Thanks for the reply :-)

If I take the --test, yes the snapshot gets created
But if I try to create a new VG and after a new LV I get the same error. I can 
the work I was supposed to do, but would like to understand what's going 
on......

lvcreate -L 1G -n TEST  vg_mysql_bk
Aborting. Failed to activate new LV to wipe the start of it.

vgdisplay -v vg_mysql_bk
