can't close logical volume

[Tom Rosenfeld]

Hi Guys,

I am having troupe with an LVM volume. I umounted a disk and moved it to a
new system. There I did pvscan and vgscan --mknodes
However I can do no further operations on the volume since LVM thinks it is
still open. It did not even create the block devise even though lvdisplay
show it exists.

I am looking for a way to force the volume closed, but have not had any
luck.
See the output below.

Thanks,
-tom
