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.

Anyone know what's going on?

--partial doesn't seem to be a valid option for vgreduce.
Or did you mean something like 'lvchange -ay --partial /dev/typhoon/backup'
or 'vgchange -ay --partial typhoon'?
[root@typhoon ~]# lvchange -ay --partial /dev/typhoon/backup

The end result is roughly what the messages indicate, the remaining good
LV is made available read-only. However, lvdisplay and vgdisplay both
still fail and I'm no closer to dumping the unwanted LV and establishing
a clean configuration.
As for versions, I'm running FC3 patched up to the latest and greatest:
[root@typhoon ~]# rpm -q lvm2
lvm2-2.00.25-1.01
[root@typhoon ~]# uname -a
Linux typhoon.aput.net 2.6.11-1.27_FC3 #1 Tue May 17 20:27:37 EDT 2005 i686 athlon i386 GNU/Linux
