[linux-lvm] Cannot deactivet LV - why?

["Dan Bar Dov" <danb voltaire com>]

I'm trying to do something thst seems very normal to me

bash-2.05a# lvchange -a n /dev/0/idolv1
lvchange -- operation not permitted for (open) logical volume
"/dev/0/idolv1"


Why is the operation not permitted? The LV is not in use, its not
mounted, there's no process using it.

Any ideas?

Thanks,
Dan
