To create a clone of a SQL server from scratch (~pseudocode):

* `iptables -A INPUT -p tcp --dport mysql -j REJECT`
* Wait for connections to die down
* `mysql -e "show master status"` and save the output
* `mysqladmin shutdown`
* `umount /path/to/mysqldata`
* `sync`
* `lvcreate -s -L 10G -n snapshot /dev/vg/mysqldata`
* `mount /path/to/mysqldata`
* `/etc/init.d/mysql restart`
* Copy from /dev/vg/mysqldata at your leisure
