This is a terrible idea. Note that if you have say 40mb/sec on regular
lvm partition, you will be reduced to about 10mb/sec on the cow. also,
major fs intensive things are likely to kill your cow. (i have noticed
nessus completely ruining a lvm snapshot). because of this, there is
work being done to create a real cow fs in replacement of lvm snapshots.
