I have a VG which had two LVs. I removed the drives for the second LV
from the system without disabling the LV or otherwise letting LVM know.
Now LVM refuses to start the VG back up (which is reasonable behavior).
However, I wish to inform LVM that the two drives I removed are not
going to reappear, and I would like it to start up and just give me the
remaining LV. The --removemissing flag to vgreduce seems like it should
be exactly what I'm looking for, and when run indicates that it is doing
the right thing. But it doesn't seem to actually make any changes.
