[linux-lvm] vgreduce --removemissing does not remove missing



We have had a disk failure and are trying to recover
what we can.  Having seen that there were major disk
problems we were running pvmove but, alas, it never
finished.  I don't care that much about the data on
the disk but I am puzzled as to why 'vgreduce
--removemissing' reports that it is removing logical
volumes but does not actually seem to do anything. 
When I run vgscan this is what I get:

Reading all physical volumes.  This may take a
while...
/dev/cdrom: open failed: No medium found
Couldn't find device with uuid
'Ay85t2-628y-fE0f-js0t-8RO4-WAy4-9qbaZy'.
Couldn't find all physical volumes for volume group
VolGroup00.
Volume group "VolGroup00" not found
Found volume group "VolGroup01" using metadata type
lvm2

Then I run:
vgreduce --verbose --removemissing VolGroup00
Finding volume group "VolGroup00"
Couldn't find device with uuid
'Ay85t2-628y-fE0f-js0t-8RO4-WAy4-9qbaZy'.

It looks to me that it is removing the pvmove0 LV but
when I run vgscan again it says the same thing about
not finding device with uuid ...  Am I not
understanding what vgreduce is trying to do or should
that pv have been removed?
