Win /dev/sda1 /dev/sdc1

sudo modprobe dm-mirror

ls -d /sys/module/dm*

sudo modprobe dm-<COMPLETE>

I'm trying to move an LV from one VG on 1 PV to another VG on another PV, but it doesn't seem to like my syntax. Isn't it: " -n LV FROMPV TOPV"

Quoted 1 line

sudo pvmove -n Win /dev/sda1 /dev/sdc1

Physical Volume "/dev/sdc1" not found in Volume Group "HnS"

Pertinent details:

sudo modprobe dm-<COMPLETE>

I'm assuming I only needed the dm-mirror so it could do the mirroring? What syntax should I be using?

Thanks!

first merg the two vgs using vgmerge command

sudo vgmerge -v Data HnS

lvs|grep HnS

thanks...urk....ok.. long way around...(want to move a house from one city to another,
but first must merge cities, then logical-house-move from one side of the city
to the other; then un-annex the old-part of the city)...;-/

Um... trying the merge, I get:

sudo vgmerge -v Data HnS

Checking for volume group "Data"
Checking for volume group "HnS"
Logical volumes in "HnS" must be inactive

Hmm...

 oHome                    HnS     -wi-a----   1.00t

I guess they are active. But if they aren't open, what are they doing? And how do I make them inactive (I have a feeling this is at the root of why lvremove never works without "-f" as well).
