I'm confused.

First I tried:

# lvremove /dev/Home+Space/Home-2011.08.31-02.23.11
Do you really want to remove active logical volume 
Home-2011.08.31-02.23.11? [y/n]: ^C
  Logical volume Home-2011.08.31-02.23.11 not removed


Then, I tried what you had above:

# lvchange -an /dev/Home+Space/Home-2011.08.31-02.23.11     
# lvremove /dev/Home+Space/Home-2011.08.31-02.23.11    
  Logical volume "Home-2011.08.31-02.23.11" successfully removed

Was it not supposed to work?
