This is more of a exercise than a real world use example. I have used something similar in a disater recovery situation so it does have some merit ..but good planning can prevent needing hacks like this.

DD IS DESTRUCTIVE USE IT WITH CAUTION AND UNDERSTANDING OF WHAT YOU ARE RUNNING!…ok now that is out of the way…

for i in $(pvdisplay | awk '/PV Name/ {print $3}'); do
dd if=$i of=/tmp/lvm_config_for_$(echo $i |sed 's/\//_/g') bs=$(stat -f -c %s $i) count=10;
done
