After creating , mounting and reading, umount, a lvm can not be lvremoved without several attemps to get some arbartary code path to work.
lvm lvremove /dev/mappe/vg-lvsnap
can't be removed
logout of root
log back in
same thing - it used to work at this point.
exit the terminal altogether.
open terminal
same thing - had to do this as of a 2 week ago.
in rrot term add extra parms to command
lvm lvremove /dev/mapper/vg_host-lv_snaproot lvroot
Gets message to delete y,n
deleted snaproot
lv lvroot not found - #it is an lv and is the lv the snapshot refers to.
lvroot volgroup ignored - it is not a VG?

Update LVM2 to a newer version in F14 to see if anything changed.
Works the same and I noticed specifying a VG it will attempt tp remove all LV on the VG. Not so good.
# rpm -Uvh *.rpm
